MCP Notes Tools

MCP Notes Tools is an Obsidian desktop plugin that exposes local MCP tools for a project-specific vault. It lets an MCP client search notes, read a selected note, and request a confirmed append-only change note.

Features

• obsidian_search_notes: searches note title, vault-relative path, and note body content.
• obsidian_get_note: returns the full current content for one selected markdown note.
• obsidian_append_change_note: asks for confirmation, then appends text under a Change notes section with a timestamp.

Every note reference includes both title and vault-relative path. Attachments, binary files, and plugin configuration files are out of scope.

Privacy and Safety

The plugin operates locally on the active Obsidian vault. It does not send note content, filenames, metadata, or user identifiers to external services.

Append requests always require per-write confirmation in Obsidian before any note is changed. Existing note content is preserved before the appended Change notes entry.

Desktop Only

This plugin is desktop-only because local MCP serving depends on desktop runtime capabilities that are not available in Obsidian mobile.

Local MCP Endpoint

Enable the local MCP server in Settings -> MCP Notes Tools. The settings tab shows the endpoint, which defaults to:

http://127.0.0.1:39399/mcp

Configure your MCP client to connect to that local endpoint while Obsidian is running and the plugin is enabled.

The plugin also exposes a vault-specific alias for clients that need to disambiguate project vaults:

http://127.0.0.1:39399/vaults/<vault-slug>/mcp

The alias is only a routing label for the current Obsidian vault. A mismatched slug is rejected; one plugin instance cannot query other vaults.

Development

Install dependencies:

npm install

Run the development build:

npm run dev

Run validation checks:

npm run lint
npm run build

Reload Obsidian after changing manifest.json. Reload the plugin after source changes so the generated main.js is loaded.

Release Artifacts

Required release files:

• manifest.json
• main.js
• styles.css if styles are used

Do not edit main.js manually. Generate it with npm run build.
