Uninstalls the specified package from the connected Android device. Requires the package_name parameter, which is the name of the package to uninstall.
AI agents call uninstall_package to permanently remove resources in Ultimate Android MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Uninstalling a package permanently removes the application and its associated data from the device. This is an irreversible action that cannot be undone by the tool itself. While not as severe as wiping an entire device, unauthorized uninstallation of critical system packages or user applications could cause significant device malfunction or data loss.
From the tool's definition Tool description states it 'Uninstalls the specified package from the connected Android device' - uninstall is an irreversible operation that removes application data and cannot be undone without reinstallation.
Documented attack patterns abuse exactly the kind of access uninstall_package gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ultimate Android MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for uninstall_package:
{
"version": "1",
"default": "deny",
"hide": [
"uninstall_package"
]
}uninstall_package disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
