docs: add CHANGELOG entry for version 1.3.0

Enable non-localhost connections by specifying allowed IPs/CIDRs in
settings (e.g., 100.64.0.0/10 for Tailscale). Server auto-binds to
0.0.0.0 when remote IPs are configured, with three-layer validation
(source IP, CORS, host header) plus mandatory Bearer token auth.

 ---
 
+## [1.3.0] - 2026-02-06
+
+### Added
+- **Remote IP access**: New `allowedIPs` setting accepts comma-separated IPs and CIDR ranges (e.g., `100.64.0.0/10` for Tailscale) to allow non-localhost connections
+  - Server automatically binds to `0.0.0.0` when remote IPs are configured, otherwise stays on `127.0.0.1`
+  - Three-layer network validation: source IP check, CORS origin check, and host header validation
+  - Bearer token authentication remains mandatory for all connections
+  - Localhost is always implicitly allowed — cannot lock out local access
+  - IPv4-mapped IPv6 addresses (`::ffff:x.x.x.x`) handled transparently
+  - New `network-utils` module with CIDR parsing and IP matching (no external dependencies)
+  - Security warning displayed in settings when remote access is enabled
+
+---
+
+## [1.2.0] - 2026-01-31
+
+### Added
+- **Line Numbers for `read_note`**: New `withLineNumbers` option prefixes each line with its 1-indexed line number (e.g., `1→# Title`, `2→Content`)
+  - Returns `totalLines` count for easy reference
+  - Designed for use with `update_sections` to ensure accurate line-based edits
+  - Example: `read_note("note.md", { withLineNumbers: true })` returns numbered content
+
+- **Force Parameter for `update_sections`**: New `force` parameter allows bypassing the version check
+  - Use `force: true` to skip the `ifMatch` requirement (not recommended for normal use)
+  - Intended for scenarios where you intentionally want to overwrite without checking
+
+### Changed
+- **`read_note` Always Returns `versionId`**: The response now always includes `versionId` for concurrency control
+  - Previously only returned when `parseFrontmatter: true`
+  - Enables safe `update_sections` workflows by providing the ETag upfront
+
+### Breaking Changes
+- **`update_sections` Now Requires `ifMatch`**: The `ifMatch` parameter is now required by default
+  - Prevents accidental overwrites when file content has changed since reading
+  - Get `versionId` from `read_note` response and pass it as `ifMatch`
+  - To opt-out, pass `force: true` (not recommended)
+  - Error message guides users on proper usage workflow
+
+---
+
+## [1.1.4] - 2025-12-20
+
+### Fixed
+- **Template Literal Type Safety**: Fixed type error in `notifications.ts` where `args.recursive` could produce `[object Object]` when stringified
+  - Added explicit `String()` coercion for unknown types in template literals
+
+- **File Deletion API**: Replaced `Vault.trash()` with `FileManager.trashFile()` per Obsidian guidelines
+  - All file deletions now respect user's configured deletion preference (system trash or `.trash/` folder)
+  - Removed unused `trash()` method from `IVaultAdapter` interface and `VaultAdapter` class
+  - Both soft and regular delete operations now use the same user-preferred deletion method
+
+### Changed
+- `delete_note` destination field now returns `'trash'` instead of `.trash/{filename}` since actual location depends on user settings
+
+---
+
+## [1.1.3] - 2025-12-16
+
+### Fixed
+- **Sentence Case**: Fixed remaining UI text violations
+  - `main.ts`: "Toggle MCP Server" → "Toggle MCP server"
+  - `settings.ts`: "Authentication & Configuration" → "Authentication & configuration"
+  - `settings.ts`: "UI Notifications" → "UI notifications"
+
+- **Promise Handling**: Improved async/promise patterns per Obsidian guidelines
+  - `main.ts`: Changed `async onunload()` to synchronous with `void this.stopServer()`
+  - `routes.ts`: Wrapped async Express handler with void IIFE pattern
+  - `mcp-server.ts`: Promise rejection now always uses Error instance
+
+- **Async/Await Cleanup**: Removed `async` from 7 methods that contained no `await`:
+  - `mcp-server.ts`: `handleInitialize`, `handleListTools`
+  - `vault-tools.ts`: `getVaultInfo`, `listNotes`, `createFileMetadataWithFrontmatter`, `exists`, `resolveWikilink`
+  - `link-utils.ts`: `validateLinks`
+
+- **Type Safety**: Replaced `any` types with `Record<string, unknown>` and removed eslint-disable directives
+  - `mcp-server.ts`: Tool arguments type
+  - `tools/index.ts`: `callTool` args parameter
+  - `notifications.ts`: `args` interface field, `showToolCall` parameter, `formatArgs` parameter
+
+- **Import Statements**: Eliminated forbidden `require()` imports
+  - `crypto-adapter.ts`: Replaced `require('crypto')` with `globalThis.crypto`
+  - `encryption-utils.ts`: Replaced bare `require('electron')` with `window.require` pattern
+
+### Changed
+- Updated test mocks to match new synchronous method signatures and import patterns
+
+---
+
+## [1.1.2] - 2025-11-15
+
+### Fixed
+- **Code Review Issues**: Addressed all issues from Obsidian plugin submission review
+  - **Type Safety**: Added eslint-disable comments with justifications for all necessary `any` types in JSON-RPC tool argument handling
+  - **Command IDs**: Removed redundant plugin name prefix from command identifiers (BREAKING CHANGE):
+    - `start-mcp-server` → `start-server`
+    - `stop-mcp-server` → `stop-server`
+    - `restart-mcp-server` → `restart-server`
+  - **Promise Handling**: Added `void` operator for intentional fire-and-forget promise in notification queue processing
+  - **ESLint Directives**: Added descriptive explanations to all eslint-disable comments
+  - **Switch Statement Scope**: Wrapped case blocks in braces to fix lexical declaration warnings in glob pattern matcher
+  - **Regular Expression**: Added eslint-disable comment for control character validation in Windows path checking
+  - **Type Definitions**: Changed empty object type `{}` to `object` in MCP capabilities interface
+  - **Import Statements**: Added comprehensive justifications for `require()` usage in Electron/Node.js modules (synchronous access required)
+  - **Code Cleanup**: Removed unused imports (`MCPPluginSettings`, `TFile`, `VaultInfo`)
+
+### Changed
+- Command IDs simplified to remove redundant plugin identifier (may affect users with custom hotkeys)
+
+### Documentation
+- Enhanced inline code documentation for ESLint suppressions and require() statements
+- Added detailed rationale for synchronous module loading requirements in Obsidian plugin context
+
+---
+
+## [1.1.1] - 2025-11-07
+
+### Fixed
+- **Type Safety**: Replaced all `any` types with properly defined TypeScript interfaces and types throughout the codebase
+  - Defined `ElectronSafeStorage` interface for Electron's safeStorage API
+  - Created `LegacySettings` interface for settings migration
+  - Defined `JSONValue`, `JSONRPCParams`, and `JSONSchemaProperty` types for JSON-RPC and MCP protocol
+  - Created `YAMLValue` and `FrontmatterValue` types for frontmatter handling
+  - Updated middleware to use proper Express types (`NextFunction`, `JSONRPCResponse`)
+- **Console Logging**: Removed all `console.log` statements to comply with Obsidian plugin submission requirements
+  - Replaced user-controlled logging with `console.debug` for optional tool call logging
+  - Only `console.warn`, `console.error`, and `console.debug` methods remain
+- **Promise Handling**: Fixed async callback handling in DOM event listeners
+  - Wrapped async event handlers with void IIFE pattern to properly handle promises in void contexts
+  - Fixed 7 event listeners in settings UI and notification history
+- **Import Statements**: Improved `require()` usage with proper TypeScript typing and ESLint directives
+  - Added type assertions for Electron and Node.js crypto modules
+  - Included justification comments for necessary `require()` usage
+- **Settings UI**: Replaced direct DOM `createElement()` calls with Obsidian's `Setting.setHeading()` API
+  - Updated all heading elements in settings tab to use official API
+- **Text Formatting**: Applied sentence case to all user-facing text per Obsidian UI guidelines
+  - Updated command names, setting labels, button text, and notice messages
+- **Code Quality**: Various cleanup improvements
+  - Removed unused `vault.delete()` method in favor of `trashFile()`
+  - Fixed regex character class format from `\x00-\x1F` to `\u0000-\u001F` for clarity
+  - Verified no unused imports, variables, or switch case scoping issues
+
+### Documentation
+- Added comprehensive verification report documenting all fixes for plugin submission review
+
+---
+
+## [1.1.0] - 2025-10-30
+
+### Added
+- **Word Count**: `create_note`, `update_note`, and `update_sections` now automatically return word count for the note content
+  - Excludes YAML frontmatter and Obsidian comments (`%% ... %%`) from word count
+  - Includes all other content (code blocks, inline code, headings, lists, etc.)
+- **Link Validation**: `create_note`, `update_note`, and `update_sections` now automatically validate all wikilinks and embeds
+  - Validates basic wikilinks (`[[Note]]`), heading links (`[[Note#Heading]]`), and embeds (`![[file.ext]]`)
+  - Categorizes links as: valid, broken notes (note doesn't exist), or broken headings (note exists but heading missing)
+  - Returns detailed broken link information including line number and context snippet
+  - Provides human-readable summary (e.g., "15 links: 12 valid, 2 broken notes, 1 broken heading")
+  - Can be disabled via `validateLinks: false` parameter for performance-critical operations
+- **Word Count for Read Operations**: Extended word count support to read operations
+  - `read_note` now automatically includes `wordCount` when returning content (with `withContent` or `parseFrontmatter` options)
+  - `stat` supports optional `includeWordCount` parameter to compute word count (with performance warning)
+  - `list` supports optional `includeWordCount` parameter to compute word count for all files (with performance warning)
+  - All read operations use the same word counting rules as write operations (excludes frontmatter and Obsidian comments)
+  - Best-effort error handling: unreadable files are skipped in batch operations without failing the entire request
+
+### Changed
+- `create_note`, `update_note`, and `update_sections` response format now includes `wordCount` and optional `linkValidation` fields
+- `updateNote` now returns structured JSON response instead of simple success message (includes success, path, versionId, modified, wordCount, linkValidation)
+- `read_note` response now includes `wordCount` field when returning content
+- `stat` response includes optional `wordCount` field in metadata when `includeWordCount: true`
+- `list` response includes optional `wordCount` field for each file when `includeWordCount: true`
+- Type definitions updated: `ParsedNote` and `FileMetadata` interfaces now include optional `wordCount?: number` field
+
+---
+
+## [1.0.1] - 2025-10-28
+
+### Fixed
+- Updated config path examples from `.obsidian/**` to `templates/**` in tool descriptions to avoid implying hardcoded configuration directory paths
+- Removed "MCP Server" from command display names per Obsidian plugin guidelines (commands now show as "Start server", "Stop server", etc.)
+- Replaced deprecated `vault.delete()` with `app.fileManager.trashFile()` to respect user's trash preferences configured in Obsidian settings
+- Extracted all inline JavaScript styles to semantic CSS classes with `mcp-*` namespace for better maintainability and Obsidian plugin compliance
+- Applied CSS extraction to notification history modal for consistency
+
+### Changed
+- Command palette entries now display shorter names without redundant plugin name prefix
+- File deletion operations now respect user's configured trash location (system trash or `.trash/` folder)
+- Settings panel and notification history UI now use centralized CSS classes instead of inline styles
+
+---

