Implementation Reference
- The handler function for the "get_user" MCP tool. It fetches detailed user information from the Panther REST API endpoint `/users/{user_id}`. Handles 404 not found and other errors, returning structured success/failure responses. Input schema defined via Annotated[str, Field(...)] with description and examples. Decorated with @mcp_tool for automatic registration, including permissions.
