Getting Started with LambdaTest MCP Server

LambdaTest MCP Server is all-in-one MCP server that dramatically simplifies and accelerates your automated testing workflow. By leveraging the Model Context Protocol (MCP), it enables seamless integration between AI assistants and your testing environment, reducing setup time from hours to minutes.

What is Model Context Protocol (MCP)?

The Model Context Protocol (MCP) acts like a "USB-C for AI integrations," creating a universal language between AI models and applications. This standardized interface allows AI assistants to connect with diverse software tools, making it significantly easier to expand capabilities across your digital workflow.

Key Benefits of LambdaTest MCP Server

Here are the key benefits of using LambdaTest MCP Server:

• Automated Setup: Reduce configuration time from hours to seconds
• Smart Analysis: Automatically identify project types, frameworks, and test structures
• Dynamic Commands: Generate precise test commands tailored to your project
• Auto-Configuration: Create accurate YAML configuration files without manual intervention
• Real-Time Monitoring: Track test executions with immediate updates
• Efficient Debugging: Inspect test results with comprehensive recordings
• Instant Documentation: Access relevant documentation through integrated AI agents

Connecting to LambdaTest MCP Server

Connecting with Cline

Cline (The Collaborative AI Coder) is an advanced AI-powered coding assistant that integrates directly into your development workflow. It provides intelligent code suggestions and documentation assistance, and now, with MCP support, you can interface with external tools like HyperExecute to enhance your testing capabilities. Cline offers natural language interactions with your codebase, allowing you to simply describe what you need rather than manually configuring everything.

Installing Cline in VS Code:

Step 1: Open VS Code.
Step 2: Click on the Extensions icon in the Activity Bar on the side of the window (or press Ctrl+Shift+X).
Step 3: Search for Cline in the Extensions Marketplace.

Step 4: Click Install on the Cline – The Collaborative AI Coder extension.
Step 5: Once installed, you'll see the Cline icon in your VS Code sidebar.
Step 6: Click on the Cline icon to open the Cline panel.

Connecting Cline to LambdaTest MCP Server

VS Code Configuration:

Step 1: In VS Code, click on the Cline icon in the sidebar to open the Cline panel.
Step 2: Under the MCP Servers section, click Remote Servers.

Step 3: Add Server Name as MCP-LambdaTest.
Step 4: Enter the following server configiration and save it: http://mcp.lambdatest.com/mcp
Step 5: Click on Authenticate and you will be redirected to lambdatest.com for authentication.

Step 6: Provide valid credentials and authorise client to use LambdaTest MCP server.

Step 7: Post authorisation, launch your IDE.

Step 8: MCP Lambdatest should be connected successfully.

Interacting with LambdaTest MCP Server

Once connected, you can start using Cline to interact with the LambdaTest MCP Server. A common workflow would be:

Step 1: Open your project in VS Code.
Step 2: Open the Cline panel.
Step 3: Type the following prompt: Analyze the project and create a LambdaTest YAML file using MCP LambdaTest server.
Step 4: Cline will:

• analyze your project structure.
• Identify your testing framework and test files.
• Generate appropriate test runner commands.
• Create a complete LambdaTest YAML configuration file tailored to your project.
• Save the YAML file to your project directory.
  

Step 5: You can then review the generated YAML file and make any necessary adjustments (if any, e.g., adding environment variables, etc.) before running your tests on the LambdaTest MCP Platform.

You can also ask Cline for more specific operations, such as:

• "What are the key features of LambdaTest?"
• "What does failFast in HyperExecute mean?"

The natural language interface allows you to work with HyperExecute without having to remember specific command syntax or configuration details.

Connecting With Other MCP-Compatible Tools

For any other MCP-compatible tool, use the following URL format:

https://mcp.lambdatest.com/mcp

In your MCP tool, use the following configuration file:

{
  "mcpServers": {
    "mcp-lambdatest": {
      "disabled": false,
      "timeout": 60,
      "type": "stdio",
      "command": "npx",
      "args": [
        "mcp-remote@latest",
        "https://mcp.lambdatest.com/mcp",
      ]
    }
  }
}
