THE RISK

Low Risk

Why gitlab_search_project_code needs a policy

This tool performs a search/query operation on project code, which is a read-only action with no side effects. It retrieves information but does not create, modify, delete, or execute code. The low severity reflects that code search poses minimal risk even if misused by an AI agent—it only exposes existing code visibility within the already-accessible project scope.

From the tool's definition Tool name is 'gitlab_search_project_code' and description states 'Search code in a specific project.' The verb 'search' indicates a query operation that retrieves data without modifying or executing anything.

POLICY

How to control gitlab_search_project_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_project_code:

policy.json

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

gitlab_search_project_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.

Questions about gitlab_search_project_code

What does the gitlab_search_project_code tool do? +

Search code in a specific project. 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_project_code? +

Register the Gitlab MCP server in PolicyLayer and add a rule for gitlab_search_project_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_project_code? +

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

Can I rate-limit gitlab_search_project_code? +

Yes. Add a rate_limit block to the gitlab_search_project_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_project_code completely? +

Set action: deny in the PolicyLayer policy for gitlab_search_project_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_project_code? +

gitlab_search_project_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.
