+A standardized protocol for AI assistants to interact with Home Assistant, providing a secure, typed, and extensible interface for controlling smart home devices.
 
 ## Overview
 
-The MCP Server bridges Home Assistant with advanced LLM integrations to deliver intuitive control, automation, and state monitoring. Leveraging a high-performance runtime and real-time communication protocols, MCP offers a seamless experience for managing your smart home.
+The Model Context Protocol (MCP) server acts as a bridge between AI models (like Claude, GPT, etc.) and Home Assistant, enabling AI assistants to:
 
-## Key Features
+- Execute commands on Home Assistant devices
+- Retrieve information about the smart home
+- Stream responses for long-running operations
+- Validate parameters and inputs
+- Provide consistent error handling
 
-### Device Control & Monitoring
-- **Smart Device Control:** Manage lights, climate, covers, switches, sensors, media players, fans, locks, vacuums, and cameras using natural language commands.
-- **Real-time Updates:** Receive instant notifications and updates via Server-Sent Events (SSE).
+## Features
 
-### System & Automation Management
-- **Automation Engine:** Create, modify, and trigger custom automation rules with ease.
-- **Add-on & Package Management:** Integrates with HACS for deploying custom integrations, themes, scripts, and applications.
-- **Robust System Management:** Features advanced state monitoring, error handling, and security safeguards.
+- **Modular Architecture** - Clean separation between transport, middleware, and tools
+- **Typed Interface** - Fully TypeScript typed for better developer experience
+- **Multiple Transports**:
+  - **Standard I/O** (stdin/stdout) for CLI integration
+  - **HTTP/REST API** with Server-Sent Events support for streaming
+- **Middleware System** - Validation, logging, timeout, and error handling
+- **Built-in Tools**:
+  - Light control (brightness, color, etc.)
+  - Climate control (thermostats, HVAC)
+  - More to come...
+- **Extensible Plugin System** - Easily add new tools and capabilities
+- **Streaming Responses** - Support for long-running operations
+- **Parameter Validation** - Using Zod schemas
+- **Claude & Cursor Integration** - Ready-made utilities for AI assistants
 
-## Architecture & Design
+## Getting Started
 
-The MCP Server is built with scalability, resilience, and security in mind:
+### Prerequisites
 
-- **High-Performance Runtime:** Powered by Bun for fast startup, efficient memory utilization, and native TypeScript support.
-- **Real-time Communication:** Employs Server-Sent Events (SSE) for continuous, real-time data updates.
-- **Modular & Extensible:** Designed to support plugins, add-ons, and custom automation scripts, allowing for easy expansion.
-- **Secure API Integration:** Implements token-based authentication, rate limiting, and adherence to best security practices.
+- Node.js 16+
+- Home Assistant instance (or you can use the mock implementations for testing)
 
-_For a deeper dive into the system architecture, please refer to our [Architecture Documentation](docs/ARCHITECTURE.md) (if available)._ 
+### Installation
 
-## Installation
+```bash
+# Clone the repository
+cd /data
+git clone https://git.carriere.cloud/alex/homeassistant-mcp.git
 
