WHAT IT DOES

What promote_milestone does on Gitlab Mcp

AI agents use promote_milestone to create or update resources in Gitlab Mcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Gitlab Mcp environment.

RISK

Why promote_milestone is rated Medium

This tool modifies milestone metadata (status/stage) rather than deleting it, making it a Write action. It is reversible (can be demoted back) and affects only milestone lifecycle state within the project. Severity is medium because incorrect promotion could disrupt project planning workflows, but the change is non-destructive and localized to milestone management, not core project data or financial systems.

From the tool's definition Tool performs 'promote_milestone' which modifies milestone state to 'next stage' — a state change operation that updates data within GitLab.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

promote_milestone Rate-limited

promote_milestone stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

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