Delete a comment
AI agents call youtrack_delete_comment to permanently remove resources in YouTrack MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of comments is a destructive operation that cannot be undone. Once deleted, the comment content is permanently removed from the issue tracking system. This poses a high risk if an AI agent misuses it to remove important discussion history, audit trails, or collaborative feedback. High severity due to permanent data loss and potential loss of critical context for issue resolution.
From the tool's definition Tool name is 'youtrack_delete_comment' with description 'Delete a comment' — the verb 'delete' and explicit description indicate irreversible removal of data.
