  notes: >-
    The Trellis REST Data API (V2, introduced May 2024) authenticates with a
    unique API key sent in the Authorization header. The API key is generated
    from the Trellis account Settings page (bottom-left of the app). Keys are
    private, must not be shared publicly, and all requests should be made
    server-side. The separate remote MCP server (mcp.trellis.law) authenticates
    with OAuth 2.0 so that no API key is exposed to the client.
