THE RISK

Low Risk

Why code-review needs a policy

Code review is a read/analysis operation: it inspects existing code and returns feedback or suggestions. It does not write, execute, or delete anything. The blast radius is low since misuse at most produces incorrect or misleading suggestions, but causes no direct side effects on systems or data.

From the tool's definition 'Perform automated code review and provide suggestions' — the tool reads/analyzes code and produces suggestions without modifying anything.

POLICY

How to control code-review

PolicyLayer is an MCP gateway — it sits between your AI agents and VibeCoding System, and nothing reaches the server without passing your rules. This is the rule we recommend for code-review:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "code-review": {}
  }
}

code-review 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 VibeCoding System — 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 code-review

What does the code-review tool do? +

Perform automated code review and provide suggestions. It is categorised as a Read tool in the VibeCoding System MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on code-review? +

Register the VibeCoding System MCP server in PolicyLayer and add a rule for code-review: 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 VibeCoding System. Nothing to install.

What risk level is code-review? +

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

Can I rate-limit code-review? +

Yes. Add a rate_limit block to the code-review 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 code-review completely? +

Set action: deny in the PolicyLayer policy for code-review. 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 code-review? +

code-review is provided by the VibeCoding System MCP server (zenobia000/vibecoding-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every VibeCoding System tool call.

Start from VibeCoding System, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
