## Why access_create_visitor is rated Medium

Creating visitor records is a reversible write operation that modifies access control data. This is severe because visitor creation can grant physical access to facilities and potentially create security audit issues, but it is not destructive (can be undone via delete_visitor), not financial, and not execute-level code running.

From the tool's own definition: "Tool name is 'access_create_visitor' which indicates creation of visitor records in a UniFi Access control system."

## Use case

AI agents use access_create_visitor 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.
