Implementation Reference
- src/airflow/dagrun.py:215-220 (handler)The async handler function that implements the core logic of the set_dag_run_note tool by creating a SetDagRunNote model and calling the Airflow DAGRunApi to update the DAG run note.
async def set_dag_run_note( dag_id: str, dag_run_id: str, note: str ) -> List[Union[types.TextContent, types.ImageContent, types.EmbeddedResource]]: set_dag_run_note = SetDagRunNote(note=note) response = dag_run_api.set_dag_run_note(dag_id=dag_id, dag_run_id=dag_run_id, set_dag_run_note=set_dag_run_note) return [types.TextContent(type="text", text=str(response.to_dict()))] - src/airflow/dagrun.py:17-29 (registration)The registration point where the set_dag_run_note tool is listed in the get_all_functions() return value for MCP tool registration, specifying the handler function, name, description, and read-only status.
