WHAT IT DOES

What batch_restart_instances does on MCSManager MCP Server

AI agents invoke batch_restart_instances to trigger actions in MCSManager 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 batch_restart_instances needs a policy

batch_restart_instances triggers real processes with real consequences. An agent gone sideways doesn't fire it once — it starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.
