# 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](https://domainsearchking.com/ai-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):**

```bash
claude mcp add --transport http domain-search-king https://domainsearchking.com/api/mcp
```

**Claude Desktop / Cursor / other MCP clients** — add to your MCP config:

```json
{
  "mcpServers": {
    "domain-search-king": { "url": "https://domainsearchking.com/api/mcp" }
  }
}
```

**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.

## 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.