-### Basic Setup
+# Install dependencies 
+cd homeassistant-mcp
 
-1. **Install Bun:** If Bun is not installed:
+npm install -g bun
+bun install
+
+# Build the project
+npm run build
+
+```
+
+### Running the Server
+
+```bash
+# Start with standard I/O transport (for AI assistant integration)
+npm start -- --stdio
+
+# Start with HTTP transport (for API access)
+npm start -- --http
+
+# Start with both transports
+npm start -- --stdio --http
+```
+
+### Configuration
+
+Configure the server using environment variables or a `.env` file:
+
+```dotenv
+# Server configuration
+PORT=3000
+NODE_ENV=development
+
+# Execution settings
+EXECUTION_TIMEOUT=30000
+STREAMING_ENABLED=true
+
+# Transport settings
+USE_STDIO_TRANSPORT=true
+USE_HTTP_TRANSPORT=true
+
+# Debug and logging
+DEBUG_MODE=false
+DEBUG_STDIO=false
+DEBUG_HTTP=false
+SILENT_STARTUP=false
+
+# CORS settings
+CORS_ORIGIN=*
+```
+
+## Architecture
+
+The MCP server is built with a layered architecture:
+
+1. **Transport Layer** - Handles communication protocols (stdio, HTTP)
+2. **Middleware Layer** - Processes requests through a pipeline
+3. **Tool Layer** - Implements specific functionality
+4. **Resource Layer** - Manages stateful resources
+
+### Tools
+
+Tools are the primary way to add functionality to the MCP server. Each tool:
+
+- Has a unique name
+- Accepts typed parameters
+- Returns typed results
+- Can stream partial results
+- Validates inputs and outputs
+
+Example tool registration:
+
+```typescript
+import { LightsControlTool } from "./tools/homeassistant/lights.tool.js";
+import { ClimateControlTool } from "./tools/homeassistant/climate.tool.js";
+
+// Register tools
+server.registerTool(new LightsControlTool());
+server.registerTool(new ClimateControlTool());
+```
+
+### API
+
+When running with HTTP transport, the server provides a JSON-RPC 2.0 API:
+
+- `POST /api/mcp/jsonrpc` - Execute a tool
+- `GET /api/mcp/stream` - Connect to SSE stream for real-time updates
+- `GET /api/mcp/info` - Get server information
+- `GET /health` - Health check endpoint
+
+## Integration with AI Models
+
+### Claude Integration
+
+```typescript
+import { createClaudeToolDefinitions } from "./mcp/index.js";
+
+// Generate Claude-compatible tool definitions
+const claudeTools = createClaudeToolDefinitions([
+  new LightsControlTool(),
+  new ClimateControlTool()
+]);
+
+// Use with Claude API
+const messages = [
+  { role: "user", content: "Turn on the lights in the living room" }
+];
+
+const response = await claude.messages.create({
+  model: "claude-3-opus-20240229",
+  messages,
+  tools: claudeTools
+});

+
+### Cursor Integration
+
+To use the Home Assistant MCP server with Cursor, add the following to your `.cursor/config/config.json` file:
+
+```json
+{
+  "mcpServers": {
+    "homeassistant-mcp": {
+      "command": "bash",
+      "args": ["-c", "cd ${workspaceRoot} && bun run dist/index.js --stdio 2>/dev/null | grep -E '\\{\"jsonrpc\":\"2\\.0\"'"],
+      "env": {
+        "NODE_ENV": "development",
+        "USE_STDIO_TRANSPORT": "true",
+        "DEBUG_STDIO": "true"
+      }
+    }
+  }
+}
+```
+
+This configuration:
+1. Runs the MCP server with stdio transport
+2. Redirects all stderr output to /dev/null
+3. Uses grep to filter stdout for lines containing `{"jsonrpc":"2.0"`, ensuring clean JSON-RPC output
+
+#### Troubleshooting Cursor Integration
+
+If you encounter a "failed to create client" error when using the MCP server with Cursor:
+
+1. Make sure you're using the correct command and arguments in your Cursor configuration
+   - The bash script approach ensures only valid JSON-RPC messages reach Cursor
+   - Ensure the server is built by running `bun run build` before trying to connect
+
+2. Ensure the server is properly outputting JSON-RPC messages to stdout:
    ```bash
-   curl -fsSL https://bun.sh/install | bash
+   bun run dist/index.js --stdio 2>/dev/null | grep -E '\{"jsonrpc":"2\.0"' > json_only.txt
    ```
+   Then examine json_only.txt to verify it contains only valid JSON-RPC messages.
 
