Why gitlab_search_code needs a policy

This tool retrieves/queries code content across projects without creating, modifying, deleting, or executing anything. It is purely informational. Even though it may access code across multiple projects (broad scope), the action itself is read-only with minimal blast radius if misused—the worst outcome is unauthorized information disclosure of code already stored in the GitLab instance.

From the tool's definition Tool name contains 'search' and description states 'Search code across all projects'. The verb 'search' indicates data retrieval with no modification or side effects. No mutations, deletions, or execution of retrieved code mentioned.

POLICY

How to control gitlab_search_code

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

policy.json

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

gitlab_search_code 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 Gitlab — 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 gitlab_search_code

What does the gitlab_search_code tool do? +

Search code across all projects on the GitLab instance. Requires GitLab code search support. It is categorised as a Read tool in the Gitlab MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on gitlab_search_code? +

Register the Gitlab MCP server in PolicyLayer and add a rule for gitlab_search_code: 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 Gitlab. Nothing to install.

What risk level is gitlab_search_code? +

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

Can I rate-limit gitlab_search_code? +

Yes. Add a rate_limit block to the gitlab_search_code 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 gitlab_search_code completely? +

Set action: deny in the PolicyLayer policy for gitlab_search_code. 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 gitlab_search_code? +

gitlab_search_code is provided by the Gitlab MCP server (mcpland/gitlab-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Gitlab tool call.

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