# Registrar Domains
> Find a domain. Keep it for less. A domain registrar with a search on the website and the same tools as an MCP server and a REST API.

MCP endpoint: https://registrar-domains.com/mcp (Streamable HTTP, stateless; open tools, account tools with a bearer API key)
MCP endpoint with sign-in: https://registrar-domains.com/mcp/oauth (OAuth 2.1, for Claude.ai and ChatGPT connectors and Claude Code)
OpenAPI: https://registrar-domains.com/openapi.json
Docs: https://registrar-domains.com/docs
Price comparison: https://registrar-domains.com/compare (JSON: https://registrar-domains.com/compare.json)

## Tools
- check_domain: Is this exact domain available? Answers available, taken, or unknown.
- suggest_domains: Try one idea across the launch TLDs and rank by availability.
- get_price: First-year and renewal price in EUR for one TLD, next to our registrar costs.
- register_domain: Start a registration. Needs an API key or a signed-in connection. Answers an order with a payment link for the human; the domain is registered once payment clears.
- get_order: Follow an order: awaiting_payment, paid, registering, registered, failed, refunded.
- list_domains: The domains of your account, with state and expiry.
- list_orders: The orders of your account, newest first, from every key and connection.

## Availability answers
available | taken | unknown. Unknown is never available.

Cheaper to renew than Namecheap, Gandi and IONOS on every TLD above (ids: namecheap, gandi, ionos). Not the cheapest everywhere: Cloudflare and Porkbun often renew for less. Sources and ranking per TLD at /compare.json.

## Status
Checks and prices are open without a key. register_domain, get_order, list_domains and list_orders need an account: Authorization: Bearer <api key> on /mcp, or sign-in on /mcp/oauth. register_domain answers an order with checkoutUrl for the human to pay. Follow it with get_order. Nothing is registered or charged before payment. All sales are final once registered.
A person gets an API key by signing in with an email code at https://registrar-domains.com/signin and creating one under Connect agent.
A person without a key can buy on the website: search, press Buy, fill in the registrant, pay. That route has an anti-bot check and is not for agents.
