Common Use Cases

For AI-Powered Domain Management

Use this Domain MCP server to manage your Dynadot domains through natural language with AI assistants:

Domain Operations

• "Check if example.com is available and show me similar domains"
• "Register example.com and enable WHOIS privacy"
• "Show me all domains expiring in the next 30 days"

DNS Management

• "Set up DNS for mysite.com with A record pointing to my server"
• "Add www subdomain and configure MX records for email"
• "Update DNS to point to Cloudflare nameservers"

Bulk Operations

• "Enable auto-renewal for all my .com domains"
• "Lock all domains to prevent unauthorized transfers"
• "Search pricing for .com, .net, .io, and .ai domains"

Advanced Automation

• "Create a contact and use it to register multiple domains"
• "Transfer example.com from another registrar with auth code"
• "Set up domain forwarding from old-site.com to new-site.com"

Why Use an MCP Domain Server?

Traditional domain management requires:

• Memorizing API documentation
• Writing custom scripts
• Manual navigation through control panels

With this Domain MCP integration:

• ✅ Natural language: Just describe what you want
• ✅ AI assistance: Claude/Cursor understand domain concepts
• ✅ Context aware: AI remembers your account structure
• ✅ Faster workflow: No context switching to web UI

Quick Installation

Prerequisites

You'll need a Dynadot account and an API key to use this MCP server.

Method 1: NPX (Recommended) ⚡

No installation needed! NPX runs the package directly from npm.

Step 1: Get your API key from Dynadot Account Settings

Step 2: Add to your MCP client config:

Claude Code - Click to expand

Edit ~/.claude/mcp.json:

{
  "mcpServers": {
    "domain-mcp": {
      "command": "npx",
      "args": ["-y", "domain-mcp"],
      "env": {
        "DYNADOT_API_KEY": "your-api-key-here"
      }
    }
  }
}

Or use the CLI:

claude mcp add domain-mcp

Cursor - Click to expand

Edit ~/.cursor/mcp.json (macOS/Linux) or %APPDATA%\Cursor\mcp.json (Windows):

{
  "mcpServers": {
    "domain-mcp": {
      "command": "npx",
      "args": ["-y", "domain-mcp"],
      "env": {
        "DYNADOT_API_KEY": "your-api-key-here"
      }
    }
  }
}

Restart Cursor after editing.

Claude Desktop - Click to expand

Edit the config file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "domain-mcp": {
      "command": "npx",
      "args": ["-y", "domain-mcp"],
      "env": {
        "DYNADOT_API_KEY": "your-api-key-here"
      }
    }
  }
}

Restart Claude Desktop after editing.

Step 3: Restart your AI assistant and start using domain commands!

Method 2: Global Install

Install globally with npm:

npm install -g domain-mcp

Then use domain-mcp instead of npx -y domain-mcp in your config:

{
  "mcpServers": {
    "domain-mcp": {
      "command": "domain-mcp",
      "env": {
        "DYNADOT_API_KEY": "your-api-key-here"
      }
    }
  }
}

Method 3: Local Development

For contributing or customization:

git clone https://github.com/joachimBrindeau/domain-mcp.git
cd domain-mcp
npm install
npm run build

Then configure with absolute path:

{
  "mcpServers": {
    "domain-mcp": {
      "command": "node",
      "args": ["/absolute/path/to/domain-mcp/dist/index.js"],
      "env": {
        "DYNADOT_API_KEY": "your-api-key-here"
      }
    }
  }
}

Configuration Options

API Quirks & Known Issues

edit_contact

Dynadot API requires ALL contact fields to be provided when editing, not just the fields you want to change. Partial updates will fail with "missing email" or similar errors.

Solution: Always provide complete contact data:

await client.execute('edit_contact', {
  contact_id: '12345',
  name: 'Updated Name',
  email: 'email@example.com',
  phonecc: '1',
  phonenum: '5551234567',
  address1: '123 Street',
  city: 'City',
  state: 'CA',
  zip: '94102',
  country: 'US'
});

lock_domain unlock

The lock_domain unlock command may return a misleading error "this domain has been locked already" when attempting to unlock. This appears to be either:

• Domain protection preventing API unlock
• A bug in the Dynadot API error messaging

Unlocking domains may need to be done through the Dynadot control panel.

Frequently Asked Questions

What is an MCP server for domains?

A Domain MCP server is a Model Context Protocol server that enables AI assistants like Claude and Cursor to manage domains through natural language. Instead of using a web interface or writing API code, you simply ask your AI assistant to perform domain operations.

How is this different from using the Dynadot website?

The Domain MCP server brings domain management into your AI assistant's context:

• Natural language: "Register example.com" vs clicking through multiple pages
• AI understanding: The assistant knows your account structure and suggests related actions
• Workflow integration: Manage domains while coding, writing, or working without leaving your editor
• Automation ready: Chain multiple domain operations in one conversation

Which AI assistants work with this Domain MCP server?

This MCP server works with any MCP-compatible AI assistant:

• Claude Code - Anthropic's official CLI
• Cursor - AI-powered code editor
• Claude Desktop - Anthropic's desktop app
• Any other client supporting the Model Context Protocol

Do I need to know the Dynadot API?

No! That's the power of the Domain MCP approach. Your AI assistant handles the API complexity. Just describe what you want in natural language.

Is this safe to use with production domains?

Yes, with proper precautions:

• Sandbox mode: Test with DYNADOT_SANDBOX=true first
• Review actions: The AI shows you what it will do before executing
• API limits: Dynadot's API rate limits prevent runaway operations
• Audit trail: All operations are logged in your Dynadot account

How much does it cost?

The Domain MCP server itself is free and open source (MIT license). You only pay for Dynadot domain services and your AI assistant subscription.
