Implementation Reference

• src/airflow/pool.py:84-114 (handler)

  The asynchronous handler function for the 'post_pool' tool. It constructs a Pool object from input parameters and uses the Airflow PoolApi to create the pool, returning the response as text content.

  async def post_pool(
      name: str,
      slots: int,
      description: Optional[str] = None,
      include_deferred: Optional[bool] = None,
  ) -> List[Union[types.TextContent, types.ImageContent, types.EmbeddedResource]]:
      """
      Create a pool.
  
      Args:
          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 created pool details.
      """
      pool = Pool(
          name=name,
          slots=slots,
      )
  
      if description is not None:
          pool.description = description
  
      if include_deferred is not None:
          pool.include_deferred = include_deferred
  
      response = pool_api.post_pool(pool=pool)
      return [types.TextContent(type="text", text=str(response.to_dict()))]

• src/airflow/pool.py:12-20 (registration)

  The get_all_functions() lists all pool-related tools for registration, including the 'post_pool' tool with its handler, name, description, and mutability flag.

  def get_all_functions() -> list[tuple[Callable, str, str, bool]]:
      """Return list of (function, name, description, is_read_only) tuples for registration."""
      return [
          (get_pools, "get_pools", "List pools", True),
          (get_pool, "get_pool", "Get a pool by name", True),
          (delete_pool, "delete_pool", "Delete a pool", False),
          (post_pool, "post_pool", "Create a pool", False),
          (patch_pool, "patch_pool", "Update a pool", False),