+# ObsidianReviewBot Fixes Design
+
+**Date:** 2025-10-28
+**Status:** Approved
+**PR:** https://github.com/obsidianmd/obsidian-releases/pull/8298
+
+## Overview
+
+This design addresses all required issues identified by ObsidianReviewBot for the MCP Server plugin submission to the Obsidian community plugin repository.
+
+## Required Fixes
+
+1. **Config path documentation** - Update hardcoded `.obsidian` examples to generic alternatives
+2. **Command naming** - Remove "MCP Server" from command display names
+3. **File deletion API** - Replace `vault.delete()` with `app.fileManager.trashFile()`
+4. **Inline styles** - Extract 90+ JavaScript style assignments to CSS with semantic class names
+
+## Implementation Strategy
+
+**Approach:** Fix-by-fix across files - Complete one type of fix across all affected files before moving to the next fix type.
+
+**Benefits:**
+- Groups related changes together for clearer git history
+- Easier to test each fix type independently
+- Simpler code review with focused commits
+
+## Fix Order and Details
+
+### Fix 1: Config Path Documentation
+
+**Files affected:** `src/tools/index.ts`
+
+**Changes:**
+- Line 235: Update exclude pattern example from `['.obsidian/**', '*.tmp']` to `['templates/**', '*.tmp']`
+- Line 300: Same update for consistency
+
+**Rationale:** Obsidian's configuration directory isn't necessarily `.obsidian` - users can configure this. Examples should use generic folders rather than system directories.
+
+**Risk:** None - documentation only, no functional changes
+
+### Fix 2: Command Naming
+
+**Files affected:** `src/main.ts`
+
+**Changes:**
+- Line 54: "Start MCP Server" → "Start server"
+- Line 62: "Stop MCP Server" → "Stop server"
+- Line 70: "Restart MCP Server" → "Restart server"
+
+**Note:** Command IDs remain unchanged (stable API requirement)
+
+**Rationale:** Obsidian plugin guidelines state command names should not include the plugin name itself.
+
+**Risk:** Low - purely cosmetic change to command palette display
+
+### Fix 3: File Deletion API
+
+**Files affected:** `src/tools/note-tools.ts`
+
+**Changes:**
+- Line 162: `await this.vault.delete(existingFile)` → `await this.fileManager.trashFile(existingFile)`
+- Line 546: `await this.vault.delete(file)` → `await this.fileManager.trashFile(file)`
+
+**Context:**
+- Line 162: Overwrite conflict resolution when creating files
+- Line 546: Permanent delete operation (when soft=false)
+
+**Rationale:** Use `app.fileManager.trashFile()` instead of direct deletion to respect user's trash preferences configured in Obsidian settings.
+
+**Risk:** Medium - changes deletion behavior, requires testing both scenarios
+
+**Testing:**
+- Verify overwrite conflict resolution still works
+- Verify permanent delete operation respects user preferences
+- Confirm files go to user's configured trash location
+
+### Fix 4: Inline Styles to CSS
+
+**Files affected:**
+- `styles.css` (add new classes)
+- `src/settings.ts` (remove inline styles, add CSS classes)
+
+**New CSS Classes:**
+
+```css
+/* Authentication section */
+.mcp-auth-section { margin-bottom: 20px; }
+.mcp-auth-summary {
+  font-size: 1.17em;
+  font-weight: bold;
+  margin-bottom: 12px;
+  cursor: pointer;
+}
+
+/* API key display */
+.mcp-key-display {
+  padding: 12px;
+  background-color: var(--background-secondary);
+  border-radius: 4px;
+  font-family: monospace;
+  font-size: 0.9em;
+  word-break: break-all;
+  user-select: all;
+  cursor: text;
+  margin-bottom: 16px;
+}
+
+/* Tab navigation */
+.mcp-config-tabs {
+  display: flex;
+  gap: 8px;
+  margin-bottom: 16px;
+  border-bottom: 1px solid var(--background-modifier-border);
+}
+
+.mcp-tab {
+  padding: 8px 16px;
+  border: none;
+  background: none;
+  cursor: pointer;
+  border-bottom: 2px solid transparent;
+}
+
+.mcp-tab-active {
+  border-bottom-color: var(--interactive-accent);
+  font-weight: bold;
+}
+
+/* Config display */
+.mcp-config-display {
+  padding: 12px;
+  background-color: var(--background-secondary);
+  border-radius: 4px;
+  font-size: 0.85em;
+  overflow-x: auto;
+  user-select: text;
+  cursor: text;
+  margin-bottom: 12px;
+}
+
+/* Helper text */
+.mcp-file-path {
+  padding: 8px;
+  background-color: var(--background-secondary);
+  border-radius: 4px;
+  font-family: monospace;
+  font-size: 0.9em;
+  margin-bottom: 12px;
+  color: var(--text-muted);
+}
+
+.mcp-usage-note {
+  font-size: 0.9em;
+  color: var(--text-muted);
+  font-style: italic;
+}
+
+/* Additional utility classes */
+.mcp-heading {
+  margin-top: 24px;
+  margin-bottom: 12px;
+}
+
+.mcp-container { margin-bottom: 20px; }
+
+.mcp-button-group {
+  display: flex;
+  gap: 8px;
+  margin-bottom: 12px;
+}
+
+.mcp-label {
+  margin-bottom: 4px;
+  font-size: 0.9em;
+  color: var(--text-muted);
+}
+```
+
+**Changes to settings.ts:**
+- Remove all `.style.` property assignments (90+ lines)
+- Add corresponding CSS class names using `.addClass()` or `className` property
+- Preserve dynamic styling for tab active state (use conditional class application)
+
+**Rationale:** Obsidian plugin guidelines require styles to be in CSS files rather than applied via JavaScript. This improves maintainability and follows platform conventions.
+
+**Risk:** High - largest refactor, visual regression possible
+
+**Testing:**
+- Build and load in Obsidian
+- Verify settings panel appearance unchanged in both light and dark themes
+- Test all interactive elements: collapsible sections, tabs, buttons
+- Confirm responsive behavior
+
+## Testing Strategy
+
+**After each fix:**
+1. Run `npm test` - ensure no test failures
+2. Run `npm run build` - verify TypeScript compilation
+3. Check for linting issues
+
+**Before final commit:**
+1. Full test suite passes
+2. Clean build with no warnings
+3. Manual smoke test of all settings UI features
+4. Visual verification in both light and dark themes
+
+## Success Criteria
+
+- All 4 ObsidianReviewBot required issues resolved
+- No test regressions
+- No visual regressions in settings panel
+- Clean build with no TypeScript errors
+- Ready for PR re-submission

+
+## Task 3: Fix File Deletion API
+
+**Files:**
+- Modify: `src/tools/note-tools.ts:162`
+- Modify: `src/tools/note-tools.ts:546`
+
+**Step 1: Replace vault.delete() in overwrite scenario (line 162)**
+
+In `src/tools/note-tools.ts`, find the overwrite conflict resolution code around line 157-163:
+
+```typescript
+} else if (onConflict === 'overwrite') {
+	// Delete existing file before creating
+	const existingFile = PathUtils.resolveFile(this.app, normalizedPath);

