WHAT IT DOES

What cloudsync_restore does on Truenas

AI agents use cloudsync_restore to create or update resources in Truenas, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Truenas environment.

RISK

Why cloudsync_restore is rated Medium

This tool creates or modifies data on the local system by pulling data from cloud storage. While restoration is technically reversible (the original local data may be overwritten but the cloud source persists), the operation itself is a Write action that alters the local filesystem. It is not Destructive because the operation doesn't irreversibly delete data—it restores it.

From the tool's definition Tool name 'cloudsync_restore' and description 'Restore data from cloud to a local path' indicate the tool modifies local storage by writing/importing data from remote sources.

RECOMMENDED RULE

The rule that runs cloudsync_restore safely

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

cloudsync_restore Rate-limited

cloudsync_restore stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
