Obsidian MCP

Vault access as structured tools

Connect Claude or Cursor to your Obsidian vault to search, read and edit notes — turning an agent into a research and writing partner over your own knowledge base. Setup goes through the Obsidian Local REST API plugin: enable it, copy the API key, and Obsidian must stay open (the REST API runs inside the app).

Install Obsidian MCP

Paste into claude_desktop_config.json

{
  "mcpServers": {
    "obsidian": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-obsidian"
      ]
    }
  }
}

After adding the server, fully restart your MCP client. Replace <placeholders> (tokens, paths) with your own values.

Known limitations

Requires the Local REST API community plugin and Obsidian to be running. The plugin uses a self-signed HTTPS cert, so some setups need the cert trusted. Keep the API key private.
