restart_application · Coolify MCP Tools MCP: Risk & Policy

WHAT IT DOES

What restart_application does on Coolify MCP Tools

AI agents invoke restart_application to trigger actions in Coolify MCP Tools. 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 restart_application needs a policy

The restart_application tool executes an action on infrastructure that causes observable side effects—stopping and restarting an application. While not destructive (data is not permanently lost) or financial, this is clearly an Execute operation because it triggers external operations whose effects depend on the specified application.

From the tool's definition Tool name is 'restart_application' with description 'Restart an application'. This performs an operational action that triggers external effects (stopping and restarting a running service/application in Coolify infrastructure).

restart_application Rate-limited

restart_application 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.
