WHAT IT DOES

What list_project_variables does on Gitlab Mcp

AI agents call list_project_variables to retrieve information from Gitlab Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_project_variables is rated Low

This tool retrieves CI/CD variables from a GitLab project. While it performs a Read operation (no data is modified), CI/CD variables often contain sensitive secrets, API keys, and credentials. Unauthorized disclosure of these variables poses a medium severity risk due to potential credential compromise and lateral attack surface expansion.

From the tool's definition Tool name is 'list_project_variables' and description states it 'List CI/CD variables for a project' — a query/retrieval operation with no modifications or side effects.

RECOMMENDED RULE

The rule that runs list_project_variables safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Gitlab Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_project_variables, this is the rule to start with:

list_project_variables Allowed

list_project_variables is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Gitlab Mcp, apply this rule, and every list_project_variables call is checked against it from then on.
