InstaDomain
Domain registration for AI agents. Check availability, buy domains, and configure DNS without leaving your terminal.
InstaDomain is an MCP server that lets AI coding assistants (Claude Code, Cursor, Windsurf) register domains on your behalf. Pay with Stripe or x402 (USDC on Base). Domains are registered in your name with Cloudflare DNS auto-configured.
Why?
You're building a project in Claude Code. You need a domain. Today you alt-tab to Namecheap, search, add to cart, fill out forms, configure DNS. That's 10 minutes of context-switching.
With InstaDomain, your AI agent checks availability, shows you the price, and buys it in one conversation. DNS is ready before you finish your next prompt.
Features
- Check domains - single domain with pricing, bulk check up to 50, or AI-generated suggestions
- Buy domains - Stripe checkout (card) or x402 (USDC on Base, no signup required)
- Automatic DNS - Cloudflare zone created with scoped API token returned to you
- Your domain, your name - registered as your property, not ours
- Transfer out anytime - EPP auth codes and domain unlock built in
- Auto-renew - enabled by default, renew via Stripe
- WHOIS privacy - enabled by default

x402 Crypto Payments
InstaDomain accepts x402 payments in USDC on Base. No signup, no API keys. Your AI agent pays directly from a wallet.
This enables fully autonomous agents to register domains without human payment intervention.
