Implementation Reference

• src/airflow/pool.py:52-65 (handler)

  The async handler function that implements the core logic of the 'get_pool' tool. It takes a pool_name parameter, calls the Airflow PoolApi to retrieve the pool, and returns the details as TextContent.

  async def get_pool(
      pool_name: str,
  ) -> List[Union[types.TextContent, types.ImageContent, types.EmbeddedResource]]:
      """
      Get a pool by name.
  
      Args:
          pool_name: The pool name.
  
      Returns:
          The pool details.
      """
      response = pool_api.get_pool(pool_name=pool_name)
      return [types.TextContent(type="text", text=str(response.to_dict()))]

• src/airflow/pool.py:16-16 (registration)

  The registration tuple for the 'get_pool' tool within the get_all_functions list, specifying the handler function, tool name, description, and read-only status.

  (get_pool, "get_pool", "Get a pool by name", True),

• src/airflow/pool.py:12-20 (helper)

  Helper function get_all_functions that returns the list of tool tuples for the pool API, including the 'get_pool' tool, which is used for registration.

  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),
      ]

• src/main.py:90-91 (registration)

  The registration loop in main.py that calls app.add_tool for each tool from get_pool_functions (among others), effectively registering the 'get_pool' tool.

  for func, name, description, *_ in functions:
      app.add_tool(func, name=name, description=description)

• src/main.py:33-33 (helper)

  Mapping in APITYPE_TO_FUNCTIONS that associates APIType.POOL with get_pool_functions (aliased get_all_functions from pool.py), enabling its use in registration.

  APIType.POOL: get_pool_functions,
