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:
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
2. Connect to your AI coding tool
Claude Code
Codex CLI
Cursor
Add to .cursor/mcp.json:
Claude Desktop
Add to claude_desktop_config.json:
3. Install the brand-naming skill (optional, Claude Code only)
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:
Claude will automatically check domains as it brainstorms.

How It Works
- 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
Test locally:
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
