MCP Namecheap Server

A Model Context Protocol (MCP) server that provides integration with the Namecheap API for domain management operations.

Features

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 found here.

• 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

Development

Scripts

• npm run build - Build the TypeScript project
• npm run dev - Run in development mode with tsx
• npm start - Run the built project

API Reference

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 the Namecheap API documentation.

Error Handling

The server includes comprehensive error handling for:

• Missing or invalid API credentials
• Network connectivity issues
• Namecheap API errors
• Invalid parameters
• Disabled tools

Security Considerations

• Store API credentials securely
• Keep your IP whitelist updated
• Use environment variables for sensitive configuration
• Consider using the sandbox environment for testing

Prerequisites

Before using this MCP server, you need:

1. Namecheap Account Requirements:

   • At least 20 domains under your account
   • $50 on your account balance
   • $50 spent within the last 2 years

2. API Access Setup:

   • Enable API access in your Namecheap dashboard
   • Obtain your API key
   • Whitelist your IP address

Installation

1. Clone this repository:

git clone <repository-url>
cd mcp-namecheap

2. Install dependencies:

npm install

3. Build the project:

npm run build

Configuration

Create a .env file 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 the mcp-config.json file which shows all available environment variables.

Tool Configuration

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 to false to disable the corresponding tool.

Sandbox Mode

For testing, you can use Namecheap's sandbox environment:

NAMECHEAP_SANDBOX=true

Usage

Running the Server

npm start

Available Tools

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.

Parameters: None

2. Check Domain Availability (namecheap_check_domain_availability)

Checks the availability of one or more domains for registration.

Parameters:

• 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.

Parameters:

• domain (string): The domain name (e.g., "example.com")
• nameservers (array): Array of nameserver addresses (1-12 nameservers)

MCP Client Configuration

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"
      }
    }
  }
}
