Domain Checker MCP Server

Provides domain availability and suggestion services with batch and multi-TLD support for automated MCP workflows.

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "3viky-mcp-domain-checker": {
      "command": "node",
      "args": [
        "/path/to/mcp-domain-checker/dist/index.js"
      ]
    }
  }
}

You have a Domain Checker MCP Server at your disposal to quickly verify if domain names are available and to generate intelligent domain suggestions. It integrates with MCP clients to perform single and batch lookups across multiple TLDs, helping you build domain-related features, automate registrations, or run research on domain availability.

How to use

You connect to the Domain Checker MCP Server from your MCP client and call its tools to check availability or generate suggestions. Use it to verify a single domain, batch-check several domains at once, or request smart domain name recommendations based on your keywords. You can target multiple TLDs to explore a broader set of options.

How to install

Prerequisites: you need Node.js and npm installed on your system.

Install dependencies and build the server in your project workspace.

Configuration

No separate configuration is required by default for the server. It uses public WHOIS services to perform domain checks.

{
  "mcpServers": {
    "domain_checker": {
      "command": "node",
      "args": ["/path/to/mcp-domain-checker/dist/index.js"]
    }
  }
}

Usage examples

Check a single domain for availability in your client.

await check_domain({ domain: "example.com" })

Check multiple domains in a batch to save time.

await check_domains_batch({
  domains: ["myapp.com", "myapp.io", "myapp.dev"]
})

Generate domain name suggestions from keywords for multiple TLDs.

await suggest_domains({
  keywords: ["tech", "startup", "ai"],
  count: 10,
  tlds: ["com", "io", "ai", "dev"]
})

Development

For local development, you can run a watch mode, build for production, and perform type checks.

npm run dev

npm run build

tsc --noEmit
