Get memory optimization patterns. Call this when debugging memory leaks or performance issues. Covers useEffect cleanup (listeners, timers), closure memory leaks, React Native DevTools memory profiler, view flattening, R8 shrinking for Android, and a common memory leak sources checklist. Use
AI agents call get-memory-optimization to retrieve information from React Native Expo MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though get-memory-optimization only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Get memory optimization patterns. Call this when debugging memory leaks or performance issues. Covers useEffect cleanup (listeners, timers), closure memory leaks, React Native DevTools memory profiler, view flattening, R8 shrinking for Android, and a common memory leak sources checklist. Use. It is categorised as a Read tool in the React Native Expo MCP MCP Server, which means it retrieves data without modifying state.
Register the React Native Expo MCP server in PolicyLayer and add a rule for get-memory-optimization: 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 Expo MCP. Nothing to install.
get-memory-optimization is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get-memory-optimization 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 get-memory-optimization. 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.
get-memory-optimization is provided by the React Native Expo MCP server (zahargusyatin/react-native-expo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
