以下摘录自该仓库的 README(片段) · 在 GitHub 读完整 README →
**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 **up to 92% 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:
**Claude Skill (ClawHub):** clawhub install dsk-available-domains — https://clawhub.ai/johnsmalls22-rgb/skills/dsk-available-domains
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.
