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

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:

2. Install dependencies:

3. Build the project:

Configuration

Create a .env file with your Namecheap credentials:

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:

Usage

Running the Server

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

Security Considerations

• Store API credentials securely

• Keep your IP whitelist updated

• Use environment variables for sensitive configuration

• Consider using the sandbox environment for testing
