Uninstall application from device
AI agents call uninstall_application to permanently remove resources in MCP Emulator Controller — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Uninstalling an application permanently removes it from the device and cannot be reversed by the tool itself. This meets the Destructive category definition: 'irreversibly deletes or overwrites data, or actions that cannot be undone.' While not as critical as wiping entire device data, unauthorized uninstallation of critical system or user applications could disrupt device functionality.
From the tool's definition Tool name 'uninstall_application' and description 'Uninstall application from device' directly indicate removal of installed applications. Uninstallation is an irreversible action that cannot be undone without re-installation.
Attacks that exploit this kind of access
Uninstall application from device. It is categorised as a Destructive tool in the MCP Emulator Controller MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the MCP Emulator Controller MCP server in PolicyLayer and add a rule for uninstall_application: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MCP Emulator Controller. Nothing to install.
uninstall_application is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the uninstall_application rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for uninstall_application. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
uninstall_application is provided by the MCP Emulator Controller MCP server (teemo4621/mcp-emulator-controller). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
