Domain Radar

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

30+ TLDs — including trending ones

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
