force_stop_app · Android MCP Server MCP: Risk & Policy

WHAT IT DOES

What force_stop_app does on Android MCP Server

AI agents invoke force_stop_app 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 force_stop_app needs a policy

Force stopping an app terminates running processes immediately. This is an Execute action that triggers an external operation (process termination) on the Android device. While it is somewhat reversible (the app can be restarted), it forcefully kills processes which can cause data loss or interrupt active operations. The blast radius is high because misuse could kill critical system or user applications.