-2. **Clone the Repository:**
-   ```bash
-   git clone https://github.com/jango-blockchained/homeassistant-mcp.git
-   cd homeassistant-mcp
-   ```
+3. Make sure grep is installed on your system (it should be available by default on most systems)
 
-3. **Install Dependencies:**
-   ```bash
-   bun install
-   ```
-
-4. **Build the Project:**
+4. Try rebuilding the server with:
    ```bash
    bun run build
    ```
+   
+5. Enable debug mode by setting `DEBUG_STDIO=true` in the environment variables
 
-### Docker Setup (Recommended)
-
-1. **Clone the Repository:**
-   ```bash
-   git clone https://github.com/jango-blockchained/homeassistant-mcp.git
-   cd homeassistant-mcp
+If the issue persists, you can try:
+1. Restarting Cursor
+2. Clearing Cursor's cache (Help > Developer > Clear Cache and Reload)
+3. Using a similar approach with Node.js:
+   ```json
+   {
+     "command": "bash",
+     "args": ["-c", "cd ${workspaceRoot} && node dist/index.js --stdio 2>/dev/null | grep -E '\\{\"jsonrpc\":\"2\\.0\"'"]
+   }
    ```
 
-2. **Configure Environment:**
-   ```bash
-   cp .env.example .env
-   ```
-   Customize the `.env` file with your Home Assistant configuration.
-
-3. **Deploy with Docker Compose:**
-   ```bash
-   docker compose up -d
-   ```
-   - View logs: `docker compose logs -f`
-   - Stop the server: `docker compose down`
-
-4. **Update the Application:**
-   ```bash
-   git pull && docker compose up -d --build
-   ```
-
-## Usage
-
-Once the server is running, open your browser at [http://localhost:3000](http://localhost:3000). For real-time device updates, integrate the SSE endpoint in your application:
-
-```javascript
-const eventSource = new EventSource('http://localhost:3000/subscribe_events?token=YOUR_TOKEN&domain=light');
-
-eventSource.onmessage = (event) => {
-  const data = JSON.parse(event.data);
-  console.log('Update received:', data);
-};
-```

