Implementation Reference
- src/airflow/dag.py:270-274 (handler)The main handler function for the 'reparse_dag_file' tool. It takes a file_token parameter, calls the Airflow DAG API's reparse_dag_file method, and returns the response as formatted text content.
async def reparse_dag_file( file_token: str, ) -> List[Union[types.TextContent, types.ImageContent, types.EmbeddedResource]]: response = dag_api.reparse_dag_file(file_token=file_token) return [types.TextContent(type="text", text=str(response.to_dict()))] - src/airflow/dag.py:15-33 (registration)The registration function get_all_functions() that lists all DAG-related tools, including reparse_dag_file with its name, description, and read-only status (False). This is used to register the tool with the MCP server.
