WHAT IT DOES

What power_off_vultr_instance does on Cloud Manage MCP Server

AI agents invoke power_off_vultr_instance to trigger actions in Cloud Manage 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 power_off_vultr_instance needs a policy

Powering off a cloud instance is an Execute-level action: it triggers an external operation (force shutdown) on a running server that can cause service disruption, data loss in memory, and application downtime. While it is technically reversible (the instance can be powered back on), the forced shutdown itself can corrupt in-flight data and cause outages.