+
+In `src/tools/note-tools.ts`, find the permanent deletion code around line 544-547:
+
+```typescript
+} else {
+	// Permanent deletion
+	await this.fileManager.trashFile(file);
+}
+```
+
+**Step 3: Verify changes**
+
+Run: `npm run build`
+Expected: Clean build with no TypeScript errors
+
+**Step 4: Run tests**
+
+Run: `npm test`
+Expected: All 716 tests pass (the test mocks should handle both APIs)
+
+**Step 5: Run specific note-tools tests**
+
+Run: `npm test -- tests/note-tools.test.ts`
+Expected: All note-tools tests pass, including:
+- createNote with onConflict='overwrite'
+- deleteNote with soft=false
+
+**Step 6: Commit**
+
+```bash
+git add src/tools/note-tools.ts
+git commit -m "fix: use fileManager.trashFile instead of vault.delete
+
+- Replace vault.delete() with app.fileManager.trashFile()
+- Respects user's trash preferences in Obsidian settings
+- Applies to both overwrite conflicts and permanent deletes
+- Addresses ObsidianReviewBot feedback"
+```
+
+---
+
+## Task 4: Extract Inline Styles to CSS
+
+**Files:**
+- Modify: `styles.css` (add new classes)
+- Modify: `src/settings.ts` (remove inline styles, add CSS classes)
+
+**Step 1: Add CSS classes to styles.css**
+
+Append the following CSS classes to `styles.css`:
+
+```css
+/* MCP Settings Panel Styles */
+
+/* Authentication section */
+.mcp-auth-section {
+	margin-bottom: 20px;
+}
+
+.mcp-auth-summary {
+	font-size: 1.17em;
+	font-weight: bold;
+	margin-bottom: 12px;
+	cursor: pointer;
+}
+
+/* API key display */
+.mcp-api-key-container {
+	margin-bottom: 20px;
+	margin-left: 0;
+}
+
+.mcp-button-group {
+	display: flex;
+	gap: 8px;
+	margin-bottom: 12px;
+}
+
+.mcp-key-display {
+	padding: 12px;
+	background-color: var(--background-secondary);
+	border-radius: 4px;
+	font-family: monospace;
+	font-size: 0.9em;
+	word-break: break-all;
+	user-select: all;
+	cursor: text;
+	margin-bottom: 16px;
+}
+
+/* Headings and containers */
+.mcp-heading {
+	margin-top: 24px;
+	margin-bottom: 12px;
+}
+
+.mcp-container {
+	margin-bottom: 20px;
+}
+
+/* Tab navigation */
+.mcp-tab-container {
+	display: flex;
+	gap: 8px;
+	margin-bottom: 16px;
+	border-bottom: 1px solid var(--background-modifier-border);
+}
+
+.mcp-tab {
+	padding: 8px 16px;
+	border: none;
+	background: none;
+	cursor: pointer;
+	border-bottom: 2px solid transparent;
+	font-weight: normal;
+}
+
+.mcp-tab-active {
+	border-bottom-color: var(--interactive-accent);
+	font-weight: bold;
+}
+
+/* Tab content */
+.mcp-tab-content {
+	margin-top: 16px;
+}
+
+/* Labels and helper text */
+.mcp-label {
+	margin-bottom: 4px;
+	font-size: 0.9em;
+	color: var(--text-muted);
+}
+
+.mcp-file-path {
+	padding: 8px;
+	background-color: var(--background-secondary);
+	border-radius: 4px;
+	font-family: monospace;
+	font-size: 0.9em;
+	margin-bottom: 12px;
+	color: var(--text-muted);
+}
+
+.mcp-usage-note {
+	font-size: 0.9em;
+	color: var(--text-muted);
+	font-style: italic;
+}
+
+/* Config display */
+.mcp-config-display {
+	padding: 12px;
+	background-color: var(--background-secondary);
+	border-radius: 4px;
+	font-size: 0.85em;
+	overflow-x: auto;
+	user-select: text;
+	cursor: text;
+	margin-bottom: 12px;
+}
+
+/* Copy button spacing */
+.mcp-copy-button {
+	margin-bottom: 12px;
+}
+
+/* Notification section */
+.mcp-notif-section {
+	margin-bottom: 20px;
+}
+
+.mcp-notif-summary {
+	font-size: 1.17em;
+	font-weight: bold;
+	margin-bottom: 12px;
+	cursor: pointer;
+}
+```
+
+**Step 2: Update authentication section in settings.ts (lines 199-205)**
+
+In `src/settings.ts`, find the `displayAuthenticationDetails` method around line 199 and replace inline styles:
+
+```typescript
+const authDetails = containerEl.createEl('details', { cls: 'mcp-auth-section' });
+authDetails.open = true;
+const authSummary = authDetails.createEl('summary', {
+	text: 'Authentication',
+	cls: 'mcp-auth-summary'
+});
+```
+
+**Step 3: Update API key container styles (lines 217-224)**
+
+Replace:
+```typescript
+const apiKeyContainer = containerEl.createDiv({ cls: 'mcp-api-key-container' });
+const apiKeyButtonContainer = apiKeyContainer.createDiv({ cls: 'mcp-button-group' });
+```
+
+**Step 4: Update key display container styles (lines 247-255)**
+
+Replace:
+```typescript
+const keyDisplayContainer = apiKeyContainer.createDiv({
+	text: apiKey,
+	cls: 'mcp-key-display'
+});
+```
+
+**Step 5: Update config section headings (lines 260-264)**
+
+Replace:
+```typescript
+const configHeading = containerEl.createEl('h3', {
+	text: 'Connection Configuration',
+	cls: 'mcp-heading'
+});
+const configContainer = containerEl.createDiv({ cls: 'mcp-container' });
+```
+
+**Step 6: Update tab container styles (lines 271-285)**
+
+Replace the tab container creation:
+```typescript
+const tabContainer = configContainer.createDiv({ cls: 'mcp-tab-container' });
+
+const windsurfTab = tabContainer.createEl('button', {
+	text: 'Windsurf',
+	cls: this.activeConfigTab === 'windsurf' ? 'mcp-tab mcp-tab-active' : 'mcp-tab'
+});
+
+const claudeCodeTab = tabContainer.createEl('button', {
+	text: 'Claude Code',
+	cls: this.activeConfigTab === 'claude-code' ? 'mcp-tab mcp-tab-active' : 'mcp-tab'
+});
+```
+
+**Step 7: Update tab content and labels (lines 311-327)**
+
+Replace:
+```typescript
+const tabContent = configContainer.createDiv({ cls: 'mcp-tab-content' });
+
+const fileLocationLabel = tabContent.createDiv({
+	text: 'Configuration file location:',
+	cls: 'mcp-label'
+});
+
+const filePathDisplay = tabContent.createDiv({
+	text: filePath,
+	cls: 'mcp-file-path'
+});
+
+const copyConfigButton = tabContent.createEl('button', {
+	text: 'Copy to Clipboard',
+	cls: 'mcp-copy-button'
+});
+```
+
+**Step 8: Update config display (lines 339-346)**
+
+Replace:
+```typescript
+const configDisplay = tabContent.createEl('pre', { cls: 'mcp-config-display' });
+
+const usageNoteDisplay = tabContent.createDiv({
+	text: usageNote,
+	cls: 'mcp-usage-note'
+});
+```
+
+**Step 9: Update notification section (lines 357-362)**
+
+Replace:
+```typescript
+const notifDetails = containerEl.createEl('details', { cls: 'mcp-notif-section' });
+notifDetails.open = false;
+const notifSummary = notifDetails.createEl('summary', {
+	text: 'Notification Settings',
+	cls: 'mcp-notif-summary'
+});
+```
+
+**Step 10: Update updateConfigTabDisplay method (lines 439-521)**
+
+Find the `updateConfigTabDisplay` method and update the tab button styling to use CSS classes with conditional application:
+
+```typescript
+private updateConfigTabDisplay(containerEl: HTMLElement) {
+	// ... existing code ...
+
+	const tabContainer = containerEl.createDiv({ cls: 'mcp-tab-container' });
+
+	const windsurfTab = tabContainer.createEl('button', {
+		text: 'Windsurf',
+		cls: this.activeConfigTab === 'windsurf' ? 'mcp-tab mcp-tab-active' : 'mcp-tab'
+	});
+
+	const claudeCodeTab = tabContainer.createEl('button', {
+		text: 'Claude Code',
+		cls: this.activeConfigTab === 'claude-code' ? 'mcp-tab mcp-tab-active' : 'mcp-tab'
+	});
+
+	// Update tab content with CSS classes
+	const tabContent = containerEl.createDiv({ cls: 'mcp-tab-content' });
+
+	const fileLocationLabel = tabContent.createDiv({
+		text: 'Configuration file location:',
+		cls: 'mcp-label'
+	});
+
+	const filePathDisplay = tabContent.createDiv({
+		text: filePath,
+		cls: 'mcp-file-path'
+	});
+
+	const copyConfigButton = tabContent.createEl('button', {
+		text: 'Copy to Clipboard',
+		cls: 'mcp-copy-button'
+	});
+
+	const configDisplay = tabContent.createEl('pre', { cls: 'mcp-config-display' });
+
+	const usageNoteDisplay = tabContent.createDiv({
+		text: usageNote,
+		cls: 'mcp-usage-note'
+	});
+}
+```
+
+**Step 11: Verify all inline styles removed**
+
+Run: `grep -n "\.style\." src/settings.ts`
+Expected: No matches (or only legitimate dynamic styling that can't be in CSS)
+
+**Step 12: Build and verify**
+
+Run: `npm run build`
+Expected: Clean build with no TypeScript errors
+
+**Step 13: Run tests**
+
+Run: `npm test`
+Expected: All 716 tests pass
+
+**Step 14: Commit**
+
+```bash
+git add styles.css src/settings.ts
+git commit -m "fix: extract inline styles to CSS with semantic classes
+
+- Add mcp-* prefixed CSS classes for all settings UI elements
+- Remove 90+ inline style assignments from settings.ts

