We're excited to announce the first release of the Testlemon MCP (Model Context Protocol) Server! This powerful integration brings domain validation capabilities directly to your AI workflows, making it easier than ever to check the health and security of your domains through natural language conversations with Claude and other MCP-compatible AI assistants.
What is the Testlemon MCP Server?
The Testlemon MCP Server is a specialized tool that connects Testlemon's domain validation capabilities with AI assistants through the Model Context Protocol. This integration allows you to perform comprehensive domain health checks directly from your AI conversations, eliminating the need to switch between different tools and interfaces.
Built on Anthropic's Model Context Protocol standard, our MCP server enables seamless communication between AI models and Testlemon's testing infrastructure. This means you can now ask your AI assistant to check domain configurations, validate security settings, and monitor domain health—all through natural language commands.
Domain Validation Features
The first version of our MCP server focuses on comprehensive domain validation, checking six critical aspects of your domain's health and security:
- DKIM (DomainKeys Identified Mail): Validates that your domain has proper DKIM records configured for email authentication, helping prevent email spoofing and improving deliverability.
- SPF (Sender Policy Framework): Checks for valid SPF records that specify which mail servers are authorized to send emails on behalf of your domain.
- DMARC (Domain-based Message Authentication, Reporting & Conformance): Verifies DMARC policy configuration to protect your domain from email-based attacks and phishing attempts.
- SSL Certificate: Validates SSL certificate status, expiration dates, and configuration to ensure secure HTTPS connections.
- Domain Expiration: Monitors domain registration expiration dates to prevent unexpected domain lapses that could disrupt your services.
- TLS Configuration: Checks TLS settings and cipher suites to ensure your domain uses secure encryption protocols.
Setting Up Testlemon MCP Server with Claude
Getting started with the Testlemon MCP Server in Claude Desktop is straightforward. Follow these steps to configure the integration:
1. Configure Claude Desktop
Add the following configuration to your Claude Desktop configuration file. On macOS, this is typically located at ~/Library/Application Support/Claude/claude_desktop_config.json:
{
"mcpServers": {
"testlemon": {
"command": "docker",
"args": [
"run",
"-i",
"--rm",
"itbusina/testlemon-mcp:latest"
],
"env": {
}
}
}
}2. Restart Claude Desktop
After saving the configuration file, restart Claude Desktop to load the new MCP server. You should now be able to use domain validation commands directly in your conversations with Claude.
Using the MCP Server
Once configured, you can start using the Testlemon MCP Server by asking Claude to validate domains. Here are some example commands you can try:
- "Please validate the domain example.com using Testlemon"
- "Check the SSL certificate and email security for mywebsite.com"
- "Run a complete domain health check on testlemon.com"
- "Validate DMARC and SPF records for my-business-domain.com"
Claude will use the MCP server to perform the validation and provide you with detailed results, including any issues found and recommendations for improvement.
Benefits of Using Testlemon MCP Server
The Testlemon MCP Server offers several advantages for developers, system administrators, and security professionals:
- Streamlined Workflow: Perform domain validations directly from your AI conversations without switching tools or interfaces.
- Natural Language Interface: Use simple, conversational commands to trigger complex domain validation processes.
- Comprehensive Checks: Get detailed insights into six critical aspects of domain health and security in a single command.
- Instant Results: Receive immediate feedback on domain configurations and security settings.
- Integration Ready: Built on the standard Model Context Protocol, ensuring compatibility with current and future AI assistants.
What's Next?
This first release of the Testlemon MCP Server is just the beginning. We're already working on expanding the capabilities to include:
