Clear one buffer: console logs, network requests, network mocks, state changes, or render profile. Use target param. App data reset is clear_state.
AI agents call clear 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.
Clearing buffers (console logs, network requests, mocks, state changes, render profiles) destroys the accumulated diagnostic data irreversibly. While the impact is limited to monitoring/debug data rather than user data, the action cannot be undone once performed, placing it in the Destructive category.
From the tool's definition 'Clear one buffer: console logs, network requests, network mocks, state changes, or render profile' — clearing/resetting buffers is irreversible loss of captured data
Attacks that exploit this kind of access
Clear one buffer: console logs, network requests, network mocks, state changes, or render profile. Use target param. App data reset is clear_state. 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: 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 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 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. 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 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.
