shizuku_hide · Android MCP Server MCP: Risk & Policy

WHAT IT DOES

What shizuku_hide does on Android MCP Server

AI agents invoke shizuku_hide to trigger actions in Android MCP Server. 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 shizuku_hide needs a policy

The tool hides the Shizuku floating window by shrinking it and force-stopping the Shizuku App UI. Force-stopping an app process is an external system operation (Execute category). While it doesn't permanently delete data, it forcibly terminates a running process, which could disrupt ongoing operations. The severity is medium because it affects a specific system service (Shizuku) but is generally recoverable.

From the tool's definition force-stop App UI — triggers a force-stop of an application's UI process, which is an external system operation affecting running processes
