  • Returns existence status, kind (file/directory), and full metadata
  • Includes size, dates, child count, etc.
  • More detailed than exists() but slightly slower
• exists - Quickly check if a file or folder exists
  • Fast path validation without fetching full metadata
  • Returns existence status and kind only
  • Optimized for quick existence checks

Type Definitions (src/types/mcp-types.ts)

• StatResult - Structured result for stat operations (path, exists, kind, metadata)
• ExistsResult - Structured result for exists operations (path, exists, kind)

Implementation (src/tools/vault-tools.ts)

• stat(path) method - Comprehensive path metadata retrieval
• exists(path) method - Fast existence checking
• Both methods use PathUtils for consistent path normalization
• Both methods validate paths and return structured JSON

Tool Registry (src/tools/index.ts)

• Registered stat and exists tools with complete schemas
• Added call handlers for both new tools
• Comprehensive descriptions for AI agent usage

Use Cases

stat Tool:

• Verify a path exists before operations
• Get detailed file/folder information
• Check file sizes and modification dates
• Determine if a path is a file or directory

exists Tool:

• Quick existence checks before create operations
• Validate paths in batch operations
• Fast pre-flight checks
• Minimal overhead for simple validation

Example Responses

stat (file exists):

{
  "path": "folder/note.md",
  "exists": true,
  "kind": "file",
  "metadata": {
    "kind": "file",
    "name": "note.md",
    "path": "folder/note.md",
    "extension": "md",
    "size": 1234,
    "modified": 1697500800000,
    "created": 1697400000000
  }
}

exists (folder exists):

{
  "path": "projects",
  "exists": true,
  "kind": "directory"
}

stat (path doesn't exist):

{
  "path": "missing/file.md",
  "exists": false
}

[2.0.0] - 2025-10-16

🔧 Phase 2.1: Post-Testing Fixes

Based on testing feedback, the following improvements were made to the Phase 2 implementation:

Fixed

Root Listing Semantics (src/tools/vault-tools.ts)

• Clarified root path handling: undefined, "" (empty string), or "." all represent the vault root
• Root listing now correctly returns direct children only (excludes vault root itself)
• Added explicit check to skip vault root folder (path === '')
• Improved code clarity with explicit isRootPath check

Alphabetical Sorting

• Fixed sorting to be case-insensitive for stable, consistent ordering
• Directories are sorted alphabetically (case-insensitive), then files alphabetically (case-insensitive)
• Ensures predictable order for names like "CTP Lancaster" and "Construction Game"

Directory Metadata

• Added logic to populate modified timestamp from filesystem if available
• Falls back to 0 when filesystem metadata is not available (which is typical for directories)
• Added documentation explaining when modified may be 0
• Note: Obsidian's TFolder API doesn't include stat property, so directories will typically show modified: 0

Documentation (src/tools/index.ts)

• Updated list_notes description to document root path options ("" or ".")
• Added explicit warning that leading slashes (e.g., "/" or "/folder") are invalid
• Clarified that sorting is case-insensitive within each group
• Added note that only direct children are returned (non-recursive)

Technical Details

Root Path Handling:

// All of these list the vault root:
list_notes()              // undefined
list_notes({ path: "" })  // empty string
list_notes({ path: "." }) // dot

Invalid Paths:

// These will error:
list_notes({ path: "/" })       // leading slash
list_notes({ path: "/folder" }) // leading slash

🔄 Phase 2: API Unification & Typed Results (BREAKING CHANGES)

This release introduces structured, typed responses for all tools and unifies parameter naming. Note: This is a breaking change as backwards compatibility is not maintained.

