AI agents call uninstall-app to permanently remove resources in MCP Appium Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Uninstalling an app is a destructive operation that permanently removes the application and its associated data from the device. This is irreversible without explicit user action to reinstall. While not as severe as deleting arbitrary files, the scope is focused and specific to app removal.
From the tool's definition Tool name 'uninstall-app' and description 'Uninstall an Android application' indicate irreversible removal of application data and installation, which cannot be undone without reinstalling.
Documented attack patterns abuse exactly the kind of access uninstall-app gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Appium Server, and nothing reaches the server without passing your rules. This is the rule we recommend for uninstall-app:
{
"version": "1",
"default": "deny",
"hide": [
"uninstall-app"
]
}uninstall-app disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
