Revoke guest authorization; the client returns to the captive portal on next request. Idempotent.
AI agents call unifi_unauthorize_guest to permanently remove resources in UniFi Network MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Revoking guest authorization immediately cuts off network access for the client. This is an irreversible action in the moment (the authorization is removed and the client is disconnected from the network), and cannot be undone without explicitly re-authorizing the guest. The blast radius is high as it can disrupt legitimate guest access across a site.

Attacks that exploit this kind of access
Revoke guest authorization; the client returns to the captive portal on next request. Idempotent. It is categorised as a Destructive tool in the UniFi Network MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the UniFi Network MCP Server MCP server in PolicyLayer and add a rule for unifi_unauthorize_guest: 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 Network MCP Server. Nothing to install.
unifi_unauthorize_guest is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the unifi_unauthorize_guest 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_unauthorize_guest. 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_unauthorize_guest is provided by the UniFi Network MCP Server MCP server (owine/unifi-network-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
