mcp-domain-radar

Works with
Claude Code · Claude Desktop · Cursor · Codex CLI · any MCP-compatible client

MCP server that checks domain availability in real-time during brand naming.

Name your brand. Check the domain. All in one conversation.

Why?

We've all been there:

You:    "Suggest a name for my service"
AI:     "How about NexFlow?"
You:     Search nexflow.com... already taken
You:    "Another one"
AI:     "DataPulse?"
You:     Search datapulse.com... also taken
You:    "..."
        (repeat 10 times)

Install mcp-domain-radar once, and your AI checks domain availability the moment it thinks of a name. No more switching between browser and terminal.

Quick Start

1. Install

npm install -g mcp-domain-radar

2. Connect to your AI coding tool

Claude Code

claude mcp add domain-radar -- mcp-domain-radar

Codex CLI

codex mcp add domain-radar -- npx mcp-domain-radar

Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "domain-radar": {
      "command": "npx",
      "args": ["mcp-domain-radar"]
    }
  }
}

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "domain-radar": {
      "command": "npx",
      "args": ["mcp-domain-radar"]
    }
  }
}

3. Install the brand-naming skill (optional, Claude Code only)

mkdir -p ~/.claude/skills/brand-naming
cp node_modules/mcp-domain-radar/.claude/skills/brand-naming/SKILL.md ~/.claude/skills/brand-naming/

Or copy it manually from the GitHub repo.

4. Use it

With the skill installed, type /brand-naming in Claude Code to start a guided naming session.

Or just talk naturally:

"I'm building a task management app for developers.
 Help me find a brand name with an available domain."

Claude will automatically check domains as it brainstorms.

What You Get

4 Tools — automatically used by Claude during conversations

Tool	What it does
`check_domains`	Check exact domain names — `"Is mybrand.com taken?"`
`check_brand_domains`	Check one name across 17+ TLDs at once — `"Check nexflow across all popular TLDs"`
`suggest_and_check_domains`	Generate name variations from keywords & check all — `"Brainstorm names from keywords: pulse, data, flow"`
`list_supported_tlds`	Show all TLDs this server supports

30+ TLDs — including trending ones

Category	TLDs
Classic	`.com` `.net` `.org`
Tech / Startup	`.io` `.dev` `.app` `.co` `.tech` `.sh`
Trending	`.ai` `.gg` `.so` `.me` `.xyz` `.cc` `.to` `.run` `.cloud` `.tv`
Creative	`.lol` `.wtf` `.cool` `.world` `.studio` `.design`
Commerce	`.online` `.site` `.store`
Country	`.kr`

Examples

Check a specific name

You: Check if "nexflow" is available — try .com, .io, .ai, and .dev

AVAILABLE:
  + nexflow.dev
  + nexflow.ai

TAKEN:
  - nexflow.com
  - nexflow.io
