stop_application · Coolify MCP Tools MCP: Risk & Policy

WHAT IT DOES

What stop_application does on Coolify MCP Tools

AI agents invoke stop_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.
