WHAT IT DOES

What snapshot_restore does on Uefn

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

RISK

Why snapshot_restore is rated Critical

Restoring a snapshot overwrites the current level state entirely, irreversibly discarding any changes made since the snapshot was taken. This is a destructive operation because the current unsaved state cannot be recovered after restoration.

RECOMMENDED RULE

The rule that runs snapshot_restore safely

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

snapshot_restore Hidden

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

The button opens the PolicyLayer dashboard: create your workspace, connect Uefn, apply this rule, and every snapshot_restore call is checked against it from then on.
