Domain Search King — MCP Server for Available Domain Name Search
Find domain names that are actually available to register — verified live against the Verisign RDAP registry, not AI guesses.
Remote MCP (Model Context Protocol) server for Claude, Claude Code, Cursor, VS Code, Windsurf, and any MCP-compatible AI agent. Ask your AI for business name ideas and get back only .com domains that are available right now.
- Endpoint:
https://domainsearchking.com/api/mcp(remote HTTP, JSON-RPC 2.0 — no install, no API key) - Product page + one-click install: https://domainsearchking.com/mcp
Why this exists: AI models hallucinate domain availability
LLMs confidently suggest domain names that were registered decades ago. Our AI Domain Hallucination Index found ~89% of AI-suggested domains are already taken.
Real examples — names AI models routinely call "available":
| Domain AI suggested | Reality (RDAP registry record) |
|---|---|
| dailygrind.com | Registered since 1995 |
| morningritual.com | Registered since 2004 |
Domain Search King checks every name against the live registry before your agent ever sees it. Verified-available examples returned at time of writing: lunaroast.com, brewotic.com, duskern.com, mochanox.com.
Tools
| Tool | What it does |
|---|---|
find_available_domains(keyword, description, count) | Generates brandable .com names for your business idea, returns ONLY ones currently available to register |
find_available_domains_by_pattern | Pattern-based domain search (starts-with / contains / ends-with), availability-verified |
check_domain(domain) | Live availability check for a single domain, straight from the registry |
Install
Claude Code (CLI):
Claude Desktop / Cursor / other MCP clients — add to your MCP config:

Per-client setup tabs (VS Code, Windsurf, and more) + an in-page inspector: https://domainsearchking.com/mcp
How it works
Every candidate name is checked live against the authoritative Verisign RDAP registry at query time. No cached lists, no WHOIS scraping, no guessing. If the tool returns a name, it was available at the moment you asked.

FAQ
Is it free? Yes — the MCP server and the site tools are free to use.
Why only names that are available? Because a name idea you can't register is worthless. Other generators give ideas; Domain Search King gives you names you can actually buy right now.
What's RDAP? The registry's official successor to WHOIS — structured, authoritative registration data straight from Verisign. It's how we verify availability live instead of guessing.
