Implementation Reference

• mlb_api.py:314-352 (handler)

  The core handler function for the 'get_mlb_team_info' tool. It is decorated with @mcp.tool(), which registers the tool and infers the schema from the type hints and docstring. The function resolves the team name/ID using a helper, fetches team information from the MLB stats API, and returns the data or an error.

  get_team_id_from_name helper function: Maps a team string (name, partial name, or ID) to the numeric team ID by checking a local CSV file, used directly in the handler to resolve the 'team' parameter.
