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.

Scope	Access

`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)

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.

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].
