Setup
Install Namecheap in your MCP client (Claude Desktop, Cursor, Windsurf, and others).
Repository: https://github.com/johnsorrentino/mcp-namecheap
Follow the installation instructions in the repository README, then restart your MCP client.
I only added the functionality I use and I don't think it's a good idea to allow an agent to register domains. The complete set of Namecheap API methods can be foundhere.
- Get Domain List: Retrieve all domains in your Namecheap account
- Check Domain Availability: Check if domains are available for registration
- Set Custom DNS: Configure custom nameservers for your domains
- Configurable Tools: Enable/disable specific tools to control what's available in Cursor
- At least 20 domains under your account
- $50 on your account balance
- $50 spent within the last 2 years
- Enable API access in your Namecheap dashboard
- Obtain your API key
- Whitelist your IP address
git clone <repository-url> cd mcp-namecheap
Create a.envfile with your Namecheap credentials:
NAMECHEAP_API_USER=your_api_username NAMECHEAP_API_KEY=your_api_key NAMECHEAP_USERNAME=your_namecheap_username NAMECHEAP_CLIENT_IP=your_whitelisted_ip_address
Or reference themcp-config.jsonfile which shows all available environment variables.
You can enable/disable specific tools by setting these environment variables:
- NAMECHEAP_ENABLE_GETLIST- Enable domain list retrieval (default: true)
- NAMECHEAP_ENABLE_CHECK- Enable domain availability checking (default: true)
- NAMECHEAP_ENABLE_SETCUSTOM- Enable custom DNS configuration (default: true)
Set any of these tofalseto disable the corresponding tool.
For testing, you can use Namecheap's sandbox environment:
1. Get Domain List (namecheap_get_domain_list)
Returns a list of all domains in your Namecheap account with details including expiration dates, auto-renewal status, and DNS configuration.
2. Check Domain Availability (namecheap_check_domain_availability)
Checks the availability of one or more domains for registration.
- domains(array): Array of domain names to check (e.g., ["example.com", "test.org"])
3. Set Custom DNS (namecheap_set_custom_dns)
Sets custom nameservers for a domain. Note that services like URL forwarding, email forwarding, and dynamic DNS will not work with custom nameservers.
- domain(string): The domain name (e.g., "example.com")
- nameservers(array): Array of nameserver addresses (1-12 nameservers)
To use this server with an MCP client like Cursor, add the following to your MCP configuration:
{ "mcpServers": { "namecheap": { "command": "node", "args": ["path/to/mcp-namecheap/dist/index.js"], "env": { "NAMECHEAP_API_USER": "your_api_username", "NAMECHEAP_API_KEY": "your_api_key", "NAMECHEAP_USERNAME": "your_namecheap_username", "NAMECHEAP_CLIENT_IP": "your_whitelisted_ip_address" } } } }

This server uses the following Namecheap API endpoints:
- namecheap.domains.getList- Retrieve domain list
- namecheap.domains.check- Check domain availability
- namecheap.domains.dns.setCustom- Set custom nameservers
For more information, see theNamecheap API documentation.
The server includes comprehensive error handling for:
- Missing or invalid API credentials
- Network connectivity issues
- Namecheap API errors
- Invalid parameters
- Disabled tools
- Store API credentials securely
- Keep your IP whitelist updated
- Use environment variables for sensitive configuration
- Consider using the sandbox environment for testing
