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 # Clone the repo git clone https://github.com/yourusername/domain-mcp.git cd domain-mcp # Set up and install uv venv source .venv/bin/activate # On Windows: .venv\Scripts\activate uv pip install -e . # Run it python main.py

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.
