OSIR Domain Registrar — Claude Code MCP server: install and usage
Connects AI assistants to the OSIR infrastructure. Enables domain registration, DNS editing, and VPS provisioning straight from your coding chat.
claude mcp add --transport http domain-registrar https://be.osir.com/mcp/httpWhat OSIR Domain Registrar 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.
What it helps with
- check domain availability and find prefix alternatives
- configure DNS records and email routing for a site
- deploy a virtual server with preinstalled SSH credentials
- review expiring domains and manage renewals
Example prompts for the agent

- List every domain in my account that expires within a month
