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.
| 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.
