stop_database · Coolify MCP Server MCP: Risk & Policy

WHAT IT DOES

What stop_database does on Coolify MCP Server

AI agents invoke stop_database to trigger actions in Coolify MCP Server. 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 stop_database needs a policy

The tool executes a state-changing action on an external service (Coolify-managed database) that is not immediately reversible without manual intervention. While not permanently destructive (the database persists and can be restarted), stopping a production database causes immediate service downtime and application failures.

From the tool's definition Tool name: 'stop_database'; description: 'Stop a database'. This triggers an external operation (stopping a running database service) whose effects are immediate and consequential.

stop_database Rate-limited

stop_database 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.
