update_issue · Qodev Gitlab MCP: Risk & Policy

WHAT IT DOES

What update_issue does on Qodev Gitlab

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

WHY IT NEEDS A POLICY

Why update_issue needs a policy

Update operations modify data (issue content, status, labels, assignees) but do not irreversibly delete or destroy it. This places it in Write category. Severity is medium because issue updates could change project state, workflow, or visibility, but the effect is scoped to a single issue and reversible.

From the tool's definition Tool name is 'update_issue' on a GitLab integration server; sibling tools like 'create_issue', 'create_merge_request', 'create_release' confirm this server performs write operations. The tool modifies issue state/properties reversibly.
