Namecheap MCP

Check domain availability across 600+ TLDs without leaving Claude

Stop tab-switching between Claude and Namecheap. Ask Claude to check domains conversationally, get instant results, and continue brainstorming.

You: "I'm building a restaurant menu app. Help me find a domain."

Claude: *checks 20 domains in 2 seconds*
✅ menusaas.com - available ($12.98/year)
✅ restaurantmenu.io - available ($34.98/year)
❌ menu.app - taken
✅ getmenu.ai - available ($89.98/year)

Perfect for: Startup naming sessions · Domain research · Agency client work · Content creation

Why Use This

Before: Brainstorm with Claude → Tab to Namecheap → Type domain → Check → Back to Claude → Repeat 20 times → 30 minutes wasted

After: "Check if these 20 domains are available" → Instant results → Keep brainstorming

Use Cases

Startup Naming

You: "I'm building a SaaS for restaurant menus. Help me brainstorm domains."

Claude: Let me suggest some options and check availability...
✅ menusaas.com
✅ restaurantmenu.io
✅ tablemenu.app
❌ menu.com (taken)
✅ getmenu.co

Want me to check more variations?

Batch Checking

You: Check these domains:
- myapp.com
- myapp.io
- myapp.ai
- myapp.co
- myapp.net
- getmyapp.com
- trymyapp.com
- myapp.app

Claude: *checks all 8 at once*
✅ myapp.io - available
✅ getmyapp.com - available
❌ myapp.com - taken
...

Finding Alternatives

You: "example.com is taken. Find me 10 similar available domains."

Claude: *generates and checks variations*
✅ getexample.com
✅ tryexample.com
✅ example.io
✅ example.app
❌ examples.com (taken)
...

Domain Research

You: "Check if any single-word tech domains are available in .ai"

Claude: *batch checks common tech terms*
✅ compiler.ai - available ($89.98/year)
❌ code.ai - premium domain ($15,000)
✅ deploy.ai - available ($89.98/year)
...

How It Works

Architecture:

Claude MCP → Hosted Backend → Namecheap API → Results

1. You ask Claude to check domains (natural language)
2. Claude calls the Namecheap MCP tool
3. MCP hits the hosted backend (no API keys needed)
4. Backend queries Namecheap API in real-time
5. Results return with availability + pricing + purchase links

Why a hosted backend?

Zero setup. You don't need Namecheap API credentials, IP whitelisting, or configuration. Just install and use.

Response Format

The MCP returns structured results Claude can format for you:

Available Domains:

• Domain name
• Price per year
• Direct purchase link

Taken Domains:

• Domain name
• Availability status

Premium Domains:

• Domain name
• Premium price
• Marketplace link

Coverage

600+ TLDs including:

| Popular | Developer | Regional | Creative | |---------|-----------|----------|----------| | .com | .io | .uk | .xyz | | .net | .dev | .eu | .online | | .org | .ai | .ca | .store | | .co | .app | .de | .tech | | .me | .tech | .fr | .fun |

FAQ

Do I need a Namecheap account?

No — anyone can check availability. You only need a Namecheap account when you're ready to buy.

Is this official?

This is a community tool using Namecheap's public API. Purchase links go directly to Namecheap.com.

What about rate limits?

The hosted backend handles rate limiting. Normal usage (checking dozens of domains per day) won't hit limits.

Can I use my own Namecheap API key?

Yes. Set these env vars instead of BATCHIT_API_URL:

{
  "NAMECHEAP_API_USER": "your_username",
  "NAMECHEAP_API_KEY": "your_api_key",
  "NAMECHEAP_USERNAME": "your_username",
  "NAMECHEAP_CLIENT_IP": "your_ip"
}

Is it secure?

The hosted backend only checks availability — it can't access your Namecheap account or buy domains. Purchases happen directly on Namecheap.com.

What about privacy?

Domain searches are not logged. We don't track what you check.

Advanced Usage

Install from Source

For development or customization:

git clone https://github.com/ziggythebot/namecheap-mcp.git
cd namecheap-mcp
npm install

Then in ~/.claude/settings.json:

{
  "mcpServers": {
    "namecheap": {
      "command": "node",
      "args": ["/absolute/path/to/namecheap-mcp/index.js"],
      "env": {
        "BATCHIT_API_URL": "https://transcripts-scheme-database-yale.trycloudflare.com"
      }
    }
  }
}

Self-Hosted Backend

Want to run your own backend? See DEPLOYMENT_SUMMARY.md

Requirements:

• Namecheap API credentials
• Static IP (for Namecheap whitelist)
• Node.js server

Batch API

Check multiple domains programmatically:

curl -X POST https://transcripts-scheme-database-yale.trycloudflare.com/api/namecheap/check-domains \
  -H "Content-Type: application/json" \
  -d '{"domains": ["example.com", "test.io"]}'
