Atom.com — Premium Domains MCP Server

An MCP server that lets AI agents search, appraise, trademark-screen, and buy premium brandable domain names from Atom.com — a curated premium domain marketplace and accredited domain registrar.

Remote endpoint: https://mcp.atom.com/mcp (Streamable HTTP)

Domain search works anonymously — no account or API key needed to try it. Account-linked tools use OAuth: your agent opens an Atom.com login page, you approve, done. No client IDs or secrets to configure.

What it's for

Naming a startup, product, or company — get real, buyable names (with actual buy-now prices), not just ideas.
Checking a specific domain — available, taken, or premium-listed, with curated alternatives when it's taken.
Valuing a domain — appraisal with reasoning and comparable sales.
Screening trademarks — a preliminary conflict screen against public USPTO records before you fall in love with a name.
Buying — hand off a pre-filled Atom.com checkout link to complete the purchase on Atom.com.

Tools

Tool	Auth	Description
`search_brandable_domains`	none	Search Atom.com's curated marketplace of premium, brandable domains by concept, industry, or style. Every result is a real listing with a buy-now price.
`check_domain_availability`	Atom.com login	Check whether a specific domain is available, taken, or a premium listing; suggests curated alternatives when taken.
`generate_domain_names`	Atom.com login	Invent new brandable name candidates for a concept, grounded against live availability and Atom.com inventory — every result is actually obtainable.
`appraise_domain`	Atom.com login	Estimate the market value of a domain with reasoning and comparable sales. Always an estimate, not an offer.
`get_domain_details`	Atom.com login	Full detail record for a single Atom.com listing — the deep-dive after picking a name.
`screen_trademark_conflicts`	Atom.com login	Preliminary trademark-conflict screen against public USPTO records. Not legal advice.
`get_checkout_link`	Atom.com login	Pre-filled, authenticated Atom.com checkout URL so the user can complete payment on Atom.com. Charges nothing by itself.

All tools are read-only (readOnlyHint: true) — nothing on this surface spends money or mutates account state. Purchases always complete on Atom.com's own checkout.

When a tool needs authentication the client will open Atom.com's OAuth consent page — log in with (or create) your Atom.com account and approve. Dynamic client registration is supported, so no manual app setup is required.
