Uninstall an app from a device. Destructive: removes the app and its data.
AI agents call uninstall_app to permanently remove resources in React Native Dev — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Uninstalling an app is an irreversible operation that cannot be undone without reinstalling. It permanently removes the application and all its stored data from the device.
From the tool's definition Tool description explicitly states 'Destructive: removes the app and its data.' The name 'uninstall_app' and description confirm irreversible deletion of application and associated data.
Attacks that exploit this kind of access
Uninstall an app from a device. Destructive: removes the app and its data. It is categorised as a Destructive tool in the React Native Dev MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the React Native Dev MCP server in PolicyLayer and add a rule for uninstall_app: 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 React Native Dev. Nothing to install.
uninstall_app 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_app 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_app. 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_app is provided by the React Native Dev MCP server (luizhbesper/react-native-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
