Implementation Reference
- src/airflow/dag.py:113-115 (handler)The unpause_dag tool handler: patches the DAG to set is_paused=False via the Airflow DAG API and returns the response.async def unpause_dag(dag_id: str) -> List[Union[types.TextContent, types.ImageContent, types.EmbeddedResource]]: response = dag_api.patch_dag(dag_id=dag_id, dag_update_request={"is_paused": False}) return [types.TextContent(type="text", text=str(response.to_dict()))]
