WHAT IT DOES

What unprotect_branch does on Gitlab Mcp

AI agents call unprotect_branch 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 unprotect_branch is rated Critical

Removing branch protection is an irreversible security configuration change that exposes the branch to force pushes, deletions, and unreviewed commits. This weakens access controls and cannot be automatically undone, making it destructive in nature with high blast radius if misused by an AI agent.

RECOMMENDED RULE

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

unprotect_branch Hidden

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

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