Install in your AI tool
The domain registrar for businesses built with AI. Add Just Domain to the AI tool you use, at https://mcp.justdomain.ai/.
MCP server docs
Connect Just Domain to Claude, ChatGPT, Cursor or any MCP assistant. Three read-only tools: availability and pricing, a transfer check, a trademark check.
Confirm your email
Every domain needs a confirmed owner email. We send one link; one click does it. What that email is, what the dates mean, and what to do if you cannot find it.
How AI assistants search domains
ChatGPT and Claude can't check domain availability on their own. Connect the Just Domain MCP and your assistant returns live availability plus a checkout link.
check_domain_transfer - the transfer check for agents
The Just Domain MCP tool that answers whether a domain at another registrar could move: what blocks it, if its DNS survives, and the full-term price. Read-only.
