Implementation Reference
- src/airflow/pool.py:117-147 (handler)The async handler function for the 'patch_pool' MCP tool. It constructs a Pool object with optional updates to slots, description, or include_deferred, then calls the Airflow PoolApi to patch the pool and returns the response as text.
async def patch_pool( pool_name: str, slots: Optional[int] = None, description: Optional[str] = None, include_deferred: Optional[bool] = None, ) -> List[Union[types.TextContent, types.ImageContent, types.EmbeddedResource]]: """ Update a pool. Args: pool_name: The pool name. slots: The number of slots. description: The pool description. include_deferred: Whether to include deferred tasks in slot calculations. Returns: The updated pool details. """ pool = Pool() if slots is not None: pool.slots = slots if description is not None: pool.description = description if include_deferred is not None: pool.include_deferred = include_deferred response = pool_api.patch_pool(pool_name=pool_name, pool=pool) return [types.TextContent(type="text", text=str(response.to_dict()))] - src/airflow/pool.py:12-20 (registration)The get_all_functions() function returns a list of tuples for registering MCP tools, including the patch_pool tool with name 'patch_pool', description 'Update a pool', and is_read_only=False.
