Obsidian MCP Server

An MCP (Model Context Protocol) server that enables AI assistants to interact with Obsidian vaults, providing tools for reading, creating, editing and managing notes and tags.

Warning!!!

This MCP has read and write access (if you allow it). Please. PLEASE backup your Obsidian vault prior to using obsidian-mcp to manage your notes. I recommend using git, but any backup method will work. These tools have been tested, but not thoroughly, and this MCP is in active development.

Features

Read and search notes in your vault
Create new notes and directories
Edit existing notes
Move and delete notes
Manage tags (add, remove, rename)
Search vault contents

Requirements

Node.js 20 or higher (might work on lower, but I haven't tested it)
An Obsidian vault

Install

Installing Manually

Add to your Claude Desktop configuration:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

{
    "mcpServers": {
        "obsidian": {
            "command": "npx",
            "args": ["-y", "obsidian-mcp", "/path/to/your/vault", "/path/to/your/vault2"]
        }
    }
}

Replace /path/to/your/vault with the absolute path to your Obsidian vault. For example:

MacOS/Linux:

"/Users/username/Documents/MyVault"

Windows:

"C:\\Users\\username\\Documents\\MyVault"

Restart Claude for Desktop after saving the configuration. You should see the hammer icon appear, indicating the server is connected.

If you have connection issues, check the logs at:

MacOS: ~/Library/Logs/Claude/mcp*.log
Windows: %APPDATA%\Claude\logs\mcp*.log
