Implementation Reference
- libralm_mcp_server.py:158-165 (handler)The handler function decorated with @mcp.tool() that implements the get_book_summary tool. It fetches the book summary by making an authenticated API request to the LibraLM API endpoint /books/{book_id}/summary.
@mcp.tool() def get_book_summary(book_id: str) -> str: """Get the main summary for a book""" try: data = _make_api_request(f"/books/{book_id}/summary") return data.get("summary", "") except Exception as e: raise ValueError(f"Error getting summary for book '{book_id}': {str(e)}") - libralm_mcp_server.py:103-128 (helper)Supporting helper function used by the get_book_summary handler to perform authenticated API requests to the LibraLM service.
