Obsidian MCP Extended

This is a fork of smithery-ai/mcp-obsidian with added write support functionality.

This connector allows Claude Desktop, Cursor, or any MCP client to read, search, write to, and now delete notes from any directory containing Markdown notes (such as an Obsidian vault).

What's New in This Fork

This fork adds critical new features to the original MCP server:

write_note functionality: Allows AI assistants to create and update notes in your Obsidian vault
delete_note functionality: Allows AI assistants to delete notes from your Obsidian vault
Perfect for enabling long-term memory for your AI assistants
Maintains all the security features of the original implementation
Full backwards compatibility with the original project

Installation

Make sure Claude Desktop/Cursor and npm are installed.

Installing from Source (Recommended for write support)

To install this enhanced version with write support:

git clone https://github.com/Zafnok/mcp-obsidian-extended.git
cd mcp-obsidian-extended
npm install
npm run build

Then configure Cursor or Claude to use this version by pointing to the local build:

Open Cursor Settings (Cmd+Shift+J) or Claude Desktop settings
Go to the MCP tab
Add a new MCP server with:
- Name: Obsidian Extended
- Type: stdio
- Command: node /path/to/mcp-obsidian-extended/dist/index.js /path/to/your/vault

Installing Original Version via Smithery

To install the original Obsidian Model Context Protocol (without write support):

npx @smithery/cli install mcp-obsidian --client claude

Available Tools

This MCP server provides the following tools:

1. `read_notes`

Read the contents of multiple notes. Each note's content is returned with its path as a reference.

2. `search_notes`

Searches for a note by its name. The search is case-insensitive and matches partial names. Queries can also be a valid regex.

3. `write_note` (New in this fork!)

Write content to a note in the Obsidian vault. If the note doesn't exist, it will be created by default.

Example usage:

{
  "path": "folder/new-note.md",
  "content": "# My New Note\n\nThis is the content of my note.",
  "createIfNotExists": true
}

4. `delete_note` (New in this fork!)

Delete a note from the Obsidian vault. Returns success or error message.

Example usage:

{
  "path": "folder/note-to-delete.md"
}