+# Obsidian Plugin Submission Fixes Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Fix all code quality issues identified in the Obsidian plugin submission review to meet community plugin standards.
+
+**Architecture:** Systematic refactoring across the codebase to replace `any` types with proper TypeScript types, remove `console.log` statements, fix command IDs, improve promise handling, use proper UI APIs, convert require() to ES6 imports, and standardize text formatting.
+
+**Tech Stack:** TypeScript, Obsidian API, Express, Node.js
+
+---
+
+## Task 1: Fix Type Safety Issues - Replace `any` Types
+
+**Files:**
+- Modify: `src/main.ts:27`
+- Modify: `src/utils/encryption-utils.ts:2`
+- Modify: `src/types/mcp-types.ts` (multiple locations)
+- Modify: `src/tools/index.ts` (multiple locations)
+- Modify: `src/tools/note-tools.ts` (multiple locations)
+- Modify: `src/tools/vault-tools.ts` (multiple locations)
+- Modify: `src/utils/frontmatter-utils.ts` (multiple locations)
+- Modify: `src/ui/notifications.ts` (multiple locations)
+- Modify: `src/server/middleware.ts` (multiple locations)
+- Modify: `src/adapters/file-manager-adapter.ts` (multiple locations)
+- Modify: `src/adapters/interfaces.ts` (multiple locations)
+- Modify: `src/utils/glob-utils.ts` (multiple locations)
+- Modify: `src/server/mcp-server.ts` (multiple locations)
+- Modify: `src/server/routes.ts` (multiple locations)
+
+**Step 1: Define proper types for Electron safeStorage**
+
+In `src/utils/encryption-utils.ts`, replace the `any` type with a proper interface:
+
+```typescript
+// Define Electron SafeStorage interface
+interface ElectronSafeStorage {
+	isEncryptionAvailable(): boolean;
+	encryptString(plainText: string): Buffer;
+	decryptString(encrypted: Buffer): string;
+}
+
+let safeStorage: ElectronSafeStorage | null = null;
+```
+
+**Step 2: Fix legacy settings migration in main.ts**
+
+In `src/main.ts:27`, replace:
+
+```typescript
+const legacySettings = this.settings as any;
+```
+
+with:
+
+```typescript
+interface LegacySettings extends MCPPluginSettings {
+	enableCORS?: boolean;
+	allowedOrigins?: string[];
+}
+const legacySettings = this.settings as LegacySettings;
+```
+
+**Step 3: Review and fix types in mcp-types.ts**
+
+Read `src/types/mcp-types.ts` and replace all `any` types with proper JSON-RPC and MCP protocol types:
+- Define proper JSONValue type
+- Define proper JSONRPCRequest interface
+- Define proper JSONRPCResponse interface
+- Define proper CallToolResult content types
+
+**Step 4: Fix tool registry types in tools/index.ts**
+
+Replace `any` types with proper tool definition types and CallToolResult types.
+
+**Step 5: Fix note-tools.ts and vault-tools.ts types**
+
+Replace `any` types with proper TFile, TFolder, MetadataCache types from Obsidian API.
+
+**Step 6: Fix frontmatter-utils.ts types**
+
+Replace `any` types with proper YAML value types (string | number | boolean | null | object).
+
+**Step 7: Commit type safety fixes**
+
+```bash
+git add src/
+git commit -m "fix: replace any types with proper TypeScript types"
+```
+
+---
+
+## Task 2: Remove Forbidden console.log Statements
+
+**Files:**
+- Modify: `src/main.ts:21,29`
+- Modify: `src/ui/notifications.ts:94`
+- Modify: `src/server/mcp-server.ts:103,127`
+
+**Step 1: Remove console.log from main.ts**
+
+In `src/main.ts`, remove lines 21 and 29 (API key generation and migration logs). These are informational logs that don't need to be shown to users.
+
+**Step 2: Remove console.log from notifications.ts**
+
+In `src/ui/notifications.ts:94`, the log is controlled by `logToConsole` setting. Keep the functionality but use `console.debug` instead:
+
+```typescript
+if (this.settings.logToConsole) {
+	console.debug(`[MCP] Tool call: ${toolName}`, args);
+}
+```
+
+**Step 3: Remove console.log from mcp-server.ts**
+
+In `src/server/mcp-server.ts:103,127`, remove the server start/stop logs. The UI already shows this status via Notice and status bar.
+
+**Step 4: Verify all console methods are allowed**
+
+Run grep to verify only `warn`, `error`, and `debug` remain:
+
+```bash
+grep -r "console\." src/ | grep -v "console.warn\|console.error\|console.debug" | grep -v "node_modules"
+```
+
+**Step 5: Commit console.log removal**
+
+```bash
+git add src/
+git commit -m "fix: remove console.log statements, use console.debug where needed"
+```
+
+---
+
+## Task 3: Fix Command ID Naming
+
+**Files:**
+- Read: `src/main.ts:52-83` (to identify command IDs)
+- Modify: `manifest.json` (if command IDs are documented there)
+
+**Step 1: Review current command IDs**
+
+Current command IDs in `src/main.ts`:
+- `start-mcp-server` ✓ (correct)
+- `stop-mcp-server` ✓ (correct)
+- `restart-mcp-server` ✓ (correct)
+- `view-notification-history` ✓ (correct)
+
+**Note:** The review mentioned "Three command IDs incorrectly include the plugin name prefix". After reviewing the code, the command IDs do NOT include "mcp-server:" prefix - they use simple kebab-case IDs which is correct. The command NAMES (user-facing text) are also correct and don't include the plugin name.
+
+**Step 2: Verify no issues**
+
+The command IDs are already correct. No changes needed for this task.
+
+**Step 3: Document verification**
+
+```bash
+echo "Command IDs verified - no changes needed" > /tmp/command-id-check.txt
+```
+
+---
+
+## Task 4: Fix Promise Handling Issues
+
+**Files:**
+- Modify: `src/main.ts:16` (onload return type)
+- Modify: `src/tools/note-tools.ts` (async methods without await)
+- Modify: `src/adapters/vault-adapter.ts` (async methods without await)
+- Modify: `src/adapters/file-manager-adapter.ts` (async methods without await)
+- Modify: `src/ui/notifications.ts` (async methods without await)
+- Modify: `src/server/mcp-server.ts` (async methods without await)
+
+**Step 1: Fix onload return type**
+
+In `src/main.ts:16`, the `onload()` method is async but Plugin.onload expects void. This is actually fine - Obsidian's Plugin class allows async onload. Verify this is not a false positive by checking if there are any actual issues.
+
+**Step 2: Review async methods without await**
+
+Search for async methods that don't use await and may not need to be async:
+
+```bash
+grep -A 20 "async " src/**/*.ts | grep -v "await"
+```
+
+**Step 3: Fix methods that return Promise in void context**
+
+Look for callback functions that are async but used where void is expected:
+- Button click handlers
+- Event listeners
+- Command callbacks
+
+Wrap these with void operators or handle promises properly:
+
+```typescript
+// Before:
+.onClick(async () => {
+	await this.doSomething();
+})
+
+// After (if in void context):
+.onClick(() => {
+	void this.doSomething();
+})
+```
+
+**Step 4: Ensure error rejection uses Error objects**
+
+Search for promise rejections that don't use Error objects:
+
+```typescript
+// Before:
+return Promise.reject('message');
+
+// After:
+return Promise.reject(new Error('message'));
+```
+
+**Step 5: Commit promise handling fixes**
+
+```bash
+git add src/
+git commit -m "fix: improve promise handling and async/await usage"
+```
+
+---
+
+## Task 5: Convert require() to ES6 Imports
+
+**Files:**
+- Modify: `src/utils/encryption-utils.ts:4`
+- Modify: `src/utils/crypto-adapter.ts:20`
+
+**Step 1: Convert encryption-utils.ts**
+
+In `src/utils/encryption-utils.ts`, replace:
+
+```typescript
+let safeStorage: ElectronSafeStorage | null = null;
+try {
+	const electron = require('electron');
+	safeStorage = electron.safeStorage || null;
+} catch (error) {
+	console.warn('Electron safeStorage not available, API keys will be stored in plaintext');
+}
+```
+
+with:
+
+```typescript
+import { safeStorage as electronSafeStorage } from 'electron';
+
+let safeStorage: ElectronSafeStorage | null = null;
+try {
+	safeStorage = electronSafeStorage || null;
+} catch (error) {
+	console.warn('Electron safeStorage not available, API keys will be stored in plaintext');
+}
+```
+
+**Step 2: Convert crypto-adapter.ts**
+
+In `src/utils/crypto-adapter.ts:20`, replace:
+
+```typescript
+if (typeof global !== 'undefined') {
+	const nodeCrypto = require('crypto');
+	if (nodeCrypto.webcrypto) {
+		return nodeCrypto.webcrypto;
+	}
+}
+```
+
+with:
+
+```typescript
+if (typeof global !== 'undefined') {
+	try {
+		// Dynamic import for Node.js crypto - bundler will handle this
+		const crypto = await import('crypto');
+		if (crypto.webcrypto) {
+			return crypto.webcrypto;
+		}
+	} catch {
+		// Crypto module not available
+	}
+}
+```
+
+However, since this is in a synchronous function, we need a different approach. Use top-level import with try-catch:
+
+```typescript
+// At top of file
+let nodeCrypto: typeof import('crypto') | null = null;
+try {
+	nodeCrypto = require('crypto'); // This will be transformed by bundler
+} catch {
+	// Not in Node environment
+}
+
+// In getCrypto():
+if (typeof global !== 'undefined' && nodeCrypto?.webcrypto) {
+	return nodeCrypto.webcrypto;
+}
+```
+
+Actually, the best approach for Obsidian plugins is to use conditional imports at the top level:
+
+```typescript
+import type * as CryptoModule from 'crypto';
+
+let nodeCrypto: typeof CryptoModule | null = null;
+if (typeof process !== 'undefined') {
+	// eslint-disable-next-line @typescript-eslint/no-var-requires
+	nodeCrypto = require('crypto');
+}
+```
+
+But this still uses require. For Obsidian plugins, the recommended approach is to mark it as external in the build config and use dynamic import(). However, since this is in a sync function, we need to restructure.
+
+The cleanest solution: Move the require to top-level with proper typing and accept that require() is necessary here for sync crypto access:
+
+```typescript
+// Add at top of file
+import type { webcrypto } from 'crypto';
+
+// Conditionally load Node.js crypto for environments that have it
+let nodeWebCrypto: typeof webcrypto | undefined;
+try {
+	// Note: require is necessary here for synchronous crypto access in Node.js
+	// This will be properly handled by esbuild during bundling
+	// eslint-disable-next-line @typescript-eslint/no-var-requires
+	const crypto = require('crypto') as typeof import('crypto');
+	nodeWebCrypto = crypto.webcrypto;
+} catch {
+	// Not in Node.js environment or crypto not available
+	nodeWebCrypto = undefined;
+}
+
+function getCrypto(): Crypto {
+	// Browser/Electron environment
+	if (typeof window !== 'undefined' && window.crypto) {
+		return window.crypto;
+	}
+
+	// Node.js environment
+	if (nodeWebCrypto) {
+		return nodeWebCrypto as unknown as Crypto;
+	}
+
+	throw new Error('No Web Crypto API available in this environment');
+}
+```
+
+**Step 3: Add eslint-disable comments**
+
+If require() is truly necessary (which it is for sync Node.js module loading in Obsidian), add proper eslint-disable comments with justification.
+
+**Step 4: Test builds**
+
+```bash
+npm run build
+```
+
+**Step 5: Commit require() fixes**
+
+```bash
+git add src/
+git commit -m "fix: improve require() usage with proper typing and comments"
+```
+
+---
+
+## Task 6: Fix Settings UI - Use setHeading() API
+
+**Files:**
+- Modify: `src/settings.ts:130,133,240`
+
+**Step 1: Replace h2 heading**
+
+In `src/settings.ts:130`, replace:
+
+```typescript
+containerEl.createEl('h2', {text: 'MCP Server Settings'});
+```
+
+with:
+
+```typescript
+new Setting(containerEl)
+	.setHeading()
+	.setName('MCP Server Settings');
+```
+
+**Step 2: Replace h3 heading**
+
+In `src/settings.ts:133`, replace:
+
+```typescript
+containerEl.createEl('h3', {text: 'Server Status'});
+```
+
+with:
+
+```typescript
+new Setting(containerEl)
+	.setHeading()
+	.setName('Server Status');
+```
+
+**Step 3: Replace h4 heading**
+
+In `src/settings.ts:240`, replace:
+
+```typescript
+authDetails.createEl('h4', {text: 'MCP Client Configuration', cls: 'mcp-heading'});
+```
+
+with:
+
+```typescript
+new Setting(authDetails)
+	.setHeading()
+	.setName('MCP Client Configuration');
+```
+
+Note: The cls parameter will be lost, but setHeading() provides consistent styling.
+
+**Step 4: Test settings UI**
+
+Build and test in Obsidian to ensure headings render correctly.
+
+**Step 5: Commit settings UI fixes**
+
+```bash
+git add src/settings.ts
+git commit -m "fix: use Setting.setHeading() instead of createElement for headings"
+```
+
+---
+
+## Task 7: Fix notification-history.ts Heading
+
+**Files:**
+- Modify: `src/ui/notification-history.ts:29`
+
+**Step 1: Replace h2 in modal**
+
+In `src/ui/notification-history.ts:29`, the modal already has a title. Check if the h2 is redundant or if it should use a different approach.
+
+Read the file to understand context:
+
+```bash
+cat src/ui/notification-history.ts
+```
+
+**Step 2: Replace with Setting API if in settings context**
+
+If this is in a modal content area and not using Setting API, this might be acceptable. Check the Obsidian API guidelines for modal headings.
+
+For modals, direct createElement is often acceptable. However, if it should follow the same pattern, consider using a div with a class instead:
+
+```typescript
+contentEl.createEl('div', { text: 'MCP Notification History', cls: 'modal-title' });
+```
+
+Or keep it as-is if modals are exempt from the setHeading() requirement.
+
+**Step 3: Verify with Obsidian guidelines**
+
+Check if modal content should use setHeading() or if createElement is acceptable for modals.
+
+**Step 4: Make appropriate changes**
+
+Based on guidelines, either keep as-is or update accordingly.
+
+**Step 5: Commit if changes were made**
+
+```bash
+git add src/ui/notification-history.ts
+git commit -m "fix: update modal heading to follow Obsidian guidelines"
+```
+
+---
+
+## Task 8: Fix UI Text Capitalization - Use Sentence Case
+
+**Files:**
+- Modify: `src/settings.ts` (multiple text strings)
+- Modify: `src/main.ts` (command names, notices)
+- Review all user-facing strings
+
+**Step 1: Fix command names in main.ts**
+
+Commands should use sentence case:
+
+```typescript
+// Line 54
+name: 'Start server',  // Already correct
+
+// Line 62
+name: 'Stop server',  // Already correct
+
+// Line 70
+name: 'Restart server',  // Already correct
+
+// Line 79
+name: 'View notification history',  // Already correct
+```
+
+**Step 2: Fix Notice messages**
+
+Review all Notice calls for proper capitalization:
+
+```typescript
+// Already mostly correct, but verify all instances
+new Notice('MCP Server started on port ${this.settings.port}');
+```
+
+**Step 3: Fix settings.ts strings**
+
+Review all setName() and setDesc() calls:
+
+```typescript
+// Examples that might need fixing:
+.setName('Auto-start server')  // Check if correct
+.setName('Show parameters')    // Check if correct
+.setName('Notification duration')  // Check if correct
+```
+
+Sentence case means: "First word capitalized, rest lowercase unless proper noun"
+
+**Step 4: Create a checklist of all user-facing strings**
+
+```bash
+grep -r "setName\|setDesc\|text:" src/ | grep -v node_modules > /tmp/ui-text-audit.txt
+```
+
+**Step 5: Fix each string to use sentence case**
+
+Review the audit file and fix any Title Case or ALL CAPS strings to use sentence case.
+
+**Step 6: Commit UI text fixes**
+
+```bash
+git add src/
+git commit -m "fix: use sentence case for all UI text"
+```
+
+---
+
+## Task 9: Optional Improvements - Use trashFile() Instead of delete()
+
+**Files:**
+- Modify: `src/tools/note-tools.ts` (delete_note tool)
+- Modify: `src/adapters/file-manager-adapter.ts`
+
+**Step 1: Find all Vault.delete() calls**
+
+```bash
+grep -n "vault.delete\|vault.trash" src/
+```
+
+**Step 2: Replace with FileManager.trashFile()**
+
+In note-tools.ts and file-manager-adapter.ts, replace:
+
+```typescript
+await vault.delete(file);
+```
+
+with:
+
+```typescript
+await app.fileManager.trashFile(file);
+```
+
+This respects the user's "Delete to system trash" setting.
+
+**Step 3: Update adapter interfaces**
+
+If the adapter has a delete method, rename it to trash or add a trash method:
+
+```typescript
+async trashFile(path: string): Promise<void> {
+	const file = this.vault.getAbstractFileByPath(path);
+	if (!file || !(file instanceof TFile)) {
+		throw new Error(`File not found: ${path}`);
+	}
+	await this.app.fileManager.trashFile(file);
+}
+```
+
+**Step 4: Update tool to use trash**
+
+Update the delete_note tool to call the new trash method.
+
+**Step 5: Commit trash improvements**
+
+```bash
+git add src/
+git commit -m "feat: use trashFile to respect user deletion preferences"
+```
+
+---
+
+## Task 10: Clean Up Unused Imports
+
+**Files:**
+- Review all files for unused imports
+
+**Step 1: Run TypeScript unused import check**
+
+```bash
+npx tsc --noEmit --noUnusedLocals 2>&1 | grep "declared but never used"
+```
+
+**Step 2: Remove unused imports from each file**
+
+For each file with unused imports:
+- `MCPPluginSettings` (if unused)
+- `TFile` (if unused)
+- `VaultInfo` (if unused)
+
+**Step 3: Commit unused import cleanup**
+
+```bash
+git add src/
+git commit -m "chore: remove unused imports"
+```
+
+---
+
+## Task 11: Fix Regular Expression Control Characters
+
+**Files:**
+- Search for regex with null bytes or control characters
+
+**Step 1: Find the problematic regex**
+
+```bash
+grep -r "\\x00\|\\x1f" src/
+```
+
+**Step 2: Fix or remove control characters**
+
+The review mentioned "One regex pattern contains unexpected control characters (null and unit separator bytes)". Find and fix this regex.
+
+**Step 3: Test regex patterns**
+
+Ensure all regex patterns are valid and don't contain unintended control characters.
+
+**Step 4: Commit regex fixes**
+
+```bash
+git add src/
+git commit -m "fix: remove control characters from regex pattern"
+```
+
+---
+
+## Task 12: Fix Switch Case Variable Scoping
+
+**Files:**
+- Search for switch statements with variable declarations
+
+**Step 1: Find switch statements**
+
+```bash
+grep -B 2 -A 10 "switch\s*(" src/**/*.ts
+```
+
+**Step 2: Wrap case blocks with braces**
+
+If any case statement declares variables, wrap in braces:
+
+```typescript
+// Before:

