The Unstoppable Domains MCP (Model Context Protocol) server enables you to search, purchase, and manage domain names through natural conversation inside ChatGPT, Claude, or using automated AI agents. This guide explains how to connect an AI agent to your Unstoppable Domains account and setup permissions for various interactions.

What Can You Do?

With the MCP server, you can ask AI assistants to:

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 records, CNAME, MX, TXT, and other DNS records
Sell on Marketplace - List domains for sale, manage offers, negotiate with buyers
Communicate - Contact domain sellers and manage conversations

Getting Started

Connecting via OAuth (Recommended)

Most MCP-compatible tools support OAuth 2.0 authentication. These tools follow the general approach below to add a custom MCP connection:

Add the Unstoppable Domains MCP server URL to your AI tool. See the table below for specific instructions for each tool.
```
https://api.unstoppabledomains.com/mcp/v1
```
When prompted, authenticate via your browser
Authorize the requested permissions
Start a chat to manage your domains using natural language

Manage your connections: Go to Account Settings to view connected apps, their scopes, and disconnect if needed.

Authentication Options

OAuth 2.0 (Recommended)

OAuth provides scoped access through browser-based authentication:

Easy setup - Just authenticate when prompted using your Unstoppable Domains account
Granular permissions - Only grant access to what you need
Revocable - Disconnect apps anytime from Account Settings

Available scopes:

Scope	Access
`domains:search`	Search domains, check availability
`portfolio:read`	View your domains, DNS records, offers
`portfolio:write`	Manage DNS, create listings, send messages
`cart:read`	View cart and payment methods
`cart:write`	Add/remove cart items
`checkout`	Complete purchases

API Key (Advanced)

For manual configuration or custom integrations:

Go to Account Settings
Scroll to bottom and click Advanced
Find the MCP API Key section
Generate a key (format: ud_mcp_*)
Copy your key (available anytime from this page)
Use the key in the Authorization header:

Authorization: Bearer ud_mcp_your_key_here

Security tip: Store your API key in an environment variable to avoid exposing it in shell history or process listings:

export UD_MCP_API_KEY="ud_mcp_your_key_here"
# Then reference $UD_MCP_API_KEY in your scripts or configuration

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