## Example call (MCP tools/call, JSON-RPC 2.0)

  "jsonrpc": "2.0",

## Why edit_group_milestone is rated Medium

This tool modifies an existing milestone in a GitLab group, which is a reversible write operation. It does not delete data (Destructive), execute arbitrary commands (Execute), or move money (Financial). The severity is medium because milestone modifications could affect project planning and team coordination, but the blast radius is limited to metadata changes within a single group's milestones.

From the tool's own definition: "Tool name includes 'edit' and description states 'Edit an existing group milestone', indicating modification of existing data."

## Use case

AI agents use edit_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.

## Recommended policy (PolicyLayer)
