Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

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

Run this in your terminal

claude mcp add domain-radar -- npx -y mcp-domain-radar

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

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

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "domain-radar": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "mcp-domain-radar"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Domain Radar safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.2) reached the registry 7 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

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"] } } }

</details>

Claude Desktop

Add to claude_desktop_config.json:

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

</details>

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

--- 2 available / 2 taken / 0 unknown ---

Brainstorm from keywords

You: I need a name for an AI code review tool.

Keywords: code, review, pulse, scan. Find me names with available domains.

```

Generated 20 name variations from: code, review, pulse, scan Checking .com .io .ai .dev .app .co for each

codepulse (compound) — available: .dev, .ai | taken: .com, .io
scanflow (suffix) — available: .ai, .dev, .app | taken: .com
getpulse (prefix) — available: .dev, .co | taken: .com, .io, .ai
revscan (blend) — available: .com, .io, .ai, .dev, .app, .co
codelab (suffix) — all checked TLDs taken

TOP PICKS (have available domains): revscan → revscan.com, revscan.io, revscan.ai, revscan.dev, revscan.app, revscan.co codepulse → codepulse.dev, codepulse.ai scanflow → scanflow.ai, scanflow.dev, scanflow.app

Guided workflow with the `brand-naming` prompt

The server includes a built-in prompt template that walks you through the full naming process step by step.

How It Works

Your question

│ ▼ Claude brainstorms names │ ▼ mcp-domain-radar ├── 1. DNS lookup (fast — if it resolves, it's taken) └── 2. WHOIS query (definitive — checks registration status) │ ▼ Only names with available domains are recommended

No API keys required — uses native DNS and WHOIS protocols
Rate-limit friendly — batches queries with delays
Works offline for DNS checks — WHOIS requires network

Development

git clone https://github.com/sonwr/mcp-domain-radar.git

cd mcp-domain-radar npm install npm run build

Test locally:

claude mcp add domain-radar -- node ./dist/index.js

Roadmap

Domain price estimation per registrar
Expiring / recently dropped domain suggestions
Registrar API integration (Namecheap, Cloudflare, GoDaddy)
Internationalized domain name (IDN) support
More TLDs and WHOIS servers
