Namecheap MCP Server

An MCP (Model Context Protocol) server that provides tools for interacting with the Namecheap domain registration API. Check domain availability, get pricing, and register domains through Claude Desktop or any MCP-compatible client.

⚠️ Important Security Warning

This tool uses the Namecheap live API by default and can make REAL purchases that will charge your Namecheap account. Always double-check domain registration commands before confirming purchases.

Features

• 🔍 Domain Availability Check - Instantly check if a domain name is available
• 💰 TLD Pricing - Get current pricing for any top-level domain
• 🛒 Domain Registration - Register domains with WhoisGuard privacy protection
• 🔒 Secure API Integration - Uses Namecheap's secure API with IP whitelisting
• 🧪 Sandbox Mode - Test without making real purchases

Prerequisites

• Namecheap account with API access enabled
• Your IP address whitelisted in Namecheap

Namecheap API Requirements

To use the Namecheap API, your account must meet one of these requirements:

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

Installation

You can run this MCP server using npx without installing it locally:

Configuration

Claude Desktop

Add the following to your Claude Desktop configuration:

{
  "mcpServers": {
    "namecheap": {
      "command": "npx",
      "args": ["-y", "@webdevtoday/nc-mcp-server"],
      "env": {

      }
    }
  }
}

To find your Claude Desktop configuration:

1. Open Claude Desktop
2. Go to Settings → Developer → Edit Config

Setting up Registrant Profile

For domain registration, you'll need to provide registrant contact information. You can do this in two ways:

1. Environment Variable (Recommended for npx): Add a REGISTRANT_PROFILE environment variable with JSON data:

   {
     "mcpServers": {
       "namecheap": {
         "command": "npx",
         "args": ["-y", "@webdevtoday/nc-mcp-server"],
         "env": {
           "NC_USERNAME": "your_username",
           "NC_API_KEY": "your_api_key",
           "NODE_ENV": "production",
           "REGISTRANT_PROFILE": "{\"firstName\":\"John\",\"lastName\":\"Doe\",\"address1\":\"123 Main St\",\"city\":\"New York\",\"stateProvince\":\"NY\",\"postalCode\":\"10001\",\"country\":\"US\",\"phone\":\"+1.2125551234\",\"email\":\"[email protected]\"}"
         }
       }
     }
   }

2. Local File: If running locally, create a registrant-profile.json file in your working directory.

Whitelisting Your IP

1. Find your IP address:

   curl ifconfig.me

2. Log in to Namecheap
3. Go to Profile → Tools → API Access
4. Add your IP to the whitelist
