# Delete a stack (ungroup its frames)

> Dissolves the stack: the grouping is removed and every member frame returns to loose, individual display. The photos themselves are untouched — nothing is trashed or deleted from the library; like `remove_assets_from_album`, this only removes an organizational grouping. Use `trash_assets` to soft-delete the underlying assets.

        Carries no fields — the HTTP 200 + empty JSON object is itself the
        success

        signal. Exists so MCP tools generated from these endpoints have a real

        ``outputSchema`` (rather than the null schema FastMCP emits for 204

        responses), which ChatGPT's MCP submission tooling requires.
