Implementation Reference

• src/f1_mcp_server/f1_data.py:186-249 (handler)

  Core handler function that implements the get_session_results tool logic using FastF1 API to load session data, extract results, serialize to JSON-compatible format, and handle validation/errors.

  def get_session_results(
      year: Any, event_identifier: str, session_name: str
  ) -> dict[str, Any]:

      Get results for a specific Formula One session.

          session_name (str): Session type (Race, Qualifying, Sprint, etc.)