Added

Typed Result Interfaces (src/types/mcp-types.ts)

• FileMetadata - Structured file information (kind, name, path, extension, size, modified, created)
• DirectoryMetadata - Structured directory information (kind, name, path, childrenCount, modified)
• VaultInfo - Structured vault information (name, path, totalFiles, totalFolders, markdownFiles, totalSize)
• SearchMatch - Detailed search match information (path, line, column, snippet, matchRanges)
• SearchResult - Comprehensive search results (query, matches, totalMatches, filesSearched, filesWithMatches)
• ItemKind - Type union for "file" | "directory"

Enhanced Tool Responses

• All tools now return structured JSON instead of plain text
• Consistent response format across all operations
• Machine-readable data for better integration

Changed

list_notes Tool (BREAKING)

• Parameter: folder → path (breaking change - folder parameter removed)
• Response: Now returns array of FileMetadata and DirectoryMetadata objects
• Behavior: Lists direct children only (non-recursive)
• Includes both files AND directories (not just markdown files)
• Sorted: directories first, then files, alphabetically
• Each item includes detailed metadata (size, dates, child count)

search_notes Tool (BREAKING)

• Response: Now returns structured SearchResult object
• Includes line numbers, column positions, and context snippets
• Provides match ranges for highlighting
• Tracks files searched and files with matches
• Filename matches indicated with line: 0

get_vault_info Tool (BREAKING)

• Response: Now returns structured VaultInfo object
• Added: totalFolders count
• Added: totalSize in bytes
• Renamed: rootPath → path

Tool Descriptions

• Updated all tool descriptions to reflect structured JSON responses
• Clarified return value formats
• Removed deprecated folder parameter

Implementation Details

src/tools/vault-tools.ts

• searchNotes() - Complete rewrite with line-by-line search and snippet extraction
• getVaultInfo() - Added folder counting and size calculation
• listNotes() - Rewritten to return structured metadata for files and directories
• Added createFileMetadata() helper method
• Added createDirectoryMetadata() helper method

src/tools/index.ts

• Updated tool schemas to use path parameter only
• Updated tool descriptions to document structured responses
• Modified callTool() to pass path parameter

Migration Guide

Before (v1.x):

// list_notes returned plain text
"Found 3 notes:\nfile1.md\nfile2.md\nfile3.md"

// search_notes returned plain text
"Found 2 notes:\npath/to/note1.md\npath/to/note2.md"

// get_vault_info returned simple object
{ "name": "MyVault", "totalFiles": 100, "markdownFiles": 80, "rootPath": "/path" }

After (v2.x):

// list_notes returns structured array
[
  { "kind": "directory", "name": "folder1", "path": "folder1", "childrenCount": 5, "modified": 0 },
  { "kind": "file", "name": "note.md", "path": "note.md", "extension": "md", "size": 1024, "modified": 1697472000000, "created": 1697472000000 }
]

// search_notes returns detailed matches
{
  "query": "TODO",
  "matches": [
    { "path": "note.md", "line": 5, "column": 10, "snippet": "...context around TODO item...", "matchRanges": [{ "start": 15, "end": 19 }] }
  ],
  "totalMatches": 1,
  "filesSearched": 100,
  "filesWithMatches": 1
}

// get_vault_info returns comprehensive info
{ "name": "MyVault", "path": "/path", "totalFiles": 100, "totalFolders": 20, "markdownFiles": 80, "totalSize": 5242880 }

Benefits

• Machine-readable: Structured JSON for easy parsing and integration
• Detailed metadata: Rich information for each file and directory
• Search precision: Line numbers, columns, and snippets for exact match location
• Consistency: Unified response format across all tools
• Type safety: Well-defined TypeScript interfaces

[1.2.0] - 2025-10-16

Comprehensive Test Suite (tests/parent-folder-detection.test.ts)

• 15 test cases covering all scenarios
• Tests explicit parent folder detection
• Tests recursive folder creation
• Tests error handling and edge cases
• Validates error message content

Changed

• createNote() signature: added optional createParents parameter

🔐 Enhanced Authentication & Security (Phase 1.5)

This update significantly improves authentication security and user experience with automatic key generation and enhanced UI.

Added

Automatic API Key Generation (src/utils/auth-utils.ts)

• generateApiKey() - Cryptographically secure random key generation (32 characters)
• validateApiKey() - API key validation with strength requirements
• Uses crypto.getRandomValues() for secure randomness
