Domain-MCP
A simple MCP server that lets AI assistants help you with domain research - checking availability, looking up WHOIS info, finding expired domains, and more.
No API keys needed. Everything works out of the box.
What it does
- Check domain availability - See if a domain is available to register
- WHOIS lookup - Get registration info, expiration dates, registrar details
- DNS records - Look up A, MX, TXT, and other DNS records
- SSL certificates - Check SSL cert info and expiration
- Find expired domains - Search for recently expired or deleted domains
- Domain age - See how old a domain is
- Bulk checks - Check multiple domains at once
Quick Start
# Install uv (if you don't have it)
pip install uv

cd domain-mcp
# Set up and install

Using with Claude Desktop
Add this to your Claude Desktop config:
{
"mcp-servers": {
"domain-mcp": {
"command": "python",
"args": ["/path/to/domain-mcp/main.py", "--transport", "stdio"]
}
}
}
Example Usage
Just ask Claude things like:
- "Is mydomain.com available?"
- "Show me WHOIS info for google.com"
- "Find expired domains with 'tech' in the name"
- "What are the DNS records for example.com?"
How it works
Uses free, public APIs and services:
- RDAP for WHOIS data (no auth needed)
- Cloudflare DNS over HTTPS
- crt.sh for SSL certificates
- Public domain databases
Everything is fetched fresh when you ask - no caching, always current data.
