THE RISK

Low Risk

Why gitlab_list_cicd_variables needs a policy

This tool queries and retrieves CI/CD variables without side effects. It performs a read-only operation to fetch configuration data. While CI/CD variables may contain sensitive information (secrets, credentials), the tool itself does not expose, modify, or delete them — it only lists them. The risk is low for the action itself, though the data returned may be sensitive.

From the tool's definition Tool name contains 'list' and description states 'List CI/CD variables for a project' — a retrieval operation with no modification, deletion, or execution.

POLICY

How to control gitlab_list_cicd_variables

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

policy.json

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

gitlab_list_cicd_variables 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 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.
