start_database · Coolify MCP Server MCP: Risk & Policy

WHAT IT DOES

What start_database does on Coolify MCP Server

AI agents invoke start_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 start_database needs a policy

Starting a database is an operational trigger that changes system state and affects running services. While reversible (a database can be stopped), it is an Execute-category action because it runs an external operation whose consequences depend on the argument passed.

From the tool's definition Tool performs 'Start a database' — an operational action that triggers external infrastructure state change on the Coolify PaaS platform.

start_database Rate-limited

start_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.
