Obsidian MCP REST Server

An MCP (Model Context Protocol) server implementation that provides access to Obsidian vaults through a local REST API. This server allows AI assistants to interact with Obsidian notes and manage vault content through a standardized interface.

Features

• Access Obsidian vault contents through MCP
• Read and write notes
• List vault contents
• Search functionality
• Secure local REST API integration
• Compatible with Claude Desktop and other AI assistants

Prerequisites

• Node.js 16 or higher
• Obsidian with Local REST API plugin installed and configured
• An Obsidian vault with Local REST API enabled

Installation

Install the package globally:

npm install -g PublikPrinciple/obsidian-mcp-rest

Or if you prefer using a specific version/branch:

npm install -g PublikPrinciple/obsidian-mcp-rest#main

Configuration

1. First, configure Obsidian Local REST API plugin:

   • Install the Local REST API plugin in Obsidian
   • Configure the API port (default: 27123)
   • Generate and save an API key

2. Create a configuration file config.json:

{
  "obsidian": {
    "apiKey": "your-api-key-here",
    "port": 27123,
    "host": "localhost"
  },
  "server": {
    "name": "obsidian-mcp",
    "version": "1.0.0"
  }
}

Usage

1. Start the server:

   obsidian-mcp-rest --config path/to/config.json

2. The server will start and listen for MCP requests via stdin/stdout.

Using with Claude Desktop

1. Configure Claude Desktop to use this MCP server:

   • Open Claude Desktop settings
   • Navigate to the MCP section
   • Add new server configuration:

     {
       "name": "obsidian-mcp",
       "command": "obsidian-mcp-rest",
       "args": ["--config", "path/to/config.json"]
     }

2. Claude can now access your Obsidian vault through commands like:

   Read note "Projects/MyProject.md"
   List all notes in "Projects" folder
   
   Search for notes containing "typescript"

Available Tools

• listNotes: List all notes in the vault or a specific folder
• readNote: Read the contents of a specific note
• writeNote: Create or update a note
• searchNotes: Search for notes using a query string
• getMetadata: Get metadata for a specific note

Security

• The server only runs locally and communicates through stdin/stdout
• All requests to Obsidian REST API are authenticated with your API key
• No external network access is required
• Data remains local to your machine
