Implementation Reference
- src/airflow/dag.py:103-105 (handler)The async handler function that executes the get_dag_source tool logic by calling the Airflow DAG API to retrieve the DAG source code and returning it as TextContent.
async def get_dag_source(file_token: str) -> List[Union[types.TextContent, types.ImageContent, types.EmbeddedResource]]: response = dag_api.get_dag_source(file_token=file_token) return [types.TextContent(type="text", text=str(response.to_dict()))] - src/airflow/dag.py:15-33 (registration)Registration of all DAG-related tools, including the tuple for get_dag_source: (get_dag_source, "get_dag_source", "Get a source code", True).
