WHAT IT DOES

What pool_export does on Truenas

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

RISK

Why pool_export is rated Critical

Exporting/disconnecting a storage pool is explicitly labeled as destructive. It disconnects the pool from the system, making all data on it inaccessible until re-imported. This operation cannot be trivially undone and could cause significant data unavailability or loss if datasets are in use, justifying a high severity rating.

RECOMMENDED RULE

The rule that runs pool_export 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 pool_export, this is the rule to start with:

pool_export Hidden

pool_export 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 Truenas, apply this rule, and every pool_export call is checked against it from then on.
