RECOMMENDED RULE

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

pool_status Allowed

pool_status is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

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