+   USE_STDIO_TRANSPORT=true
+   ```
+
+2. Run the server using the stdio-start script:
+   ```bash
+   ./stdio-start.sh
+   ```
+
+   Available options:
+   ```
+   ./stdio-start.sh --debug    # Enable debug mode
+   ./stdio-start.sh --rebuild  # Force rebuild
+   ./stdio-start.sh --help     # Show help
+   ```
+
+When running in stdio mode:
+- The server communicates via stdin/stdout using JSON-RPC 2.0 format
+- No HTTP server is started
+- Console logging is disabled to avoid polluting the stdio stream
+- All logs are written to the log files in the `logs/` directory

+### JSON-RPC 2.0 Message Format
+
+## Usage
+
+### Using NPX (Easiest)
+
+The simplest way to use the Home Assistant MCP server is through NPX:
+
+```bash
+# Start the server in stdio mode
+npx homeassistant-mcp
+```
+
+This will automatically:
+1. Start the server in stdio mode
+2. Output JSON-RPC messages to stdout
+3. Send log messages to stderr
+4. Create a logs directory if it doesn't exist
+
+You can redirect stderr to hide logs and only see the JSON-RPC output:
+
+```bash
+npx homeassistant-mcp 2>/dev/null
+```
+
+### Manual Installation
+
+If you prefer to install the package globally or locally:
+
+```bash
+# Install globally
+npm install -g homeassistant-mcp
+
+# Then run
+homeassistant-mcp
+```
+
+Or install locally:
+
+```bash
+# Install locally
+npm install homeassistant-mcp
+
+# Then run using npx
+npx homeassistant-mcp
+```

-
-Manages rate limiting for IP addresses to prevent abuse.
-
-**Parameters**:
-- `ip`: IP address to track
-- `maxRequests`: Maximum number of requests allowed (default: 100)
-- `windowMs`: Time window for rate limiting (default: 15 minutes)
-
-**Returns**: `boolean` or throws an error if limit is exceeded
-
-**Example**:
-```typescript
-try {
-  checkRateLimit('127.0.0.1'); // Checks rate limit with default settings
-} catch (error) {
-  // Handle rate limit exceeded
-}
-```
-
-#### `validateRequestHeaders(request: Request, requiredContentType?: string)`
-
-Validates incoming HTTP request headers for security and compliance.
-
-**Parameters**:
-- `request`: The incoming HTTP request

-- Maximum 100 concurrent clients
-- Connections timeout after 5 minutes of inactivity
-- Ping messages are sent every 30 seconds
-- Clients should handle reconnection on connection loss
-
-## Example Implementation
-
-```javascript
-class HomeAssistantSSE {
-  constructor(baseUrl, token) {
-    this.baseUrl = baseUrl;
-    this.token = token;
-    this.eventSource = null;
-    this.reconnectAttempts = 0;
-    this.maxReconnectAttempts = 5;
-    this.reconnectDelay = 1000;
-  }
-
-  connect(options = {}) {
-    const params = new URLSearchParams({
-      token: this.token,
-      ...(options.events && { events: options.events.join(',') }),
-      ...(options.entity_id && { entity_id: options.entity_id }),
-      ...(options.domain && { domain: options.domain })
-    });
-
-    this.eventSource = new EventSource(`${this.baseUrl}/subscribe_events?${params}`);
-
-    this.eventSource.onmessage = (event) => {
-      const data = JSON.parse(event.data);
-      this.handleEvent(data);
-    };
-
-    this.eventSource.onerror = (error) => {
-      console.error('SSE Error:', error);
-      this.handleError(error);
-    };
-  }
-
-  handleEvent(data) {
-    switch (data.type) {
-      case 'connection':
-        this.reconnectAttempts = 0;
-        console.log('Connected:', data);
-        break;
-      case 'ping':
-        // Connection is alive
-        break;
-      case 'error':
-        console.error('Server Error:', data);
-        break;
-      default:
-        // Handle other event types
-        console.log('Event:', data);
-    }
-  }
-
-  handleError(error) {
-    this.eventSource?.close();
-    
-    if (this.reconnectAttempts < this.maxReconnectAttempts) {
-      this.reconnectAttempts++;
-      const delay = this.reconnectDelay * Math.pow(2, this.reconnectAttempts - 1);
-      console.log(`Reconnecting in ${delay}ms (attempt ${this.reconnectAttempts})`);
-      setTimeout(() => this.connect(), delay);
-    } else {
-      console.error('Max reconnection attempts reached');
-    }
-  }
-
-  disconnect() {
-    this.eventSource?.close();
-    this.eventSource = null;
-  }
-}
-
-// Usage example
-const client = new HomeAssistantSSE('http://localhost:3000', 'YOUR_HASS_TOKEN');
-client.connect({
-  events: ['state_changed', 'automation_triggered'],
