How to Set Up and Use Domain Tools
The Domain Tools MCP Server gives AI clients like Claude a set of DNS and domain analysis capabilities without requiring any external API keys — it queries public DNS resolvers and WHOIS databases directly. It exposes tools for WHOIS lookups (registrar, expiration date, nameservers), DNS record queries (A, AAAA, MX, NS, TXT, CNAME, SOA), DNS health checking for configuration problems, and a comprehensive combined domain analysis. Sysadmins, security researchers, and developers can use it to investigate domain ownership, troubleshoot DNS propagation, or verify domain configurations through conversational prompts.
Prerequisites
- Python 3.13 or higher recommended (3.8+ minimum)
- Internet connectivity for DNS resolver and WHOIS queries
- pip for installing Python packages
- An MCP-compatible client such as Claude Desktop
Clone the repository
Download the domain-tools-mcp-server source code to your local machine.
git clone https://github.com/deshabhishek007/domain-tools-mcp-server.git
cd domain-tools-mcp-serverCreate and activate a virtual environment
Isolate the server's dependencies from your system Python installation.
python3 -m venv domain-tools-env
source domain-tools-env/bin/activateInstall dependencies
Install the required packages: mcp for the protocol layer, dnspython for DNS queries, and python-whois for WHOIS lookups.
pip install -r requirements.txt
# Or manually:
pip install mcp dnspython python-whois pydanticConfigure your MCP client
Add the server to your Claude Desktop configuration. Use the full path to the virtual environment's Python executable to ensure the correct packages are loaded.
{
"mcpServers": {
"domain-tools": {
"command": "/path/to/domain-tools-env/bin/python",
"args": ["/path/to/domain-tools-mcp-server/server.py"]
}
}
}Restart Claude Desktop
Quit and relaunch Claude Desktop to load the new server configuration. The domain tools will now be available in your conversations.
Domain Tools Examples
Client configuration
Claude Desktop configuration for the Domain Tools MCP server using a virtual environment Python path.
{
"mcpServers": {
"domain-tools": {
"command": "/Users/yourname/domain-tools-mcp-server/domain-tools-env/bin/python",
"args": ["/Users/yourname/domain-tools-mcp-server/server.py"]
}
}
}Prompts to try
Example prompts to use the domain analysis tools in Claude.
- "Do a WHOIS lookup for github.com and tell me when it expires."
- "Query the DNS records for example.com — I need the A, MX, and TXT records."
- "Run a DNS health check on mydomain.com and flag any configuration problems."
- "Give me a complete domain analysis for cloudflare.com including registration info and all DNS records."Troubleshooting Domain Tools
WHOIS lookup returns empty or partial results
Some domain registrars rate-limit or restrict WHOIS queries. Try increasing WHOIS_TIMEOUT in your environment, or query again after a short delay. Privacy-protected domains may return minimal registrant data by design.
DNS query fails or times out
The server uses public DNS resolvers (e.g., 8.8.8.8). Check your internet connectivity and firewall rules for outbound UDP/TCP port 53. You can adjust DNS_TIMEOUT and DNS_LIFETIME settings in the server configuration.
'No module named dnspython' or similar import error
The Claude Desktop config must point to the virtual environment's Python binary, not the system Python. Verify the 'command' path by running '/path/to/domain-tools-env/bin/python -c "import dns"' in your terminal.
