Implementation Reference
- src/airflow/dagrun.py:200-204 (handler)The main handler function that implements the logic for the 'delete_dag_run' tool by calling the Airflow DAGRunApi to delete the specified DAG run.
async def delete_dag_run( dag_id: str, dag_run_id: str ) -> List[Union[types.TextContent, types.ImageContent, types.EmbeddedResource]]: response = dag_run_api.delete_dag_run(dag_id=dag_id, dag_run_id=dag_run_id) return [types.TextContent(type="text", text=str(response.to_dict()))] - src/airflow/dagrun.py:17-29 (registration)The registration function that includes the 'delete_dag_run' tool in the list of DAG run tools, which is imported and used in src/main.py to register tools with the MCP server.