-  domain: 'light'
-});
-```
-
-## Best Practices
-
-1. **Error Handling**
-   - Implement exponential backoff for reconnection attempts
-   - Handle connection timeouts gracefully
-   - Monitor for rate limit errors
-
-2. **Resource Management**
-   - Close EventSource when no longer needed
-   - Limit subscriptions to necessary events/entities
-   - Handle cleanup on page unload
-
-3. **Security**
-   - Never expose the authentication token in client-side code
-   - Use HTTPS in production
-   - Validate all incoming data
-
-4. **Performance**
-   - Subscribe only to needed events
-   - Implement client-side event filtering
-   - Monitor memory usage for long-running connections
-
-## Troubleshooting
-
-### Common Issues
-
-1. **Connection Failures**
-   - Verify your authentication token is valid
-   - Check server URL is accessible
-   - Ensure proper network connectivity
-   - Verify SSL/TLS configuration if using HTTPS
-
-2. **Missing Events**
-   - Confirm subscription parameters are correct
-   - Check rate limiting status
-   - Verify entity/domain exists
-   - Monitor client-side event handlers
-
-3. **Performance Issues**
-   - Reduce number of subscriptions
-   - Implement client-side filtering
-   - Monitor memory usage
-   - Check network latency
-
-### Debugging Tips
-
-1. Enable console logging:
-```javascript
-const client = new HomeAssistantSSE('http://localhost:3000', 'YOUR_HASS_TOKEN');
-client.debug = true; // Enables detailed logging
-```
-
-2. Monitor network traffic:
-```javascript
-// Add event listeners for connection states
-eventSource.addEventListener('open', () => {
-  console.log('Connection opened');
-});
-
-eventSource.addEventListener('error', (e) => {
-  console.log('Connection error:', e);
-});
-```
-
-3. Track subscription status:
-```javascript
-// Get current subscriptions
-const stats = await fetch('/get_sse_stats', {
-  headers: { 'Authorization': `Bearer ${token}` }
-}).then(r => r.json());
-
-console.log('Current subscriptions:', stats);
-```

-
-## Overview
-
-This document describes the testing setup and practices used in the Home Assistant MCP project. The project uses Bun's test runner for unit and integration testing, with a comprehensive test suite covering security, SSE (Server-Sent Events), middleware, and other core functionalities.
-
-## Test Structure
-
-Tests are organized in two main locations:
-
-1. **Root Level Integration Tests** (`/__tests__/`):
-   ```
-   __tests__/
-   ├── ai/              # AI/ML component tests
-   ├── api/             # API integration tests
-   ├── context/         # Context management tests
-   ├── hass/           # Home Assistant integration tests
-   ├── schemas/         # Schema validation tests
-   ├── security/        # Security integration tests
-   ├── tools/          # Tools and utilities tests
-   ├── websocket/      # WebSocket integration tests
-   ├── helpers.test.ts # Helper function tests
-   ├── index.test.ts   # Main application tests
-   └── server.test.ts  # Server integration tests
-   ```
-
-2. **Component Level Unit Tests** (`src/**/`):
-   ```
-   src/
-   ├── __tests__/           # Global test setup and utilities
-   │   └── setup.ts        # Global test configuration
-   ├── component/
-   │   ├── __tests__/      # Component-specific unit tests
-   │   └── component.ts
-   ```
-
-The root level `__tests__` directory contains integration and end-to-end tests that verify the interaction between different components of the system, while the component-level tests focus on unit testing individual modules.
-
-## Test Configuration
-
-### Bun Test Configuration (`bunfig.toml`)
-
-```toml
-[test]
-preload = ["./src/__tests__/setup.ts"]  # Global test setup
-coverage = true                         # Enable coverage by default
-timeout = 30000                         # Test timeout in milliseconds
-testMatch = ["**/__tests__/**/*.test.ts"] # Test file patterns
-```
-
-### Bun Scripts
-
-Available test commands in `package.json`:
-
-```bash
-# Run all tests
-bun test
-
-# Watch mode for development
-bun test --watch
-
-# Generate coverage report
-bun test --coverage
-
-# Run linting
-bun run lint
-
-# Format code
-bun run format
-```
-
-## Test Setup
-
-### Global Configuration
-
-The project uses a global test setup file (`src/__tests__/setup.ts`) that provides:
-
-- Environment configuration
-- Mock utilities
