# The "S" in MCP Stands for Security Welcome to the Laravel MCP (Model Context Protocol) Security Workshop! This hands-on workshop will teach you how to build secure MCP servers using Laravel while implementing proper security measures. ## Workshop Overview In this workshop, you'll learn how to: - Set up MCP servers in Laravel - Implement security best practices for MCP servers - Create secure MCP tools - Handle input validation and error handling ## Prerequisites Before starting this workshop, ensure you have: - PHP 8.1 or higher - Composer installed - A fresh Laravel application - Basic knowledge of Laravel concepts ## Getting Started ### Step 1: Install Laravel MCP Package First, install the Laravel MCP package using Composer: ```bash composer require laravel/mcp ``` This package provides the necessary tools and components to build MCP servers within your Laravel application. ### Step 2: Create an MCP Server Generate a new MCP server using the Artisan command: ```bash php artisan make:mcp-server Cde ``` This will create a new server class in `app/Mcp/Servers/CdeServer.php`. The server will handle MCP protocol communication and serve as the main entry point for your MCP tools. ### Step 3: Register the Server Once you've created a server, you must register it in your routes/ai.php file to make it accessible. Laravel MCP provides two methods for registering servers: web for HTTP-accessible servers and local for command-line servers. ```php use App\Mcp\Servers\CdeServer; use Laravel\Mcp\Facades\Mcp; Mcp::local('cde', CdeServer::class); ``` ### Step 4: Create a MCP Tool Generate a new MCP tool that will be used by your server: ```bash php artisan make:mcp-tool FeedDetailTool ``` This creates a tool class in `app/Mcp/Tools/FeedDetailTool.php` that can be attached to your MCP server to provide specific functionality. ## Security Best Practices Covered During this workshop, we'll implement several security measures: ### 1. Input Validation - Validate all incoming MCP requests - Sanitize user inputs to prevent injection attacks - Implement proper data type checking ### 2. Error Handling - Prevent information leakage through error messages - Implement proper logging for security events - Handle edge cases gracefully ### 3. Monitoring & Logging - Log all MCP interactions for audit purposes - Set up alerts for suspicious activity - Monitor performance metrics ### Environment Variables Add the following to your `.env` file: ```env CDE_API_TOKEN=your-api-token ``` ## Testing Your Implementation After completing the setup, test your MCP server: 1. Start the MCP inspector for your CDE server: ```bash php artisan mcp:inspector cde ``` 2. Test the MCP server using an MCP client or the Laravel MCP testing tools: ```bash php artisan mcp:test CdeServer ``` ## Troubleshooting Common issues and solutions: - **Tool not found**: Verify the tool is properly registered with the server - **Server not responding**: Verify the MCP server is properly registered - **Input validation errors**: Ensure all inputs meet the expected format ## Resources - [Laravel MCP Documentation](https://laravel.com/docs/mcp) - [MCP Protocol Specification](https://spec.modelcontextprotocol.io/) - [Laravel Security Best Practices](https://laravel.com/docs/security) ## Workshop Completion By the end of this workshop, you'll have: - A fully functional MCP server with security measures - Understanding of Laravel MCP security best practices - Tools to implement and monitor secure MCP servers - Knowledge to extend your implementation with additional security features Remember: The "S" in MCP stands for Security - never compromise on it! --- **Happy coding and stay secure!** 🔒
