Whodis MCP Server: Enhancing Domain Availability Checks for AI Applications

Overview: What is Whodis MCP Server?

Whodis MCP Server is an advanced infrastructure solution designed to facilitate secure and efficient domain availability checks through Model Context Protocol (MCP). Built specifically to integrate seamlessly with various AI applications, this server provides critical functionality by leveraging WHOIS lookups to determine if desired domain names are available for registration. By implementing the MCP standard, it ensures flexible and versatile connectivity across a broad spectrum of AI tools and data sources.

🔧 Core Features & MCP Capabilities

Whodis MCP Server offers several key features that make it an indispensable tool for developers working on AI applications:

• Domain Availability Checks: Utilizes the whoiser library to perform WHOIS lookups, providing real-time insights into whether a given domain name is available.
• MCP Tool Integration: Exposes the check-domain-availability tool, allowing MCP clients (such as Claude Desktop, Continue, Cursor) to integrate seamlessly with the server.
• Command-Line Interface (CLI): Offers a CLI interface for direct usage and testing, enhancing flexibility and convenience.
• Structured Logging: Implements detailed logging mechanisms for debugging and monitoring purposes.
• Configurable Environment Variables: Supports configuration through environment variables or .env files, enabling easy tailoring to specific needs.

These features collectively contribute to making Whodis MCP Server a powerful tool in the domain of AI application development and integration.

⚙️ MCP Architecture & Protocol Implementation

The architecture of Whodis MCP Server is designed with modularity and scalability in mind. Key components include:

• src/cli: Houses the command-line interface logic, providing an easy entry point for developers to interact directly with the server.
• src/controllers: Contains business logic related to domain checks, ensuring efficient processing of requests.
• src/services: Facilitates interaction with the whoiser library to perform WHOIS lookups and manage domain state.
• src/tools: Defines MCP tools and validates arguments, crucial for maintaining consistency across tool usage.
• src/types: Includes shared type definitions, enhancing maintainability and readability of code.
• src/utils: Provides utility functions used throughout the application, such as logging and error handling.

This layered architecture ensures that each part of the system can be developed, tested, and maintained independently while working cohesively together. The seamless integration with MCP clients is further underpinned by a robust protocol implementation and data flow.

🚀 Getting Started with Installation

Getting started with Whodis MCP Server involves several straightforward steps:

1. Prerequisites:

   • Node.js (>=18.x): Download from Node.js official website.
   • Git: For version control, which can be obtained from Git官方网站.

2. Clone and Install:

# Clone the repository
git clone https://github.com/vinsidious/whodis-mcp-server.git
cd whodis-mcp-server

# Install dependencies
npm install

3. Run Development Server: Start the server in development mode to interact with it via the MCP Inspector:

npm run dev:server

This command starts the MCP server and enables the MCP Inspector at http://localhost:5173, allowing you to test the check-domain-availability tool.

4. Test the Tool via CLI: Run the domain availability checker directly from the command line:

# Using CLI in development mode
npm run dev:cli -- check-domain-availability example.com non-existent-domain-12345.org

# Or run the built version
npm run start:cli -- check-domain-availability google.com my-unique-idea.dev

The output will be a JSON object containing available and unavailable arrays.

💡 Key Use Cases in AI Workflows

Whodis MCP Server is particularly useful for integrating domain availability checks into broader AI workflows. Here are some practical scenarios:

1. Real-time Domain Availability: Instantly determine the availability of new domain names during the ideation phase, ensuring that developers can quickly identify and register suitable options.
2. Automated Registration Pipelines: Combine WHOIS lookups with other automated processes to streamline the registration pipeline, reducing manual intervention and increasing efficiency.

These use cases highlight the value Whodis MCP Server brings to AI development workflows by providing reliable and timely information.

🔌 Integration with MCP Clients

Whodis MCP Server is compatible with various MCP clients, including widely recognized tools in the field:

• Claude Desktop: Fully supported, enabling real-time domain availability checks directly within the application.
• Continue: Integrates seamlessly, allowing developers to leverage the server for quick and accurate domain validation.
• Cursor: Supported but limited to tool integration, meaning specific functionalities may not be available without active development.

By integrating with these MCP clients, Whodis MCP Server ensures a cohesive user experience across different platforms and tools.

📊 Performance & Compatibility Matrix

To ensure optimal performance and compatibility, the Whodis MCP Server has been tested against various MCP clients. Below is a compatibility matrix for reference:

MCP Client	Resources	Tools	Prompts	Status

Continue	Full Support	Full Support	Full Support	✅ Full Support
Cursor	Tools Only	Full Support	Limited	❌ Not Compatible

This matrix helps users understand the current state of integration and enables them to plan their development accordingly.

🛠️ Advanced Configuration & Security

Whodis MCP Server can be configured through both environment variables or .env files. For detailed configuration, refer to the following snippet:

{
  "mcpServers": {
    "[server-name]": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-[name]"],
      "env": {
        "API_KEY": "your-api-key"
      }
    }
  }
}

Additionally, the server includes structured logging for debugging and monitoring. Debug logs can be enabled by setting DEBUG=true:

# Set environment variable
DEBUG=true npm run dev:server

# Or set DEBUG=true in your .env file

Logs are saved to files in ~/.mcp/data/whodis-mcp-server.*.log.

❓ Frequently Asked Questions (FAQ)

Q1: How does the WHOIS lookup process work in Whodis MCP Server?
