If you’re a developer or founder today, you probably use Cursor to write code and Claude to refactor architecture. But when you need to check domain availability or look up DNS records, you still have to open a browser, navigate to a WHOIS tool, solve a CAPTCHA, and manually parse the results.
We think domain intelligence should work the way everything else does now: through conversation and API. That’s why we built DomainKits GPTs and MCP Server.
1. The GPTs: Conversational Discovery
We started by bringing our data directly into ChatGPT. We realized that domain search is often fuzzy—you don’t always know the exact keyword, but you know the intent.
Our AI Domain Finder GPT allows you to describe a vision (“I need an aged domain for a crypto project”) rather than just guessing keywords. Because it connects to our real-time availability engine, it doesn’t just hallucinate names; it finds assets you can actually buy/register.
For security researchers and investors, we built the NS Reverse Lookup GPT. This tool allows you to trace infrastructure footprints. You can ask it to find “all 3-letter .com domains pointing to Afternic nameservers,” and it performs a deep infrastructure query instantly.
2. The Integration: MCP for Developers
We’ve released an open-source MCP Server that connects Claude Desktop, Cursor, or your own AI agents to DomainKits data. This lets your AI assistant verify domain availability, check DNS records, and run bulk lookups without leaving your IDE.
The MCP Server is free to use today, no API key needed. Clone the repo, connect to Claude Desktop, and start querying.
The free tier has data caps and result limits. We’re building a subscription tier for users who need larger datasets, higher concurrency, and access to forensic/monitoring tools. Details coming soon. The DomainKits Platform is where the deep historical data and enterprise-grade monitoring live.
