WHAT IT DOES

What upgrade_kubernetes_cluster does on CloudStack MCP Server

AI agents invoke upgrade_kubernetes_cluster to trigger actions in CloudStack 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
