Implementation Reference

• src/lightroom_mcp_custom/server.py:858-865 (handler)

  The handler implementation for the 'rotate_left' tool. It includes the @mcp.tool() registration decorator and the logic that calls the underlying 'metadata.rotate_left' bridge function.

  @mcp.tool()
  async def rotate_left(local_ids: list[int] | None = None) -> dict[str, Any]:
      """Rotate selected photos 90 degrees left."""
      ids = validate_local_ids(local_ids)
      payload: dict[str, Any] = {}
      if ids:
          payload["local_ids"] = ids
      return await _call("metadata.rotate_left", payload)