+
+```bash
+npx tsc --noEmit --noUnusedLocals --noUnusedParameters 2>&1 | grep "declared but never"
+```
+
+**Step 2: Remove or prefix unused variables**
+
+For each unused variable:
+- Remove if truly unused
+- Prefix with `_` if intentionally unused (e.g., `_error`)
+- Use if it should be used
+
+**Step 3: Commit cleanup**
+
+```bash
+git add src/
+git commit -m "chore: remove unused variables"
+```
+
+---
+
+## Task 14: Final Verification and Testing
+
+**Files:**
+- All source files
+
+**Step 1: Run full build**
+
+```bash
+npm run build
+```
+
+Expected: Clean build with no errors
+
+**Step 2: Run tests**
+
+```bash
+npm test
+```
+
+Expected: All tests pass
+
+**Step 3: Run type check**
+
+```bash
+npx tsc --noEmit
+```
+
+Expected: No errors
+
+**Step 4: Test in Obsidian**
+
+1. Copy build artifacts to test vault

+**Step 3: Commit**
+
+```bash
+git add src/tools/index.ts
+git commit -m "fix: remove eslint-disable directive in tools/index.ts"
+```
+
+---
+
+## Task 6: Fix vault-tools.ts Async Methods
+
+**Files:**
+- Modify: `src/tools/vault-tools.ts:18,63,310,498,925`
+
+**Step 1: Remove async from getVaultInfo (line 18)**
+
+Change from:
+```typescript
+async getVaultInfo(): Promise<CallToolResult> {
+```
+
+To:
+```typescript
+getVaultInfo(): CallToolResult {
+```
+
+**Step 2: Remove async from listNotes (line 63)**

+```
+
+**Step 6: Update callers if any use await on these methods**
+
+Search for any `await this.getVaultInfo()`, `await this.listNotes()`, `await this.exists()`, `await this.resolveWikilink()`, `await this.createFileMetadataWithFrontmatter()` and remove the `await` keyword.
+
+**Step 7: Verify build**
+
+Run: `npm run build`
+Expected: No errors
+
+**Step 8: Commit**
+
+```bash
+git add src/tools/vault-tools.ts

+```
+
+---
+
+## Task 7: Fix notifications.ts ESLint Directives
+
+**Files:**
+- Modify: `src/ui/notifications.ts:10-11,78-79,145-146,179`
+
+**Step 1: Fix interface args type (lines 10-11)**
+
+Change from:
+```typescript
+// eslint-disable-next-line @typescript-eslint/no-explicit-any -- Tool arguments come from JSON-RPC and can be any valid JSON structure

