LABSCO SUMMARY

Buying a domain is a tool call here, so read the scopes.

Checkout is its own grant, separate from searching and from reading your portfolio. Grant search and portfolio read and the assistant can research names all day without ever being able to spend money — which is the setup most people actually want first.

What it is

A remote server at https://api.unstoppabledomains.com/mcp/v1 that puts the Unstoppable Domains User API in front of an assistant: domain search, portfolio, DNS, cart and checkout, marketplace listings and buyer conversations.

What you get

ud_domains_search checks availability and pricing across the TLDs you name; ud_tld_list says which are supported
ud_portfolio_list filters by name, status, registry type, expiry window and length
DNS records and nameservers: add, update, remove, list, and switch between default and custom nameservers
Cart and checkout: add a domain, a listed domain or a renewal, read payment methods, and complete the purchase
Marketplace: create, update and cancel listings, respond to offers, and read leads and buyer messages
Backorders on expiring names, and generated landing pages for domains you are selling

Requirements

An Unstoppable Domains account. OAuth is the recommended path and its grants are separate — domain search, portfolio read, portfolio write, cart read, cart write and checkout. An MCP API key from the Advanced tab of Account Settings is the alternative, sent as a bearer token. Some clients ask you to approve every action; loosening that is a setting, and it means the assistant acts with less confirmation.

Setup effort

One command, then sign in — claude mcp add --transport http unstoppable-domains https://api.unstoppabledomains.com/mcp/v1, then approve the OAuth sign-in

See installation options

Working a portfolio that has outgrown a spreadsheet

Handling an offer that came in overnight

05

Letting an assistant shop without your wallet

Grant search and portfolio read only; leave cart write and checkout ungranted until you decide to buy.
