Implementation Reference
- src/airflow/dag.py:91-100 (handler)The main handler function implementing the get_dag_details tool. It fetches simplified DAG details from the Airflow API based on dag_id and optional fields, returning the result as text content.
async def get_dag_details( dag_id: str, fields: Optional[List[str]] = None ) -> List[Union[types.TextContent, types.ImageContent, types.EmbeddedResource]]: # Build parameters dictionary kwargs: Dict[str, Any] = {} if fields is not None: kwargs["fields"] = fields response = dag_api.get_dag_details(dag_id=dag_id, **kwargs) return [types.TextContent(type="text", text=str(response.to_dict()))] - src/airflow/dag.py:15-33 (registration)The get_all_functions() in dag.py provides the registration tuple for the get_dag_details tool (function reference, name, description, read-only flag), which is imported and used in src/main.py to register all tools with the MCP server.
