All notable changes to the Obsidian MCP Server plugin will be documented in this file.
The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.
[1.3.0] - 2026-02-06
Added
- Remote IP access: New
allowedIPssetting accepts comma-separated IPs and CIDR ranges (e.g.,100.64.0.0/10for Tailscale) to allow non-localhost connections- Server automatically binds to
0.0.0.0when remote IPs are configured, otherwise stays on127.0.0.1 - 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-utilsmodule with CIDR parsing and IP matching (no external dependencies) - Security warning displayed in settings when remote access is enabled
- Server automatically binds to
[1.2.0] - 2026-01-31
Added
-
Line Numbers for
read_note: NewwithLineNumbersoption prefixes each line with its 1-indexed line number (e.g.,1→# Title,2→Content)- Returns
totalLinescount for easy reference - Designed for use with
update_sectionsto ensure accurate line-based edits - Example:
read_note("note.md", { withLineNumbers: true })returns numbered content
- Returns
-
Force Parameter for
update_sections: Newforceparameter allows bypassing the version check- Use
force: trueto skip theifMatchrequirement (not recommended for normal use) - Intended for scenarios where you intentionally want to overwrite without checking
- Use
Changed
read_noteAlways ReturnsversionId: The response now always includesversionIdfor concurrency control- Previously only returned when
parseFrontmatter: true - Enables safe
update_sectionsworkflows by providing the ETag upfront
- Previously only returned when
Breaking Changes
update_sectionsNow RequiresifMatch: TheifMatchparameter is now required by default- Prevents accidental overwrites when file content has changed since reading
- Get
versionIdfromread_noteresponse and pass it asifMatch - 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.tswhereargs.recursivecould produce[object Object]when stringified- Added explicit
String()coercion for unknown types in template literals

-
File Deletion API: Replaced
Vault.trash()withFileManager.trashFile()per Obsidian guidelines- All file deletions now respect user's configured deletion preference (system trash or
.trash/folder) - Removed unused
trash()method fromIVaultAdapterinterface andVaultAdapterclass - Both soft and regular delete operations now use the same user-preferred deletion method
- All file deletions now respect user's configured deletion preference (system trash or
Changed
delete_notedestination field now returns'trash'instead of.trash/{filename}since actual location depends on user settings

[1.1.0] - 2025-10-30
Added
- Word Count:
create_note,update_note, andupdate_sectionsnow 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.)
- Excludes YAML frontmatter and Obsidian comments (
- Link Validation:
create_note,update_note, andupdate_sectionsnow 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: falseparameter for performance-critical operations
- Validates basic wikilinks (
- Word Count for Read Operations: Extended word count support to read operations
read_notenow automatically includeswordCountwhen returning content (withwithContentorparseFrontmatteroptions)statsupports optionalincludeWordCountparameter to compute word count (with performance warning)listsupports optionalincludeWordCountparameter 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

[1.0.1] - 2025-10-28
Fixed
- Updated config path examples from
.obsidian/**totemplates/**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()withapp.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