-- Test helper functions
-- Global test lifecycle hooks
-
-### Test Environment
-
-Tests run with the following configuration:
-
-- Environment variables are loaded from `.env.test`
-- Console output is suppressed during tests (unless DEBUG=true)
-- JWT secrets and tokens are automatically configured for testing
-- Rate limiting and other security features are properly initialized
-
-## Running Tests
-
-To run the test suite:
-
-```bash
-# Basic test run
-bun test
-
-# Run tests with coverage
-bun test --coverage
-
-# Run specific test file
-bun test path/to/test.test.ts
-
-# Run tests in watch mode
-bun test --watch
-
-# Run tests with debug output
-DEBUG=true bun test
-
-# Run tests with increased timeout
-bun test --timeout 60000
-
-# Run tests matching a pattern
-bun test --pattern "auth"
-```
-
-### Test Environment Setup
-
-1. **Prerequisites**:
-   - Bun >= 1.0.0
-   - Node.js dependencies (see package.json)
-
-2. **Environment Files**:
-   - `.env.test` - Test environment variables
-   - `.env.development` - Development environment variables
-
-3. **Test Data**:
-   - Mock responses in `__tests__/mock-responses/`
-   - Test fixtures in `__tests__/fixtures/`
-
-### Continuous Integration
-
-The project uses GitHub Actions for CI/CD. Tests are automatically run on:
-- Pull requests
-- Pushes to main branch
-- Release tags
-
-## Writing Tests
-
-### Test File Naming
-
-- Test files should be placed in a `__tests__` directory adjacent to the code being tested
-- Test files should be named `*.test.ts`
-- Test files should mirror the structure of the source code
-
-### Test Structure
-
-```typescript
-import { describe, expect, it, beforeEach } from "bun:test";
-
-describe("Module Name", () => {
-  beforeEach(() => {
-    // Setup for each test
-  });
-
-  describe("Feature/Function Name", () => {
-    it("should do something specific", () => {
-      // Test implementation
-    });
-  });
-});
-```
-
-### Test Utilities
-
-The project provides several test utilities:
-
-```typescript
-import { testUtils } from "../__tests__/setup";
-
-// Available utilities:
-- mockWebSocket()      // Mock WebSocket for SSE tests
-- mockResponse()       // Mock HTTP response for API tests
-- mockRequest()        // Mock HTTP request for API tests
-- createTestClient()   // Create test SSE client
-- createTestEvent()    // Create test event
-- createTestEntity()   // Create test Home Assistant entity
-- wait()              // Helper to wait for async operations
-```
-
-## Testing Patterns
-
-### Security Testing
-
-Security tests cover:
-- Token validation and encryption
-- Rate limiting
-- Request validation
-- Input sanitization
-- Error handling
-
-Example:
-```typescript
-describe("Security Features", () => {
-  it("should validate tokens correctly", () => {
-    const payload = { userId: "123", role: "user" };
-    const token = jwt.sign(payload, validSecret, { expiresIn: "1h" });
-    const result = TokenManager.validateToken(token, testIp);
-    expect(result.valid).toBe(true);
-  });
-});
-```
-
-### SSE Testing
-
-SSE tests cover:
-- Client authentication
-- Message broadcasting
-- Rate limiting
-- Subscription management
-- Client cleanup
-
-Example:
-```typescript
-describe("SSE Features", () => {
-  it("should authenticate valid clients", () => {
-    const client = createTestClient("test-client");
-    const result = sseManager.addClient(client, validToken);
-    expect(result?.authenticated).toBe(true);
-  });
-});
-```
-
-### Middleware Testing
-
-Middleware tests cover:
-- Request validation
-- Input sanitization
-- Error handling
-- Response formatting
-
-Example:
-```typescript
-describe("Middleware", () => {
-  it("should sanitize HTML in request body", () => {
-    const req = mockRequest({
-      body: { text: '<script>alert("xss")</script>' }
-    });
-    sanitizeInput(req, res, next);
-    expect(req.body.text).toBe("");
-  });
-});
-```
-
-### Integration Testing
-
-Integration tests in the root `__tests__` directory cover:
-
-- **AI/ML Components**: Testing machine learning model integrations and predictions
-- **API Integration**: End-to-end API route testing
-- **Context Management**: Testing context persistence and state management
-- **Home Assistant Integration**: Testing communication with Home Assistant
-- **Schema Validation**: Testing data validation across the application
