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 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 |

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.
