WHAT IT DOES

What unifi_upgrade_device does on UniFi Access MCP

AI agents invoke unifi_upgrade_device to trigger actions in UniFi Access MCP. 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.

RISK

Why unifi_upgrade_device is rated High

Triggering a firmware upgrade is an external operation that modifies device firmware and causes a reboot/downtime. It is not a simple write (it runs an upgrade process on physical hardware), not destructive in the irreversible-deletion sense, but it executes a significant operational action with potentially wide blast radius if applied to the wrong device or with bad firmware.

RECOMMENDED RULE

The rule that runs unifi_upgrade_device safely

PolicyLayer is an MCP gateway: it sits between your AI agents and UniFi Access MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For unifi_upgrade_device, this is the rule to start with:

unifi_upgrade_device Rate-limited

unifi_upgrade_device 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.
