Create project await createProject({ name: "my-app", type: "full-stack", path: "/projects", features: ["typescript", "database", "auth", "docker"] }); // 2. Setup backend await createApiEndpoint({ name: "Product", framework: "express", methods: ["GET", "POST", "PUT", "DELETE"], authentication: true, validation: true, projectPath: "/projects/my-app/backend" }); // 3. Setup authentication await setupAuthentication({ type: "jwt", framework: "express", projectPath: "/projects/my-app/backend", features: ["registration", "login", "logout", "password-reset"] }); // 4. Create middleware await createMiddleware({ name: "rateLimiter", framework: "express", type: "rate-limit", projectPath: "/projects/my-app/backend", config: { windowMs: 900000, max: 100 } }); // 5. Setup WebSockets await setupWebsockets({ framework: "express", library: "socket.io", projectPath: "/projects/my-app/backend", features: ["chat", "notifications"] }); // 6. Create background jobs await createBackgroundJob({ name: "emailQueue", framework: "express", queueType: "bull", projectPath: "/projects/my-app/backend", jobType: "email" }); // 7. Dockerize application await createDockerfile({ framework: "node", projectPath: "/projects/my-app/backend", port: 3000 }); await createDockerCompose({ projectPath: "/projects/my-app", services: [ { name: "backend", type: "app", port: 3000 }, { name: "postgres", type: "database" }, { name: "redis", type: "cache" } ] }); // 8. Setup deployment await deployToCloud({ provider: "vercel", projectPath: "/projects/my-app/frontend", appName: "my-app-frontend" }); await setupSsl({ provider: "letsencrypt", domain: "myapp.com", projectPath: "/projects/my-app", email: "admin@myapp.com" }); await setupLoadBalancer({ type: "nginx", projectPath: "/projects/my-app", backends: [ { host: "localhost", port: 3001, weight: 1 }, { host: "localhost", port: 3002, weight: 1 } ], ssl: true }); ``` ## Configuration ### Environment Variables ```bash # Security JWT_SECRET=your-jwt-secret SESSION_SECRET=your-session-secret CONFIG_ENCRYPTION_KEY=32-character-hex-key # Resource Limits MAX_FILE_SIZE=10485760 # 10MB MAX_MEMORY_MB=512 # 512MB COMMAND_TIMEOUT_MS=30000 # 30 seconds # Paths WORKSPACE_ROOT=/Users/your-username/mcp-workspace LOG_DIR=./logs TEMP_DIR=./temp ``` ## Architecture Improvements ### Base Tool Classes - **`BaseTool`**: Foundation for all tools with validation, error handling, and logging - **`FileBasedTool`**: Specialized for file operations with size checks and backups - **`DatabaseTool`**: Specialized for database operations with connection pooling ### Utility Classes - **`Logger`**: Structured logging with context and metrics - **`ErrorHandler`**: Comprehensive error handling with retry logic - **`ResourceManager`**: Tracks and cleans up all resources - **`SecurityManager`**: Handles path sanitization and secure execution - **`RateLimiter`**: Prevents abuse with configurable limits ## Performance Optimizations 1. **Connection Pooling**: Reuse database connections 2. **Resource Limits**: Prevent memory exhaustion 3. **Timeout Management**: Prevent hanging operations 4. **Circuit Breakers**: Fail fast for unreliable operations 5. **Rate Limiting**: Prevent abuse and overload ## Security Enhancements 1. **Input Validation**: All inputs validated with Zod schemas 2. **Path Sanitization**: Prevent directory traversal attacks 3. **Command Sanitization**: Prevent command injection 4. **Encryption**: Sensitive configuration encrypted 5. **Rate Limiting**: Prevent brute force and DoS attacks ## Next Steps ### Potential Enhancements 1. Add more cloud providers (DigitalOcean, Linode) 2. Add more testing frameworks (Cypress, Playwright) 3. Add GraphQL support 4. Add microservices templates 5. Add Kubernetes deployment tools 6. Add more AI integrations 7. Add database migration rollback 8. Add blue-green deployment support ### Contributing To add new tools: 1. Create a new tool class extending `BaseTool` 2. Add proper validation schema 3. Implement the `executeInternal` method 4. Add to the appropriate tool collection 5. Update documentation and tests ## Conclusion The MCP Software Engineer server is now a fully functional, secure, and powerful tool for full-stack development. With 49 comprehensive tools covering all aspects of modern software development, it can handle everything from project creation to deployment and monitoring.
