Implementation Reference

• src/f1_mcp_server/f1_data.py:443-520 (handler)

  The core handler function that implements the get_telemetry tool logic: loads F1 session data, selects driver laps, retrieves telemetry for a specific or fastest lap, processes it into JSON-serializable format, and returns structured data with error handling.

  def get_telemetry(
      year, event_identifier, session_name, driver_identifier, lap_number=None
  ):
      """
      Get telemetry data for a specific lap or fastest lap.
  
      Args:
          year (int or str): The year of the F1 season
          event_identifier (str): Event name or round number
          session_name (str): Session type (Race, Qualifying, Sprint, etc.)
          driver_identifier (str): Driver number, code, or name
          lap_number (int, optional): Specific lap number or None for fastest lap
