# MCP Server

The Unstoppable Domains MCP (Model Context Protocol) server lets you access the [User API](/mcp/overview) through natural conversation inside ChatGPT, Claude, or using automated AI agents.

## Quick Start

Point your AI tool at the Unstoppable Domains MCP server URL:

When prompted, authenticate with your Unstoppable Domains account via OAuth. That's it — start chatting to manage your domains. See the setup instructions below for your specific tool.

## Setup Instructions

### ChatGPT

#### Option 1: Use our Custom GPT (Easiest)

The fastest way to get started with ChatGPT is our pre-built **[Unstoppable Domains GPT](https://chatgpt.com/g/g-698a7d3768448191a7177d7f3f22a130-unstoppable-domains)**. Just open the link and start chatting.


#### Option 2: Add the MCP Server to ChatGPT

Connecting the MCP server directly gives you access to all available tools. Requires ChatGPT Plus, Pro, Team, or Enterprise. These steps must be completed in the [ChatGPT web app](https://chatgpt.com).

**1. Enable Developer Mode**

Open [ChatGPT's connector settings](https://chatgpt.com/#settings/Connectors/Advanced) and enable **"Developer Mode (beta)"** under Advanced Settings.

**2. Create a Connector**

Navigate back to the main Connectors page and click **"Create"**. Paste the MCP server URL:

Leave authentication as the default setting and click **Save**.

**3. Verify Installation**

Start a new conversation and ask ChatGPT to search for a domain. When prompted, authorize the connection with your Unstoppable Domains account.

### Claude (Desktop & Web)

Claude supports MCP connectors on both the desktop app and [claude.ai](https://claude.ai). The setup is the same for both.

#### For Paid Plans (Pro, Max, Team, Enterprise)

1. Open **Settings** (click your name in the bottom-left corner)
2. Select **Connectors**
3. Click **"Add custom connector"** at the bottom of the list
4. Enter the MCP server URL:

5. Click **"Add"**
6. When prompted, sign in with your Unstoppable Domains account to authorize access

To use the connector in a conversation, click the **"+"** button in the compose area, select **"Connectors"**, and toggle on Unstoppable Domains.

#### For Free Plans (Desktop App Only)

Free users can connect via the JSON configuration file:

1. Open Claude Desktop and go to **Claude** (menu bar) → **Settings** → **Developer** → **Edit Config**

This opens the config file at:
- **macOS:** `~/Library/Application Support/Claude/claude_desktop_config.json`
- **Windows:** `%APPDATA%\Claude\claude_desktop_config.json`

2. Add the following configuration:

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

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

Authorization: Bearer ud_mcp_your_key_here

**Step 2: Commit**

```bash
git add mcp/mcp-server.md
git commit -m "Add dedicated MCP Server page with setup and auth content"

# User API

The Unstoppable Domains User API provides programmatic access to manage domain names, DNS, and the marketplace. You can integrate it directly via REST or use it through AI assistants via the [MCP Server](mcp-server).

## What Can You Do?

The User API supports the full domain lifecycle:

- **Search & Purchase Domains** — Find available domains, check pricing, and complete purchases
- **Manage Your Portfolio** — View your domains, filter by status, track expirations
- **Configure DNS** — Set up A, AAAA, CNAME, MX, TXT, NS, SRV, and CAA records
- **Sell on Marketplace** — List domains for sale, manage offers, negotiate with buyers
- **Communicate** — Contact domain sellers and manage conversations

For a full list of operations, see the [API Reference](/apis/mcp/openapi).

## Authentication

The User API supports two authentication methods:

- **OAuth 2.0 (Recommended)** — Browser-based authentication with granular scopes. Authenticate when prompted using your Unstoppable Domains account.
- **API Key** — For scripts and custom integrations. Generate a key from [Account Settings](https://unstoppabledomains.com/account/settings?tab=advanced).

Both methods use a Bearer token in the `Authorization` header. See the [MCP Server](mcp-server) page for detailed setup and scope reference.

## MCP Server

The [MCP Server](mcp-server) wraps the User API in the Model Context Protocol, letting you access the same functionality through natural conversation inside ChatGPT, Claude, and other AI tools.

See [MCP Server setup and usage](mcp-server) to get started.