+
+---
+
+## Task 8: Fix crypto-adapter.ts Require Import
+
+**Files:**
+- Modify: `src/utils/crypto-adapter.ts:18-34`
+
+**Step 1: Replace require with dynamic approach**
+
+The challenge here is that require() is used for synchronous access. We need to restructure to use a lazy initialization pattern.
+
+Change the entire Node.js section from:
+```typescript
+// Node.js environment (15+) - uses Web Crypto API standard
+if (typeof global !== 'undefined') {
+    try {
+        // Using require() is necessary for synchronous crypto access in Obsidian desktop plugins
+        // ES6 dynamic imports would create race conditions as crypto must be available synchronously
+        // eslint-disable-next-line @typescript-eslint/no-var-requires -- Synchronous Node.js crypto API access required
+        const nodeCrypto = require('crypto') as typeof import('crypto');
+        if (nodeCrypto?.webcrypto) {
+            return nodeCrypto.webcrypto as unknown as Crypto;
+        }
+    } catch {
+        // Crypto module not available or failed to load
+    }
+}
+```
+
+To (using globalThis.crypto which is available in Node 19+ and Electron):
+```typescript
+// Node.js/Electron environment - globalThis.crypto available in modern runtimes
+if (typeof globalThis !== 'undefined' && globalThis.crypto) {
+    return globalThis.crypto;
+}
+```
+
+**Step 2: Verify build**
+
+Run: `npm run build`
+Expected: No errors
+
+**Step 3: Commit**
+
+```bash
+git add src/utils/crypto-adapter.ts
+git commit -m "fix: use globalThis.crypto instead of require('crypto')"
+```
+
+---
+
+## Task 9: Fix encryption-utils.ts Require Import
+
+**Files:**
+- Modify: `src/utils/encryption-utils.ts:8-18`
+
+**Step 1: Restructure electron import**
+
+Since Electron's safeStorage must be accessed synchronously at module load time, and ES6 dynamic imports are async, we need to use a different approach. In Obsidian plugins running in Electron, we can access electron through the window object.
+
+Change from:
+```typescript
+// Safely import safeStorage - may not be available in all environments
+let safeStorage: ElectronSafeStorage | null = null;
+try {
+    // Using require() is necessary for synchronous access to Electron's safeStorage API in Obsidian desktop plugins
+    // ES6 dynamic imports would create race conditions as this module must be available synchronously
+    // eslint-disable-next-line @typescript-eslint/no-var-requires -- Synchronous Electron API access required for Obsidian plugin
+    const electron = require('electron') as typeof import('electron');
+    safeStorage = electron.safeStorage || null;
+} catch (error) {
+    console.warn('Electron safeStorage not available, API keys will be stored in plaintext');
+}
+```
+
+To:
+```typescript
+// Safely import safeStorage - may not be available in all environments
+let safeStorage: ElectronSafeStorage | null = null;
+try {
+    // Access electron through the global window object in Obsidian's Electron environment
+    // This avoids require() while still getting synchronous access
+    const electronRemote = (window as Window & { require?: (module: string) => typeof import('electron') }).require;
+    if (electronRemote) {
+        const electron = electronRemote('electron');
+        safeStorage = electron.safeStorage || null;
+    }
+} catch {
+    console.warn('Electron safeStorage not available, API keys will be stored in plaintext');
+}
+```
+
+**Step 2: Verify build**
+
+Run: `npm run build`
+Expected: No errors
+
+**Step 3: Commit**
+
+```bash
+git add src/utils/encryption-utils.ts
+git commit -m "fix: use window.require pattern instead of bare require for electron"
+```
+
+---
+
+## Task 10: Fix link-utils.ts Async Method
+
+**Files:**
+- Modify: `src/utils/link-utils.ts:448`
+
+**Step 1: Remove async from validateLinks**
+
+Change from:
+```typescript
+static async validateLinks(
+    vault: IVaultAdapter,
+    metadata: IMetadataCacheAdapter,
+    content: string,
+    sourcePath: string
+): Promise<LinkValidationResult> {
+```
+
+To:
+```typescript
+static validateLinks(
+    vault: IVaultAdapter,
+    metadata: IMetadataCacheAdapter,
+    content: string,
+    sourcePath: string
+): LinkValidationResult {
+```
+
+**Step 2: Update any callers that await this method**
+
+Search for `await LinkUtils.validateLinks` or `await this.validateLinks` and remove the `await`.
+
+**Step 3: Verify build**
+
+Run: `npm run build`
+Expected: No errors
+
+**Step 4: Commit**
+
+```bash
+git add src/utils/link-utils.ts
+git commit -m "fix: remove async from validateLinks method"
+```
+
+---
+
+## Task 11: Final Build and Test
+
+**Step 1: Run full build**
+
+Run: `npm run build`
+Expected: No errors
+
+**Step 2: Run tests**
+
+Run: `npm test`
+Expected: All tests pass
+
+**Step 3: Commit any remaining changes**
+
+```bash
+git status
+# If any uncommitted changes:
+git add -A
+git commit -m "fix: final cleanup for code review issues"
+```

+# Design: Line Numbers by Default in `read_note`
+
+**Date:** 2026-01-31
+**Version:** 1.2.1
+
+## Summary
+
+Change `read_note` to return line-numbered content by default (e.g., `1→First line`) to help AI assistants reference specific locations when discussing notes. Add `withLineNumbers: false` to get raw content.
+
+## Motivation
+
+AI assistants can give much more precise references like "line 42 has a typo" rather than vague "in the section about X". Line numbers make file discussions unambiguous.
+
+## Changes
+
+### 1. Default Behavior Change
+
+```typescript
+// Before
+const withLineNumbers = options?.withLineNumbers ?? false;
+
+// After
+const withLineNumbers = options?.withLineNumbers ?? true;
+```
+
+### 2. Apply to Parsed Path
+
+Currently the `parseFrontmatter: true` path ignores line numbers. Add line numbering to the `content` field (and `contentWithoutFrontmatter`) when enabled.
+
+### 3. Schema Update
+
+Update the tool description to say "Default: true" and clarify opt-out with `withLineNumbers: false`.
+
+## Files to Modify
+
+### `src/tools/note-tools.ts`
+- Line 48: Change default from `false` to `true`
+- Lines 125-155: Add line numbering logic to the `parseFrontmatter` path for `content` and `contentWithoutFrontmatter` fields
+- Add `totalLines` to parsed response when line numbers enabled
+
+### `src/tools/index.ts`
+- Lines 51-54: Update schema description to reflect new default
+
+### `tests/note-tools.test.ts`
+- Update existing tests that expect raw content to either:
+  - Explicitly pass `withLineNumbers: false`, or
+  - Update assertions to expect numbered content
+
+## Response Format Examples
+
+### Before (current default)
+```json
+{
+  "content": "# Title\nSome content",
+  "wordCount": 3,
+  "versionId": "abc123"
+}
+```
+
+### After (new default)
+```json
+{
+  "content": "1→# Title\n2→Some content",
+  "totalLines": 2,
+  "wordCount": 3,
+  "versionId": "abc123"
+}
+```
+
+### Opt-out (`withLineNumbers: false`)
+```json
+{
+  "content": "# Title\nSome content",
+  "wordCount": 3,
+  "versionId": "abc123"
+}
+```
+
+## Breaking Change
+
+This changes the default response format. MCP clients that parse `content` expecting raw text will need to either:
+- Update their parsing to handle line-numbered format
+- Explicitly pass `withLineNumbers: false`
+
+## Version
+
+Bump to 1.2.1.

+
+**Architecture:** Three focused changes: (1) `withLineNumbers` option on `read_note` returns numbered lines using `→` prefix, (2) `force` parameter on `update_sections` makes `ifMatch` required unless explicitly bypassed, (3) always return `versionId` from `read_note`.
+
+**Tech Stack:** TypeScript, Jest, Obsidian API
+
+---
+
+## Task 1: Add `withLineNumbers` Tests
+
+**Files:**
+- Modify: `tests/note-tools.test.ts` (after line ~100, in the `readNote` describe block)
+
+**Step 1: Write the failing tests**
+
+Add these tests in the `describe('readNote', ...)` block:
+
+```typescript
+it('should return numbered lines when withLineNumbers is true', async () => {
+	const mockFile = createMockTFile('test.md', {
+		ctime: 1000,
+		mtime: 2000,
+		size: 100
+	});
+	const content = '# Title\n\nParagraph text\nMore text';
+
+	(PathUtils.resolveFile as jest.Mock).mockReturnValue(mockFile);
+	mockVault.read = jest.fn().mockResolvedValue(content);
+
+	const result = await noteTools.readNote('test.md', { withLineNumbers: true });
+
+	expect(result.isError).toBeUndefined();
+	const parsed = JSON.parse(result.content[0].text);
+	expect(parsed.content).toBe('1→# Title\n2→\n3→Paragraph text\n4→More text');
+	expect(parsed.totalLines).toBe(4);
+	expect(parsed.versionId).toBe('2000-100');
+	expect(parsed.wordCount).toBe(4); // Title Paragraph text More text
+});
+
+it('should return versionId even without withLineNumbers', async () => {
+	const mockFile = createMockTFile('test.md', {
+		ctime: 1000,
+		mtime: 2000,
+		size: 100
+	});
+	const content = '# Test';
+
+	(PathUtils.resolveFile as jest.Mock).mockReturnValue(mockFile);
+	mockVault.read = jest.fn().mockResolvedValue(content);
+
+	const result = await noteTools.readNote('test.md');
+
+	expect(result.isError).toBeUndefined();
+	const parsed = JSON.parse(result.content[0].text);
+	expect(parsed.content).toBe('# Test');
+	expect(parsed.versionId).toBe('2000-100');
+});
+```
+
+**Step 2: Run tests to verify they fail**
+
+Run: `npm test -- --testPathPattern=note-tools.test.ts --testNamePattern="withLineNumbers|versionId even without"`
+Expected: FAIL - `versionId` undefined, content not numbered
+
+**Step 3: Commit failing tests**
+
+```bash
+git add tests/note-tools.test.ts
+git commit -m "test: add failing tests for withLineNumbers and versionId"
+```
+
+---
+
+## Task 2: Implement `withLineNumbers` in `readNote`
+
+**Files:**
+- Modify: `src/tools/note-tools.ts:31-38` (options type)
+- Modify: `src/tools/note-tools.ts:83-99` (implementation)
+
+**Step 1: Update the options type (line 33-37)**
+
+Change from:
+```typescript
+options?: {
+	withFrontmatter?: boolean;
+	withContent?: boolean;
+	parseFrontmatter?: boolean;
+}
+```
+
+To:
+```typescript
+options?: {
+	withFrontmatter?: boolean;
+	withContent?: boolean;
+	parseFrontmatter?: boolean;
+	withLineNumbers?: boolean;
+}
+```
+
+**Step 2: Add withLineNumbers handling (after line 45, before path validation)**
+
+Add this line after the existing option destructuring:
+```typescript
+/* istanbul ignore next */
+const withLineNumbers = options?.withLineNumbers ?? false;
+```
+
+**Step 3: Add numbered content logic (replace lines 83-99)**
+
+Replace the existing `if (!parseFrontmatter)` block with:
+
+```typescript
+// If no special options, return simple content
+if (!parseFrontmatter) {
+	// Compute word count when returning content
+	if (withContent) {
+		const wordCount = ContentUtils.countWords(content);
+		const versionId = VersionUtils.generateVersionId(file);
+
+		// If withLineNumbers, prefix each line with line number
+		if (withLineNumbers) {
+			const lines = content.split('\n');
+			const numberedContent = lines
+				.map((line, idx) => `${idx + 1}→${line}`)
+				.join('\n');
+
+			const result = {
+				content: numberedContent,
+				totalLines: lines.length,
+				versionId,
+				wordCount
+			};
+			return {
+				content: [{ type: "text", text: JSON.stringify(result, null, 2) }]
+			};
+		}
+
+		const result = {
+			content,
+			wordCount,
+			versionId
+		};
+		return {
+			content: [{ type: "text", text: JSON.stringify(result, null, 2) }]
+		};
+	}
+	return {
+		content: [{ type: "text", text: content }]
+	};
+}
+```
+
+**Step 4: Run tests to verify they pass**
+
+Run: `npm test -- --testPathPattern=note-tools.test.ts --testNamePattern="withLineNumbers|versionId even without"`
+Expected: PASS
+
+**Step 5: Run full test suite**
+
+Run: `npm test`
+Expected: All 760+ tests pass
+
+**Step 6: Commit implementation**
+
+```bash
+git add src/tools/note-tools.ts
+git commit -m "feat(read_note): add withLineNumbers option and always return versionId"
+```
+
+---
+
+## Task 3: Update `read_note` Schema
+
+**Files:**
+- Modify: `src/tools/index.ts:39-50` (read_note properties)
+
+**Step 1: Add withLineNumbers to schema**
+
+After the `parseFrontmatter` property (around line 49), add:
+
+```typescript
+withLineNumbers: {
+	type: "boolean",
+	description: "If true, prefix each line with its line number (e.g., '1→content'). Use this when you need to make line-based edits with update_sections. Returns totalLines count and versionId for use with ifMatch parameter. Default: false"
+}
+```
+
+**Step 2: Update tool description (line 31)**
+
+Update the description to mention line numbers:
+
+```typescript
+description: "Read the content of a file from the Obsidian vault with optional frontmatter parsing. Returns versionId for concurrency control. When withLineNumbers is true, prefixes each line with its number (e.g., '1→content') for use with update_sections. Returns word count (excluding frontmatter and Obsidian comments) when content is included. Path must be vault-relative (no leading slash) and include the file extension. Use list() first if you're unsure of the exact path.",
+```
+
+**Step 3: Verify build passes**
+
+Run: `npm run build`
+Expected: Build succeeds with no type errors
+
+**Step 4: Commit schema update**
+
+```bash
+git add src/tools/index.ts
+git commit -m "docs(read_note): add withLineNumbers to tool schema"
+```
+
+---
+
+## Task 4: Add `force` Parameter Tests for `updateSections`
+
+**Files:**
+- Modify: `tests/note-tools.test.ts` (after line ~960, in the `updateSections` describe block)
+
+**Step 1: Write failing tests**
+
+Add these tests in the `describe('updateSections', ...)` block:
+
+```typescript
+it('should return error when ifMatch not provided and force not set', async () => {
+	const mockFile = createMockTFile('test.md');
+	(PathUtils.resolveFile as jest.Mock).mockReturnValue(mockFile);
+
+	const result = await noteTools.updateSections('test.md', [
+		{ startLine: 1, endLine: 1, content: 'New' }
+	]);
+
+	expect(result.isError).toBe(true);
+	const parsed = JSON.parse(result.content[0].text);
+	expect(parsed.error).toBe('Version check required');
+	expect(parsed.message).toContain('ifMatch parameter is required');
+	expect(mockVault.modify).not.toHaveBeenCalled();
+});
+
+it('should proceed without ifMatch when force is true', async () => {
+	const mockFile = createMockTFile('test.md', {
+		ctime: 1000,
+		mtime: 2000,
+		size: 100
+	});
+	const content = 'Line 1\nLine 2';
+
+	(PathUtils.resolveFile as jest.Mock).mockReturnValue(mockFile);
+	mockVault.read = jest.fn().mockResolvedValue(content);
+	mockVault.modify = jest.fn().mockResolvedValue(undefined);
+
+	const result = await noteTools.updateSections(
+		'test.md',
+		[{ startLine: 1, endLine: 1, content: 'New Line 1' }],
+		undefined, // no ifMatch

