WHAT IT DOES

What set_epic_milestone does on Mcp Gitlab

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

WHY IT NEEDS A POLICY

Why set_epic_milestone needs a policy

This tool modifies epic state by associating a milestone, but the operation is reversible and non-destructive. It does not delete, execute arbitrary code, move money, or trigger external operations—it simply updates an epic property. This makes it a Write category risk.

From the tool's definition set_epic_milestone updates an epic's milestone association (Work Items API), which modifies epic metadata reversibly.
