redeploy_app · Truenas Ws MCP: Risk & Policy

WHAT IT DOES

What redeploy_app does on Truenas Ws

AI agents invoke redeploy_app to trigger actions in Truenas Ws. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why redeploy_app needs a policy

Redeploying an app triggers an external operation that restarts/recreates a running application. This is an Execute-category action as it causes the app to stop and restart, potentially causing downtime. It is not Destructive (no data is deleted), not Write (no data is created/modified persistently), but it triggers an external operational effect whose impact depends on the app being redeployed.

redeploy_app Rate-limited

redeploy_app stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