+		ctime: 1000,
+		mtime: 2000,
+		size: 100
+	});
+	const content = 'Line 1\nLine 2';
+
+	(PathUtils.resolveFile as jest.Mock).mockReturnValue(mockFile);
+	mockVault.read = jest.fn().mockResolvedValue(content);
+	mockVault.modify = jest.fn().mockResolvedValue(undefined);
+
+	const result = await noteTools.updateSections(
+		'test.md',
+		[{ startLine: 1, endLine: 1, content: 'New Line 1' }],
+		'2000-100' // valid ifMatch
+	);
+
+	expect(result.isError).toBeUndefined();
+	expect(mockVault.modify).toHaveBeenCalled();
+});
+```
+
+**Step 2: Run tests to verify they fail**
+
+Run: `npm test -- --testPathPattern=note-tools.test.ts --testNamePattern="ifMatch not provided|force is true|valid ifMatch without force"`
+Expected: FAIL - first test expects error but gets success, second test has wrong arity
+
+**Step 3: Commit failing tests**
+
+```bash
+git add tests/note-tools.test.ts
+git commit -m "test: add failing tests for updateSections force parameter"
+```
+
+---
+
+## Task 5: Implement `force` Parameter in `updateSections`
+
+**Files:**
+- Modify: `src/tools/note-tools.ts:880-907` (method signature and validation)
+
+**Step 1: Update method signature (lines 880-885)**
+
+Change from:
+```typescript
+async updateSections(
+	path: string,
+	edits: SectionEdit[],
+	ifMatch?: string,
+	validateLinks: boolean = true
+): Promise<CallToolResult> {
+```
+
+To:
+```typescript
+async updateSections(
+	path: string,
+	edits: SectionEdit[],
+	ifMatch?: string,
+	validateLinks: boolean = true,
+	force: boolean = false
+): Promise<CallToolResult> {
+```
+
+**Step 2: Add ifMatch requirement check (after line 907, after edits validation)**
+
+Insert after the "No edits provided" check:
+
+```typescript
+// Require ifMatch unless force is true
+if (!ifMatch && !force) {
+	return {
+		content: [{
+			type: "text",
+			text: JSON.stringify({
+				error: 'Version check required',
+				message: 'The ifMatch parameter is required to prevent overwriting concurrent changes. First call read_note with withLineNumbers:true to get the versionId, then pass it as ifMatch. To bypass this check, set force:true (not recommended).'
+			}, null, 2)
+		}],
+		isError: true
+	};
+}
+```
+
+**Step 3: Run tests to verify they pass**
+
+Run: `npm test -- --testPathPattern=note-tools.test.ts --testNamePattern="ifMatch not provided|force is true|valid ifMatch without force"`
+Expected: PASS
+
+**Step 4: Run full test suite**
+
+Run: `npm test`
+Expected: Some tests may fail (existing tests that don't pass ifMatch)
+
+**Step 5: Fix existing tests that now fail**
+
+Update existing `updateSections` tests to either:
+- Pass a valid `ifMatch` value, OR
+- Pass `force: true`
+
+For the "should update sections successfully" test (around line 882), update to use force:
+
+```typescript
+const result = await noteTools.updateSections('test.md', [
+	{ startLine: 2, endLine: 3, content: 'New Line 2\nNew Line 3' }
+], undefined, true, true); // validateLinks=true, force=true
+```
+
+Apply similar fixes to other affected tests in the `updateSections` block.
+
+**Step 6: Run full test suite again**
+
+Run: `npm test`
+Expected: All tests pass
+
+**Step 7: Commit implementation**
+
+```bash
+git add src/tools/note-tools.ts tests/note-tools.test.ts
+git commit -m "feat(update_sections): require ifMatch with force opt-out"
+```
+
+---
+
+## Task 6: Update `update_sections` Schema and Call Site
+
+**Files:**
+- Modify: `src/tools/index.ts:184-194` (update_sections schema)
+- Modify: `src/tools/index.ts:529-537` (call site)
+
+**Step 1: Update ifMatch description (line 184-187)**
+
+Change from:
+```typescript
+ifMatch: {
+	type: "string",
+	description: "Optional ETag/versionId for concurrency control. If provided, update only proceeds if file hasn't been modified. Get versionId from read operations. Prevents conflicting edits in concurrent scenarios."
+},
+```
+
+To:
+```typescript
+ifMatch: {
+	type: "string",
+	description: "Required: ETag/versionId for concurrency control. Get this from read_note response (always included). Update only proceeds if file hasn't changed since read. Omit only with force:true."
+},
+```
+
+**Step 2: Add force property (after validateLinks, around line 191)**
+
+Add:
+```typescript
+force: {
+	type: "boolean",
+	description: "If true, skip version check and apply edits without ifMatch. Use only when you intentionally want to overwrite without checking for concurrent changes. Not recommended. Default: false"
+}
+```
+
+**Step 3: Update call site (lines 529-537)**
+
+Change from:
+```typescript
+case "update_sections": {
+	const a = args as { path: string; edits: Array<{ startLine: number; endLine: number; content: string }>; ifMatch?: string; validateLinks?: boolean };
+	result = await this.noteTools.updateSections(
+		a.path,
+		a.edits,
+		a.ifMatch,
+		a.validateLinks ?? true
+	);
+	break;
+}
+```
+
+To:
+```typescript
+case "update_sections": {
+	const a = args as { path: string; edits: Array<{ startLine: number; endLine: number; content: string }>; ifMatch?: string; validateLinks?: boolean; force?: boolean };
+	result = await this.noteTools.updateSections(
+		a.path,
+		a.edits,
+		a.ifMatch,
+		a.validateLinks ?? true,
+		a.force ?? false
+	);
+	break;
+}
+```
+
+**Step 4: Verify build passes**
+
+Run: `npm run build`
+Expected: Build succeeds
+
+**Step 5: Run full test suite**
+
+Run: `npm test`
+Expected: All tests pass
+
+**Step 6: Commit schema and call site updates**
+
+```bash
+git add src/tools/index.ts
+git commit -m "docs(update_sections): update schema for required ifMatch and force opt-out"
+```
+
+---
+
+## Task 7: Final Verification
+
+**Step 1: Run full test suite with coverage**
+
+Run: `npm run test:coverage`
+Expected: All tests pass, coverage maintained
+
+**Step 2: Build for production**
+
+Run: `npm run build`
+Expected: Build succeeds with no errors
+
+**Step 3: Manual verification checklist**
+
+Verify these scenarios work correctly:
+
+1. `read_note` without options → returns `content`, `wordCount`, `versionId`
+2. `read_note` with `withLineNumbers: true` → returns numbered content, `totalLines`, `versionId`
+3. `update_sections` without `ifMatch` → returns "Version check required" error
+4. `update_sections` with `force: true` → proceeds without version check
+5. `update_sections` with valid `ifMatch` → proceeds normally
+6. `update_sections` with stale `ifMatch` → returns version mismatch error
+
+**Step 4: Create summary commit**
+
+```bash
+git log --oneline -6
+```
+
+Verify commit history looks clean and logical.

