WHAT IT DOES

What unifi_restart_device does on UniFi Network MCP Server

AI agents invoke unifi_restart_device to trigger actions in UniFi Network 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 unifi_restart_device needs a policy

This tool triggers a real-world action (device reboot) that disrupts network operations and causes temporary unavailability. While not permanently destructive or financial, it executes an external operation with significant blast radius—rebooting critical network infrastructure could impact business continuity.

From the tool's definition Tool description states 'Restart (reboot) a device' and explicitly notes the device 'will be unreachable for ~1–3 minutes,' indicating execution of a disruptive external operation whose effects depend on which device is targeted.
