What unifi_authorize_guest does on UniFi Network MCP Server

WHY IT NEEDS A POLICY

Why unifi_authorize_guest needs a policy

This tool grants network access to a guest client via a captive portal. It modifies authorization state (creates/extends a session), which is a reversible write operation. It does not delete data, execute arbitrary code, or move money. The severity is medium because unauthorized guest access grants network entry but is limited to hotspot/guest network scope.

From the tool's definition Authorize a guest client through a captive-portal hotspot. Optional limits override hotspot defaults. Idempotency: not safe to retry — re-authorizing extends the session.