+# Remote IP access for MCP server
+
+Date: 2026-02-06
+
+## Problem
+
+The MCP server is hardcoded to localhost-only access (bind address, CORS, host header validation). This prevents use cases where Obsidian runs in a Docker container or remote machine and MCP clients connect over a Tailscale VPN or other private network.
+
+## Design
+
+### New setting: `allowedIPs`
+
+A comma-separated string of IPs and CIDR ranges. Default: `""` (empty).
+
+- When empty: server behaves exactly as today (binds to `127.0.0.1`, localhost-only)
+- When populated: server binds to `0.0.0.0` and allows connections from listed IPs/CIDRs
+- Localhost (`127.0.0.1`) is always implicitly allowed regardless of the setting
+- Examples: `100.64.0.0/10`, `192.168.1.50`, `10.0.0.0/8`
+
+### Middleware changes (src/server/middleware.ts)
+
+Three layers are updated:
+
+1. **Source IP validation (new)** - Checks `req.socket.remoteAddress` against the allow-list before auth. Rejects connections from unlisted IPs with 403. Localhost always passes.
+
+2. **CORS policy update** - Extends the origin check to allow origins whose hostname matches the allow-list, in addition to the existing localhost regex.
+
+3. **Host header validation update** - Extends to accept Host headers matching allowed IPs, in addition to localhost.
+
+All three use a shared `isIPAllowed()` utility.
+
+### Server bind (src/server/mcp-server.ts)
+
+The `start()` method computes bind address dynamically:
+- `allowedIPs` non-empty (trimmed) -> bind `0.0.0.0`
+- `allowedIPs` empty -> bind `127.0.0.1` (current behavior)
+
+### Network utilities (src/utils/network-utils.ts)
+
+New file (~40 lines) exporting:
+
+- `parseAllowedIPs(setting: string): AllowedIPEntry[]` - Parses comma-separated string into structured list of individual IPs and CIDR ranges
+- `isIPAllowed(ip: string, allowList: AllowedIPEntry[]): boolean` - Checks if an IP matches any entry. Handles IPv4-mapped IPv6 addresses (`::ffff:x.x.x.x`) that Node.js uses for `req.socket.remoteAddress`
+
+CIDR matching is standard bit arithmetic, no external dependencies needed.
+
+### Settings UI (src/settings.ts)
+
+New text field below the Port setting:
+- Name: "Allowed IPs"
+- Description: "Comma-separated IPs or CIDR ranges allowed to connect (e.g., 100.64.0.0/10, 192.168.1.50). Leave empty for localhost only. Restart required."
+- Placeholder: `100.64.0.0/10, 192.168.1.0/24`
+- Shows restart warning when changed while server is running
+- Shows security note when non-empty: "Server is accessible from non-localhost IPs. Ensure your API key is kept secure."
+
+Status display updates to show actual bind address (`0.0.0.0` vs `127.0.0.1`).
+
+Generated client configs (Windsurf/Claude Code) stay as `127.0.0.1` - users adjust manually for remote access.
+
+### Settings type (src/types/settings-types.ts)
+
+Add `allowedIPs: string` to `MCPServerSettings` with default `""`.
+
+## Security model
+
+- **Auth is still mandatory.** IP allow-list is defense-in-depth, not a replacement for Bearer token authentication.
+- **Localhost always allowed.** Cannot accidentally lock out local access.
+- **Empty default = current behavior.** Zero-change upgrade for existing users. Feature is opt-in.
+- **Three-layer validation:** Source IP check + CORS + Host header validation + Bearer auth.
+
+## Testing
+
+New file `tests/network-utils.test.ts`:
+- Individual IP match/mismatch
+- CIDR range matching (e.g., `100.64.0.0/10` matches `100.100.1.1`)
+- IPv4-mapped IPv6 handling (`::ffff:192.168.1.1`)
+- Edge cases: empty string, malformed entries, extra whitespace
+- Localhost always allowed regardless of list contents
+
+## Files changed
+
+1. `src/types/settings-types.ts` - Add `allowedIPs` field
+2. `src/utils/network-utils.ts` - New file: CIDR parsing + IP matching
+3. `src/server/middleware.ts` - Update CORS, host validation, add source IP check
+4. `src/server/mcp-server.ts` - Dynamic bind address
+5. `src/settings.ts` - New text field + security note
+6. `tests/network-utils.test.ts` - New test file

+# Plan: Fix update_sections Line Number Issue via MCP Server Changes
+
+## Problem Analysis
+
+When using `update_sections`, line number errors occur because:
+
+1. **`read_note` doesn't return line numbers** - Returns content as a string, no line mapping
+2. **`ifMatch` is optional** - No enforcement of version checking before edits
+3. **`versionId` inconsistent** - Only returned when `parseFrontmatter: true`
+
+### Root Cause
+
+The `Read` tool shows line numbers (e.g., `1→content`) but `read_note` does not. When using `read_note` and later calling `update_sections`, line numbers are guessed based on stale content.
+
+---
+
+## Proposed Changes
+
+### Change 1: Add `withLineNumbers` Option to `read_note`
+
+**File:** `src/tools/note-tools.ts`
+
+**Current behavior:** Returns `{ content: "...", wordCount: N }`
+
+**New behavior with `withLineNumbers: true`:** Returns numbered lines using `→` prefix:
+
+```json
+{
+  "content": "1→---\n2→title: Example\n3→---\n4→\n5→## Overview\n6→Some text here",
+  "totalLines": 6,
+  "versionId": "abc123",
+  "wordCount": 42
+}
+```
+
+**Implementation (add after existing options handling):**
+
+```typescript
+// If withLineNumbers requested, prefix each line with line number
+if (options?.withLineNumbers && withContent) {
+  const lines = content.split('\n');
+  const numberedContent = lines
+    .map((line, idx) => `${idx + 1}→${line}`)
+    .join('\n');
+
+  const result = {
+    content: numberedContent,
+    totalLines: lines.length,
+    versionId: VersionUtils.generateVersionId(file),
+    wordCount: ContentUtils.countWords(content)
+  };
+  return {
+    content: [{ type: "text", text: JSON.stringify(result, null, 2) }]
+  };
+}
+```
+
+**Schema update (in `index.ts`):**
+
+```typescript
+withLineNumbers: {
+  type: "boolean",
+  description: "If true, prefix each line with its line number (e.g., '1→content'). Use this when you need to make line-based edits with update_sections. Returns totalLines count and versionId for use with ifMatch parameter."
+}
+```
+
+---
+
+### Change 2: Require `ifMatch` for `update_sections`
+
+**File:** `src/tools/note-tools.ts`
+
+**Current behavior:** `ifMatch` is optional - edits proceed without version check.
+
+**New behavior:** `ifMatch` is required unless `force: true` is passed.
+
+**Method signature change:**
+
+```typescript
+async updateSections(
+  path: string,
+  edits: SectionEdit[],
+  ifMatch?: string,        // Still optional in signature
+  validateLinks: boolean = true,
+  force?: boolean          // NEW: explicit opt-out
+): Promise<CallToolResult>
+```
+
+**Validation logic (early in method, after path/edits validation):**
+
+```typescript
+// Require ifMatch unless force is true
+if (!ifMatch && !force) {
+  return {
+    content: [{
+      type: "text",
+      text: JSON.stringify({
+        error: 'Version check required',
+        message: 'The ifMatch parameter is required to prevent overwriting concurrent changes. First call read_note with withLineNumbers:true to get the versionId, then pass it as ifMatch. To bypass this check, set force:true (not recommended).'
+      }, null, 2)
+    }],
+    isError: true
+  };
+}
+```
+
+**Schema update (in `index.ts`):**
+
+```typescript
+ifMatch: {
+  type: "string",
+  description: "Required: ETag/versionId for concurrency control. Get this from read_note response. Update only proceeds if file hasn't changed since read. Omit only with force:true."
+},
+force: {
+  type: "boolean",
+  description: "If true, skip version check and apply edits without ifMatch. Use only when you intentionally want to overwrite without checking for concurrent changes. Default: false"
+}
+```
+
+**Note:** Keep `required: ["path", "edits"]` in schema - we enforce `ifMatch` in code to provide a helpful error message.
+
+---
+
+### Change 3: Always Return `versionId` from `read_note`
+
+**File:** `src/tools/note-tools.ts`
+
+**Current behavior:** Only returns `versionId` when `parseFrontmatter: true`.
+
+**New behavior:** Always include `versionId` in the response.
+
+**Current code (around line 88):**
+
+```typescript
+const result = {
+  content,
+  wordCount
+};
+```
+
+**Updated code:**
+
+```typescript
+const result = {
+  content,
+  wordCount,
+  versionId: VersionUtils.generateVersionId(file)
+};
+```
+
+---
+
+## Files to Modify
+
+| File | Changes |
+|------|---------|
+| `src/tools/note-tools.ts` | Add `withLineNumbers`, add `force` parameter, always return `versionId` |
+| `src/tools/index.ts` | Update schemas for `read_note` and `update_sections` |
+
+---
+
+## Implementation Steps
+
+1. **Modify `readNote`** in `note-tools.ts`:
+   - Add `withLineNumbers` option handling
+   - Always return `versionId` when returning content
+
+2. **Modify `updateSections`** in `note-tools.ts`:
+   - Add `force` parameter
+   - Add validation requiring `ifMatch` unless `force: true`
+
+3. **Update tool schemas** in `index.ts`:
+   - Add `withLineNumbers` property to `read_note` schema
+   - Add `force` property to `update_sections` schema
+   - Update `ifMatch` description to indicate it's required
+
+4. **Update call site** in `index.ts`:
+   - Pass `force` parameter through to `updateSections`
+
+5. **Write tests** for new behaviors
+
+6. **Build and test** in Obsidian
+
+---
+
+## Verification
+
+1. **`read_note` with `withLineNumbers: true`** → returns numbered content, `totalLines`, `versionId`
+2. **`read_note` without options** → returns content with `versionId` (new behavior)
+3. **`update_sections` without `ifMatch`** → returns error with helpful message
+4. **`update_sections` with `force: true`** → proceeds without version check
+5. **`update_sections` with valid `ifMatch`** → proceeds normally
+6. **`update_sections` with stale `ifMatch`** → returns version mismatch error
+
+---
+
+## Breaking Change
+
+**Impact:** Callers that omit `ifMatch` from `update_sections` will receive an error unless they explicitly pass `force: true`.
+
+**Mitigation:** The error message explains how to fix the issue and mentions the `force` option for those who intentionally want to skip version checking.
