WHAT IT DOES

What unifi_delete_backup does on UniFi Access MCP

AI agents call unifi_delete_backup to permanently remove resources in UniFi Access MCP, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why unifi_delete_backup is rated Critical

Deleting a backup file removes it permanently and cannot be undone. This fits the Destructive category. Severity is high because backup deletion could prevent system recovery and cause operational disruption, though it does not directly expose the entire physical access control system (which would be critical). Confidence is high because the intent is explicit and unambiguous.

From the tool's definition Tool name contains 'delete' and description states 'Delete a backup file from the controller' — this is an irreversible destruction of data.

RECOMMENDED RULE

The rule that runs unifi_delete_backup safely

PolicyLayer is an MCP gateway: it sits between your AI agents and UniFi Access MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For unifi_delete_backup, this is the rule to start with:

unifi_delete_backup Hidden

unifi_delete_backup is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
