Overview

AI-generated overview

Remote MCP server for Unstoppable Domains that lets an assistant search, register, configure DNS for, list and buy domain names.

What you can do
  • Search domains and TLDs, check availability and expired names, and look up knowledge base articles
  • List portfolio domains, ICANN contacts, pending operations, backorders and auto-renewal settings
  • Manage DNS records, nameservers, DNS hosting and reusable DNS presets
  • Create, update and cancel marketplace listings, review offers and reply to buyer leads
  • Fill the cart, view payment methods and complete checkout
  • Generate, upload and remove AI landing pages and check AI credits
When to use it
Useful when you want to research and buy domain names, manage DNS for domains you own, or run marketplace listings and buyer conversations from inside an AI assistant without switching to the web dashboard.
Requirements
Remote streamable HTTP endpoint; no local package needed. Requires an Unstoppable Domains account and OAuth sign-in with approved scopes, or alternatively an MCP API key sent as a Bearer token. Network access to the Unstoppable Domains API is required.
Before you install
The server can spend money: checkout, cart changes, backorders and AI credits are real purchases. It also writes and deletes data, including DNS records, nameserver settings, listings and domain pushes. API keys grant full access to all tools, so OAuth with limited scopes is safer. Searches, portfolio data, DNS records and purchase actions are sent to Unstoppable Domains, and ICANN registration data is shared with the relevant registry.

Installation

In SourceWeft

  1. Open Unstoppable Domains in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.unstoppabledomains%2Fmcp-server/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

Unstoppable Domains MCP Server

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

[MCP] [License] [Tools] [Auth]

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

bash
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:

bash
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):

json
{  "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.

Claude Desktop / Claude.ai (paid plans)

  1. Open Settings → Connectors → Add custom connector
  2. Paste: https://api.unstoppabledomains.com/mcp/v1
  3. Click Add and authorize with your Unstoppable Domains account

ChatGPT

  1. Open ChatGPT Connector Settings and enable Developer Mode (beta)
  2. Create a new connector with URL: https://api.unstoppabledomains.com/mcp/v1
  3. Authorize with your Unstoppable Domains account

Or use the pre-built Unstoppable Domains GPT (core features, no MCP config needed).

Cline / Cursor / other MCP clients

json
{  "unstoppable-domains": {    "type": "http",    "url": "https://api.unstoppabledomains.com/mcp/v1/"  }}

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.

ScopeAccess
domains:searchSearch domains, check availability
portfolio:readView your domains, DNS records, offers
portfolio:writeManage DNS, create listings, send messages
cart:readView cart and payment methods
cart:writeAdd/remove cart items
checkoutComplete purchases

API Key (Advanced)

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

bash
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.

Privacy & Data Practices

Data collected: When you use this MCP server, requests are processed by Unstoppable Domains servers. This includes domain names you search, portfolio data you query, DNS records you read or modify, and any purchase or marketplace actions you initiate.

Data storage: Unstoppable Domains stores account data, domain registrations, DNS records, and transaction history as required to provide the service. Conversation content from your AI assistant is not stored by Unstoppable Domains — only the API requests your assistant generates are received.

Data sharing: Unstoppable Domains does not sell personal data. Registration data for ICANN TLDs (.com, .net, .org, etc.) is shared with the relevant registry per ICANN policy. Payment processing is handled by third-party processors under their own privacy policies.

Data retention: Account and domain data is retained for the duration of your account and as required by law. You may request deletion of your account data via [email protected].
