shizuku_show · Android MCP Server MCP: Risk & Policy

WHAT IT DOES

What shizuku_show does on Android MCP Server

AI agents invoke shizuku_show 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_show needs a policy

The tool starts/launches the Shizuku app, which is a privileged Android service that grants elevated API access to other apps. Launching it constitutes an external operation on the device. Shizuku itself enables high-privilege operations, so starting it could be a precursor to privileged actions, but the tool itself is classified as Execute (triggering an app launch).

From the tool's definition 显示/启动 Shizuku App 窗口 — launches/starts the Shizuku application window, triggering an external operation on the Android device
