Clear app data (Android) or reset permissions (iOS). iOS full reset needs uninstall+reinstall.
AI agents call clear_state to permanently remove resources in React Native — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool destroys application data and state permanently. On Android, clearing app data removes all stored information. On iOS, the full reset requires uninstall and reinstall, both of which are irreversible actions. An AI agent misusing this tool could destroy user data, app configurations, and cached content without recovery options.
From the tool's definition 'Clear app data (Android) or reset permissions (iOS). iOS full reset needs uninstall+reinstall.' — the tool irreversibly deletes application state and data, and on iOS involves uninstall/reinstall, which cannot be undone without external intervention.
Attacks that exploit this kind of access
Clear app data (Android) or reset permissions (iOS). iOS full reset needs uninstall+reinstall. It is categorised as a Destructive tool in the React Native MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the React Native MCP server in PolicyLayer and add a rule for clear_state: 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. Nothing to install.
clear_state 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 clear_state 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 clear_state. 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.
clear_state is provided by the React Native MCP server (@ohah/react-native-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
