## What it does

The server exposes 106 tools over the Model Context Protocol. It handles domain searches, registrations, transfers, and DNS records. Assistants can also provision Ubuntu virtual servers, attach SSH public keys, and inspect billing balances.

Authentication relies on a browser-based device login. You authorize the request at `auth.osir.com`, binding the session exclusively to the active chat. Sessions drop after 30 minutes of inactivity. For local hosting, the Quarkus application strictly requires Java 21.
