This MCP server enables Claude and other AI assistants to generate personalized coding challenges from FrontendLeap. It provides secure API-key authentication, multi-language challenge support, and instant challenge creation by saving content directly to your platform.

How to use

You run this MCP server locally or on your infrastructure and connect it to an MCP client such as Claude Desktop. Once running, you can request Claude-generated challenges that include explanations, starter code, and tests. Use the provided configuration to connect your client, then leverage the available tool to create complete challenges tailored to your learners.

To connect Claude Desktop, configure the frontendleap MCP entry so the client launches the server process and passes the required environment variables. The MCP server runs as a local process and communicates through the standard input/output interface.

Example configuration for Claude Desktop to start the MCP server as a local process:

{
  "mcpServers": {
    "frontendleap": {
      "command": "node",
      "args": ["/path/to/frontendleap-mcp-server/dist/index.js"],
      "env": {
        "FRONTENDLEAP_API_KEY": "YOUR_API_KEY",
        "FRONTENDLEAP_API_URL": "https://fl.test"
      }
    }
  }
}

How to install

Prerequisites: ensure Node.js and npm are installed on your system.

Install dependencies

npm install

Configure environment variables

Copy the example environment file and edit it to include your API key.

cp .env.example .env
# Edit .env and add your FRONTENDLEAP_API_KEY

Build the server

npm run build

Start the server

npm start

Notes and tips

The server uses API-key authentication and supports JavaScript, TypeScript, HTML, and CSS challenges. You can create complete Claude-generated challenges with explanations, starter code, and tests using the create_challenge workflow.

Security and usage considerations

Keep your FRONTENDLEAP_API_KEY secure. Store it in a protected environment and rotate it if you suspect it has been compromised.

Available tools

create_challenge

Create a complete coding challenge with Claude-generated content, including title, description, explanation, starter_code, test_code, optional solution, language, and difficulty.
