Unstoppable Domains MCP Server

Search, register, and manage domain names through natural conversation with AI assistants.

The Unstoppable Domains MCP server lets you access the User API through natural conversation inside ChatGPT, Claude, Cline, or any MCP-compatible agent.

Endpoint: https://api.unstoppabledomains.com/mcp/v1

Quick Start

Claude Code

claude mcp add --transport http unstoppable-domains https://api.unstoppabledomains.com/mcp/v1

Then run /mcp inside a session and follow the OAuth flow to authenticate.

To make it available across all projects:

claude mcp add --transport http --scope user unstoppable-domains https://api.unstoppabledomains.com/mcp/v1

Claude Desktop (free plan)

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "unstoppable-domains": {
      "command": "npx",
      "args": ["mcp-remote", "https://api.unstoppabledomains.com/mcp/v1"]
    }
  }
}

Restart Claude Desktop and look for the hammer icon in the chat input.

What You Can Do

Ask your AI assistant things like:

• "Is 'mycoolstartup.com' available? What about .ai and .io?"
• "Register acme.com and set up Google Workspace DNS"
• "List my domains expiring in the next 90 days"
• "Create a marketplace listing for mydomain.com at $5,000"
• "Show me all DNS records for example.com and add an MX record"
• "Generate an AI landing page for parkeddomain.com"

Authentication

OAuth 2.0 (Recommended)

When prompted by your AI tool, sign in with your Unstoppable Domains account. OAuth grants only the scopes you approve and can be revoked anytime from Account Settings.

API Key (Advanced)

Generate a key at Account Settings → Advanced → MCP API Key. Keys use the ud_mcp_* format.

export UD_MCP_API_KEY="ud_mcp_your_key_here"

Use as a Bearer token: Authorization: Bearer ud_mcp_your_key_here

Note: API keys grant full access to all tools. Use OAuth for scoped access.
