MCP.Pizza Chef: GongRzhe

Long automated jobs usually run until they hit something ambiguous, then either stop or guess. This one opens a small window on your desktop instead: a question, a list of choices, a longer text box, or a plain yes-or-no confirmation. It waits for your reply and carries on with it. Windows, macOS, and Linux each get a native-looking dialog, no account or key is needed, and Mac users grant one accessibility permission the first time.
