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": {
    "namecheap": {
      "command": "npx",
      "args": [
        "-y",
        "@birdmania1/namecheap-mcp"
      ],
      "env": {
        "NAMECHEAP_API_USER": "your-value",
        "NAMECHEAP_API_KEY": "your-value",
        "NAMECHEAP_USERNAME": "your-value",
        "NAMECHEAP_CLIENT_IP": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add namecheap --env NAMECHEAP_API_USER=your-value --env NAMECHEAP_API_KEY=your-value --env NAMECHEAP_USERNAME=your-value --env NAMECHEAP_CLIENT_IP=your-value -- npx -y @birdmania1/namecheap-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "namecheap": {
      "command": "npx",
      "args": [
        "-y",
        "@birdmania1/namecheap-mcp"
      ],
      "env": {
        "NAMECHEAP_API_USER": "your-value",
        "NAMECHEAP_API_KEY": "your-value",
        "NAMECHEAP_USERNAME": "your-value",
        "NAMECHEAP_CLIENT_IP": "your-value"
      }
    }
  }
}

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": {
    "namecheap": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@birdmania1/namecheap-mcp"
      ],
      "env": {
        "NAMECHEAP_API_USER": "your-value",
        "NAMECHEAP_API_KEY": "your-value",
        "NAMECHEAP_USERNAME": "your-value",
        "NAMECHEAP_CLIENT_IP": "your-value"
      }
    }
  }
}

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.

Common questions

Is Namecheap 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?

You need to fill in: NAMECHEAP_API_USER, NAMECHEAP_API_KEY, NAMECHEAP_USERNAME, NAMECHEAP_CLIENT_IP

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 (1.1.3) reached the registry 8 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?

Namecheap MCP

Check domain availability across 600+ TLDs on Namecheap without leaving Claude

Ask Claude to check domains conversationally and get instant results with purchase links.

Installation

npx @birdmania1/namecheap-mcp

⚠️ IMPORTANT: After installing, you MUST configure your Namecheap API credentials (see Setup below). The MCP won't work without them.

Setup (3 minutes)

Copy-paste these commands to Claude one at a time and follow the steps:

Step 1: Get Your IP Address

Say to Claude:

Visit https://api.ipify.org and tell me my IP address

Claude will tell you your IP. Write it down - you'll need it in steps 2 and 3.

Step 2: Enable Namecheap API

Do these steps manually in your browser:

Go to https://www.namecheap.com and log in
Click Profile (top right) → Tools → Namecheap API Access
Click "Enable API Access"
Under Whitelisted IPs, click "Add New" and paste your IP from Step 1
Copy your API key - you'll need it in Step 3

Step 3: Configure Claude Code

Say to Claude:

Add the Namecheap MCP server to my Claude Code config with these credentials:

API User: [your namecheap username]
API Key: [the key you just copied]
Username: [your namecheap username]
Client IP: [the IP from step 1]

Use this exact MCP server config:

{ "command": "npx", "args": ["-y", "@birdmania1/namecheap-mcp"], "env": { "NAMECHEAP_API_USER": "your_username", "NAMECHEAP_API_KEY": "your_api_key_here", "NAMECHEAP_USERNAME": "your_username", "NAMECHEAP_CLIENT_IP": "your.ip.address.here" } }

Important:

Add it to the SAME config file where your other MCP servers are (check where perplexity/github/etc are configured)
Make sure "namecheap" only appears in ONE config file (not duplicated across ~/.claude.json, settings.json, or mcp.json)
If you get errors, check for duplicate entries and remove them

Important: Replace the placeholder values with your actual credentials before sending to Claude.

Step 4: Restart Claude Code

Fully quit Claude Code (⌘+Q on Mac, Alt+F4 on Windows) and reopen it.

Step 5: Test It

Say to Claude:

Check if example.com and startup.io are available

You should get instant results with prices and purchase links!

If it doesn't work, see Troubleshooting below.

What You Can Do

Find startup names:

"I'm building a SaaS for restaurants. Help me find a domain."

Check specific domains:

"Check if myapp.com, myapp.io, and myapp.ai are available"

Find alternatives:

"example.com is taken. Find me similar domains."

Research TLDs:

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

Features

600+ TLDs — .com, .io, .ai, .xyz, .tech, and more
Batch checking — Check 100 domains at once
Instant pricing — See costs upfront
Purchase links — One-click to buy
Secure — Direct API, no proxy server

Troubleshooting

"Invalid request IP" error:

Your IP changed. Update it in Namecheap's whitelist.
Ask Claude "What's my IP?" to get your current IP.

"API access not enabled":

Enable it in your Namecheap account settings.

Not showing up in Claude:

Check for duplicate entries: "namecheap" should only appear in ONE config file
Common locations: ~/.claude.json, ~/.claude/settings.json, ~/.claude/mcp.json
Remove duplicates, keeping only the one in the file where your other MCPs live
Restart Claude Code after editing (full quit and reopen)
Verify JSON is valid (no trailing commas, proper nesting)
