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.

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
