MCP server docs
Connect Just Domain to Claude, ChatGPT, Cursor, or any MCP-compatible AI assistant. Two read-only tools: search domain availability and pricing, and check whether a domain held elsewhere could move here.
Confirm your email
Every domain needs a confirmed email address for the owner. We send one link. One click does it. This page covers 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 (search_domains) and your assistant returns live availability plus a checkout link - the user completes registration in the browser.
check_domain_transfer - the transfer check for agents
The Just Domain MCP tool that answers whether a domain held at another registrar could move: what blocks it, whether its DNS survives, and the full-term price. Read-only, unauthenticated, and it never returns an authorization code.
