Domain Search King MCP Server

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 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.

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.
