Model Context Protocol Server

Give your AI domains that are
actually available

Every other AI suggests names that are already taken. Domain Search King's MCP returns only .com domains verified available to register — live, inside Claude, Cursor, ChatGPT, or any agent.

Why your AI needs this

A language model guesses plausible names — it was never connected to the registry, so most of what it calls "available" is already owned. This MCP checks every candidate against the live .com registry before returning it, so your agent only ever proposes names you can actually register.

✅ Verified, not guessed

Each name is checked against the authoritative registry in real time. Taken names never come back.

Any agent (LangChain · CrewAI · custom)

Point your MCP client at https://domainsearchking.com/api/mcp (JSON-RPC 2.0, streamable HTTP). Call tools/list to discover, then find_available_domains.

What it looks like

Exhaustively list every available domain matching a pattern, across TLDs — and act on names that are verified registrable, not guessed:

You: "Show me every available .com and .net starting with bear or bigbear."
AI (using Domain Search King): Checked 228 combinations live. 36 available — e.g. beargenie.com, and on .net: bearapp.net, bearhq.net, bearkit.net, bearbase.net, bearpro.net, bearcentral.net, bearhero.net, bearflow.net… Every one verified registrable right now.

Or the classic brandable mode:

You: "I'm starting a specialty coffee roaster — find me 5 available .com domains."
AI (using Domain Search King): 5 verified-available .coms: emberroast.com, craftpour.com, slowbrewlab.com, thirdwavebean.com, roastandco.com — no dead ends.

Two tools

find_available_domains_by_pattern(   // ← the differentiator
  keyword:   string   // "bear"  or  "bear, bigbear"
  position:  "starts" | "ends" | "contains" | "all"
  tlds:      ["com","net"]   // also org/io/co/info
  limit:     integer
)
→ EVERY available domain matching the pattern, across TLDs, verified live.

find_available_domains(
  keyword:     string   // e.g. "coffee"
  description: string   // shapes AI-brandable names
  count:       integer
)
→ AI-brandable .coms, verified available.

Frequently asked questions

What is the Domain Search King MCP?

A remote Model Context Protocol server that gives any AI assistant the ability to find .com domains that are actually available to register — verified live against the registry, not guessed by the model.

How is this different from asking ChatGPT or Claude directly?

Raw LLMs invent plausible names but have no idea what's taken — our benchmark found only 5–42% of their "available" suggestions are actually free. This MCP verifies every name first, so 98.7% of what it returns is registrable. See the study.

Which AI tools support it?

Claude (Desktop and Code), Cursor, Windsurf, Continue, ChatGPT (via connectors), and any client that speaks the Model Context Protocol.

Is it free?

Yes — the MCP is free to use. No API key or signup required.

Do I need an API key?

No. Just add the connector URL https://domainsearchking.com/api/mcp and your agent can call it immediately.

How does it check availability?

Every candidate is verified against the authoritative .com registry in real time before it's returned. If a name is taken, it never reaches your agent.

What does it return — just names, or availability too?

It returns .com domains that are already verified available, so the answer is the names you can register. No separate availability step needed.

Can it match my business, not just a keyword?

Yes — pass a description and the names are shaped to fit your business, then filtered to only the available ones.

Does it support other TLDs besides .com?

Today it focuses on .com (the highest-trust extension). Multi-TLD is on the roadmap.

Are there rate limits?

There are fair-use limits to keep it fast and free for everyone. High-volume / commercial access is available — get in touch.

Is my search private?

Yes. Queries are used only to return results; we don't forward your searches to a registrar to front-run them.

Why does my AI agent need this?

Because naming is the one task where a confident wrong answer wastes the most time — registering a name only to find it's taken. This gives your agent ground truth so every name it proposes is real.

Can I use it in a product or my own agent?

Yes. Point any MCP client at the connector URL. For embedded / high-volume use, reach out about commercial access.
