## Why unifi_create_voucher is rated Medium

The tool creates new data (vouchers, which are likely temporary or permanent access credentials in the UniFi Access system). This is reversible as vouchers can typically be revoked or deleted. However, severity is elevated to high because misuse could grant unauthorized physical or system access to facilities or resources.

From the tool's own definition: "Tool named 'unifi_create_voucher' that operates within a UniFi Access system for managing doors, credentials, policies, visitors, and events. Creates new vouchers (likely access credentials or temporary tokens)."

## Use case

AI agents use unifi_create_voucher 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.
