Obsidian MCP Server

An advanced MCP (Model Context Protocol) server that turns your Obsidian vault into a dynamic brain for your AI (Claude Desktop, Cursor, Claude Code, Cline, etc.). Much more than a file reader: it is an ecosystem of tools for knowledge management, workflow automation, and semantic analysis.

Features

Tool Ecosystem (30+)

The server exposes a wide variety of tools categorized by function:

• Navigation: Intelligent listing, recursive reading, and advanced searching.
• Creation and Editing: Automatic template usage, location suggestions, and non-destructive editing preserving metadata (frontmatter/YAML).
• Analysis and Quality: Vault statistics, tag synchronization with the official registry, and integrity checks.
• Graphs and Connections: Backlink analysis, orphan note detection, and local graph visualization.
• Skills (Agents): Dynamic loading of AI personalities/roles from your vault ({vault}/.agents/skills/).
• Semantic Search (RAG): Meaning-based searches, suggestions for non-obvious connections, and vector indexing.
• YouTube: Extraction of transcripts to feed your knowledge base.

Built-in Intelligence

• Vault-Agnostic Architecture: Independent of your folder structure; it uses intelligent auto-detection to find templates and resources.
• Security: Strict protection of sensitive folders via .forbidden_paths and vault privacy configurations.
• Customizable Skills: Define specific AI roles directly within your vault (.agents/skills/) for specialized tasks.

Quick Setup

Prerequisites

• Python 3.11+
• uv (Recommended)

Steps

1. Clone:

   git clone https://github.com/Vasallo94/obsidian-mcp-server.git
   cd obsidian-mcp-server
   

2. Install:

   make install
   # For semantic search capabilities (RAG):
   pip install "obsidian-mcp-server[rag]"
   

3. Configure:

   cp .env.example .env
   # Edit .env with the absolute path to your Obsidian vault

Usage

The MCP server connects to compatible clients using the uv run obsidian-mcp-server command. Below are setup instructions for popular AI clients.

Claude Desktop Integration

Add the following to your claude_desktop_config.json:

{
  "mcpServers": {
    "obsidian": {
      "command": "uv",
      "args": ["run", "obsidian-mcp-server"],
      "env": {
        "OBSIDIAN_VAULT_PATH": "/Absolute/Path/To/Your/Vault"
      }
    }
  }
}

Cursor & Cline Integration

For other clients like Cursor or Cline, you can add it as a new MCP server in their settings panel by specifying:

• Type: command
• Command: uv run obsidian-mcp-server
• Ensure the OBSIDIAN_VAULT_PATH environment variable is available to the instance running the command.
