autogui_stop_task · MCPHub MCP: Risk & Policy

WHAT IT DOES

What autogui_stop_task does on MCPHub

AI agents invoke autogui_stop_task to trigger actions in MCPHub. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why autogui_stop_task needs a policy

This tool stops an active GUI automation task, which is an execute operation that controls external automation workflows. While not immediately destructive, stopping a running task can interrupt critical processes and cause data loss or inconsistent state if the task was mid-operation. Confidence is high because the Chinese description clearly indicates active task termination.

From the tool's definition '停止当前正在运行的GUI自动化任务' (Stop the currently running GUI automation task). The tool terminates an external automation process, which is an Execute action that triggers effects on system state.
