THE RISK

High Risk

Why optimize_performance needs a policy

While the name suggests read-only analysis, the server's context of 'automated code remediation' and 'code generation' indicates this tool likely executes transformations on the codebase. Even if it only provides suggestions, paired with the sibling tool 'debug_issue' and the remediation capabilities described, it represents a tool that triggers external operations affecting code state.

From the tool's definition Tool performs 'performance optimization suggestions' which implies analyzing and potentially transforming code.

Documented attack patterns abuse exactly the kind of access optimize_performance gives an agent:

POLICY

How to control optimize_performance

PolicyLayer is an MCP gateway — it sits between your AI agents and React Native MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for optimize_performance:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "optimize_performance": {
      "limits": [
        {
          "counter": "optimize_performance_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

optimize_performance stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register React Native MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about optimize_performance

What does the optimize_performance tool do? +

Get performance optimization suggestions for React Native. It is categorised as a Execute tool in the React Native MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on optimize_performance? +

Register the React Native MCP Server MCP server in PolicyLayer and add a rule for optimize_performance: 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 MCP Server. Nothing to install.

What risk level is optimize_performance? +

optimize_performance is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit optimize_performance? +

Yes. Add a rate_limit block to the optimize_performance 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.

How do I block optimize_performance completely? +

Set action: deny in the PolicyLayer policy for optimize_performance. 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.

What MCP server provides optimize_performance? +

optimize_performance is provided by the React Native MCP Server MCP server (mrnitro360/react-native-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every React Native MCP Server tool call.

Start from React Native MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
