Group must be empty.
AI agents call deletetemplategroup to permanently remove resources in Revel Digital MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool name starts with 'delete' indicating irreversible removal of a template group from the digital signage system. While the group must be empty first (limiting some blast radius), the deletion itself is permanent and cannot be undone. Sibling tools follow the same delete pattern for devices, media, playlists, schedules, etc., confirming this is a destructive operation.
From the tool's definition Tool name 'deletetemplategroup' clearly indicates deletion; description states 'Group must be empty' confirming this is an irreversible delete operation on a template group.
