What unifi_power_cycle_port does on UniFi Access MCP
AI agents invoke unifi_power_cycle_port 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.
Why unifi_power_cycle_port is rated High
Power cycling a PoE port triggers an external hardware operation that disrupts power to connected devices (e.g., access control readers, cameras, door controllers). This is an Execute-category action with high severity because misuse could disable physical security devices like door locks or access readers, potentially compromising physical security infrastructure.

The rule that runs unifi_power_cycle_port 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_power_cycle_port, this is the rule to start with:
unifi_power_cycle_port 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.
The button opens the PolicyLayer dashboard: create your workspace, connect UniFi Access MCP, apply this rule, and every unifi_power_cycle_port call is checked against it from then on.
Questions about unifi_power_cycle_port
Power cycle PoE on a specific switch port. This briefly cuts power to the. It is categorised as a Execute tool in the UniFi Access MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the UniFi Access MCP server in PolicyLayer and add a rule for unifi_power_cycle_port: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches UniFi Access MCP. Nothing to install.
unifi_power_cycle_port is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the unifi_power_cycle_port rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for unifi_power_cycle_port. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
unifi_power_cycle_port is provided by the UniFi Access MCP server (pypi:unifi-protect-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
