THE RISK

Low Risk

Why analyze_codebase_performance needs a policy

This is a static analysis tool that scans code to identify performance bottlenecks and issues. It does not execute arbitrary code, modify the codebase, delete files, or trigger external operations based on input. The operation is read-only with no side effects, making it a Read category tool with low severity risk.

From the tool's definition The tool name and description indicate it 'Analyze[s] entire React Native codebase for performance issues' - a query/analysis operation with no modification, deletion, or execution of code. It retrieves and examines data about performance characteristics.

POLICY

How to control analyze_codebase_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 analyze_codebase_performance:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "analyze_codebase_performance": {}
  }
}

analyze_codebase_performance is read-only, so it stays allowed — but 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 analyze_codebase_performance

What does the analyze_codebase_performance tool do? +

Analyze entire React Native codebase for performance issues. It is categorised as a Read tool in the React Native MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on analyze_codebase_performance? +

Register the React Native MCP Server MCP server in PolicyLayer and add a rule for analyze_codebase_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 analyze_codebase_performance? +

analyze_codebase_performance is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit analyze_codebase_performance? +

Yes. Add a rate_limit block to the analyze_codebase_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 analyze_codebase_performance completely? +

Set action: deny in the PolicyLayer policy for analyze_codebase_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 analyze_codebase_performance? +

analyze_codebase_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.
