    ActiveRecord class name for full detail via ModelDetails::SingleModelFormatter; omit to list all ActiveRecord models with +detail+.

  • detail (String) (defaults to: 'standard') —

    +summary+, +standard+, or +full+ when listing (ignored when +model+ is set)

  • _server_context (Object, nil) (defaults to: nil) —

    reserved for MCP transport metadata (unused)

Returns:

  • (MCP::Tool::Response) —

    Markdown body or an error string wrapped for the MCP client
