Domain search MCP server, free

Find a free domain without leaving your assistant.

Add one address to Claude, ChatGPT, Gemini or your code editor. Then ask in plain words: it checks every ending, gives the price and renewal, and hands you a link to register.

I'm starting a design studio called Brightfield. Which domains can I get?
Searching brightfield across 7 endings
The .com and .net are taken, but these are free:
brightfield.co$38.48 renews $45.48Register
brightfield.studio$51.68 renews $68.68Register
brightfield.dev$16.18 renews $21.18Register
brightfield.comTakenTaken
For a studio, brightfield.studio says what you do. Want me to check a few more names in case you'd like a .com?

No name yet? Describe what you do.

You get a short list of names that fit, and every one is already checked: each is free to register right now, with its price and renewal beside it.

In your assistant, ask: Suggest free names for a yoga studio in Chiang Mai Only names that are free right now are shown

Set up once, then just ask.

There is nothing to install and nothing to sign up for. Your assistant does the searching; you choose the name.

1 Add the address

Paste the server address into your assistant as a connector. The walkthrough for each one takes about a minute.

2 Ask in plain words

Name a domain, a name without an ending, or just describe your business. It checks every ending you care about.

Is brightfield.studio free, and what does it renew at?
3 Register from the link

Every free name comes with its price and a link straight to checkout for that exact name.

Five tools your assistant can use.

The same answers come back whether you ask in a chat, use the search on this page, or call the API.

check_domainsExact domains, up to 50 at once: free or taken, with prices.
search_nameOne name across many endings, free first and cheapest first.
suggest_namesNames for a business you describe, every one already free.
domain_detailsWho holds a taken domain, when it was registered and when it expires.
ending_pricesFirst-year and renewal prices for any ending, side by side.
Free or takenChecked with the registry for that ending, or the registrar where the registry has no lookup.
ConfirmedSays whether the registry has answered yet. A name shown as free while it is still being confirmed says so.
First year and renewalBoth prices in US dollars, and the fewest years an ending is sold for, such as two for .ai.
Premium namesMarked as premium, with no list price, because their registry sets the price.
Taken namesRegistrar, registration date, expiry date and nameservers, when the registry publishes them.
Register linkA short link to checkout for that exact name, on every free result.

What the popular endings cost.

The first year is often a promotion. The renewal is what you pay every year after, so it is shown beside it.

Questions people ask.

Anything else, ask on the support page and we answer there.

Is it really free?

Yes. Searching, the MCP server and the API cost nothing and need no account. When you register a name through one of our links we may earn a small commission, at no extra cost to you.

How current are the answers?

Each name is checked when you ask. A free answer is reused for up to 10 minutes and a taken one for up to 12 hours, so a popular name does not slow anyone down.

What does "confirming" mean?

DNS showed the name has no owner, and the registry has not answered yet. It is very likely free; ask again after a minute for the registry's own answer.

Do you register the domain for me?

No. The Register link opens checkout for that exact name at the registrar, and the domain is registered in your own name and account.

Which assistants work?

Any that can add an MCP server: Claude, ChatGPT, Gemini, Claude Code, Cursor, VS Code with Copilot, Windsurf and others. Each has a short walkthrough.

Is there a limit?

60 names a minute and 2,000 a day from each address, or each assistant session. That is plenty for finding a name; it only stops bulk scraping.

Add it to your assistant now.

One address, no key and no sign-in. Next time you need a name, just ask.
