WHAT IT DOES

What create_group_milestone does on Gitlab Mcp

AI agents use create_group_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 create_group_milestone is rated Medium

This tool creates a new milestone object in GitLab, which is reversible (milestones can be edited or deleted). It modifies project/group data by adding a new milestone, but does not execute code, delete data irreversibly, or move money. The blast radius is medium because creating milestones affects project tracking and timeline planning, but malicious creation of spurious milestones can be remediated.

From the tool's definition Tool name 'create_group_milestone' and description 'Create a new group milestone' indicate creation of a new entity within GitLab's project management system.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

create_group_milestone Rate-limited

create_group_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.
