Group must be empty.
AI agents call deletedevicegroup 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.
Deleting a device group is an irreversible destructive action. While the group must be empty first (limiting some blast radius), removing organizational groupings in digital signage infrastructure can disrupt device management, scheduling, and content delivery. Consistent with sibling tools like deletedevice, deletemedia, deleteplaylist, etc., this is a Destructive operation.
From the tool's definition Tool name 'deletedevicegroup' clearly indicates deletion of a device group; description states 'Group must be empty' confirming this is a deletion operation
