WHAT IT DOES

What delete_group_variable does on Gitlab Mcp

AI agents call delete_group_variable to permanently remove resources in Gitlab Mcp, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete_group_variable is rated Critical

This tool permanently removes a CI/CD variable, which cannot be undone. CI/CD variables are often critical for build pipelines, deployments, and infrastructure automation—deleting them could break workflows or disable security controls. While not data destruction in the traditional sense, it is an irreversible configuration change with potential blast radius across multiple pipelines and projects in a group.

From the tool's definition Tool name is 'delete_group_variable' and description states 'Delete a CI/CD variable from a group'. The verb 'Delete' combined with the action of removing a CI/CD variable indicates irreversible removal of configuration data.

RECOMMENDED RULE

The rule that runs delete_group_variable 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 delete_group_variable, this is the rule to start with:

delete_group_variable Hidden

delete_group_variable is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
