Bridges Obsidian vaults through the Local REST API, enabling intelligent note management, knowledge discovery, and conversational access to personal knowledge bases with semantic search, daily note handling, and task-oriented operations designed for knowledge workers.
  1. Ensure Obsidian Local REST API is Running

    • Install and start Obsidian Local REST API according to its documentation.
    • By default, it should be accessible at http://obsidian-local-rest-api.test.
    • If you are not using Laravel Valet, it may be at http://localhost:8000 or another local URL you configure.
  2. Determine API Authentication Requirement

    • Check if your Obsidian Local REST API instance requires authentication (an API key/token), based on how you installed/configured it.
    • If authentication is required, obtain the API key from your Obsidian Local REST API plugin settings. If it does not mention a key, you can leave the OBSIDIAN_API_KEY value empty.
  3. Copy the API URL and (Optional) API Key

    • API URL example: http://obsidian-local-rest-api.test or http://localhost:8000
    • API Key: Copy the value provided by the plugin, if set. (Find this in Obsidian settings under the Local REST API plugin.)
  4. Fill in the FastMCP Connection Interface

    • Click the Install Now button in your FastMCP interface.
    • When prompted, set the following environment variables:
      • OBSIDIAN_API_URL: Paste your API URL (e.g., http://obsidian-local-rest-api.test)
      • OBSIDIAN_API_KEY: Paste your API key if required, or leave blank if not needed.
  5. Save and Activate

    • Confirm your entries and save the settings in the FastMCP connection interface.
    • The MCP server will now connect to your Obsidian REST API using these credentials.

Note: If you encounter connection errors or "Unauthorized" messages, double-check the API URL and, if needed, ensure the API key is correct and copied without extra spaces or line breaks.
