WHAT IT DOES

What unifi_create_usergroup does on UniFi Access MCP

AI agents use unifi_create_usergroup to create or update resources in UniFi Access MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your UniFi Access MCP environment.

RISK

Why unifi_create_usergroup is rated Medium

The tool creates a new user group within a UniFi Access control system, which is a reversible write operation. This is Write rather than Execute because it modifies configuration state rather than triggering external actions. Severity is medium because misconfigured user groups could grant unintended access privileges, but the impact is limited to credential/policy scope and is reversible.

From the tool's definition Tool name 'unifi_create_usergroup' contains 'create', indicating data creation. Server description mentions 'Manage UniFi Access doors, credentials, policies, visitors, and events', confirming this tool creates access control data.