-- **Security Integration**: Testing security features in a full system context
-- **WebSocket Communication**: Testing real-time communication
-- **Server Integration**: Testing the complete server setup and configuration
-
-Example integration test:
-```typescript
-describe("API Integration", () => {
-  it("should handle a complete authentication flow", async () => {
-    // Setup test client
-    const client = await createTestClient();
-    
-    // Test registration
-    const regResponse = await client.register(testUser);
-    expect(regResponse.status).toBe(201);
-    
-    // Test authentication
-    const authResponse = await client.authenticate(testCredentials);
-    expect(authResponse.status).toBe(200);
-    expect(authResponse.body.token).toBeDefined();
-    
-    // Test protected endpoint access
-    const protectedResponse = await client.get("/api/protected", {
-      headers: { Authorization: `Bearer ${authResponse.body.token}` }
-    });
-    expect(protectedResponse.status).toBe(200);
-  });
-});
-```
-
-## Security Middleware Testing
-
-### Utility Function Testing
-
-The security middleware now uses a utility-first approach, which allows for more granular and comprehensive testing. Each security function is now independently testable, improving code reliability and maintainability.
-
-#### Key Utility Functions
-
-1. **Rate Limiting (`checkRateLimit`)**
-   - Tests multiple scenarios:
-     - Requests under threshold
-     - Requests exceeding threshold
-     - Rate limit reset after window expiration
-   
-   ```typescript
-   // Example test
-   it('should throw when requests exceed threshold', () => {
-     const ip = '127.0.0.2';
-     for (let i = 0; i < 11; i++) {
-       if (i < 10) {
-         expect(() => checkRateLimit(ip, 10)).not.toThrow();
-       } else {
-         expect(() => checkRateLimit(ip, 10)).toThrow('Too many requests from this IP');
-       }
-     }
-   });
-   ```
-
-2. **Request Validation (`validateRequestHeaders`)**
-   - Tests content type validation
-   - Checks request size limits
-   - Validates authorization headers
-   
-   ```typescript
-   it('should reject invalid content type', () => {
-     const mockRequest = new Request('http://localhost', {
-       method: 'POST',
-       headers: { 'content-type': 'text/plain' }
-     });
-     expect(() => validateRequestHeaders(mockRequest)).toThrow('Content-Type must be application/json');
-   });
-   ```
-
-3. **Input Sanitization (`sanitizeValue`)**
-   - Sanitizes HTML tags
-   - Handles nested objects
-   - Preserves non-string values
-   
-   ```typescript
-   it('should sanitize HTML tags', () => {
-     const input = '<script>alert("xss")</script>Hello';
-     const sanitized = sanitizeValue(input);
-     expect(sanitized).toBe('&lt;script&gt;alert(&quot;xss&quot;)&lt;/script&gt;Hello');
-   });
-   ```
-
-4. **Security Headers (`applySecurityHeaders`)**
-   - Verifies correct security header application
-   - Checks CSP, frame options, and other security headers
-   
-   ```typescript
-   it('should apply security headers', () => {
-     const mockRequest = new Request('http://localhost');
-     const headers = applySecurityHeaders(mockRequest);
-     expect(headers['content-security-policy']).toBeDefined();
-     expect(headers['x-frame-options']).toBeDefined();
-   });
-   ```
-
-5. **Error Handling (`handleError`)**
-   - Tests error responses in production and development modes
-   - Verifies error message and stack trace inclusion
-   
-   ```typescript
-   it('should include error details in development mode', () => {
-     const error = new Error('Test error');
-     const result = handleError(error, 'development');
-     expect(result).toEqual({
-       error: true,
-       message: 'Internal server error',
-       error: 'Test error',
-       stack: expect.any(String)
-     });
-   });
-   ```
-
-### Testing Philosophy
-
-- **Isolation**: Each utility function is tested independently
-- **Comprehensive Coverage**: Multiple scenarios for each function
-- **Predictable Behavior**: Clear expectations for input and output
-- **Error Handling**: Robust testing of error conditions
-
-### Best Practices
-
-1. Use minimal, focused test cases
-2. Test both successful and failure scenarios
-3. Verify input sanitization and security measures
-4. Mock external dependencies when necessary
-
-### Running Security Tests
-
-```bash
-# Run all tests
-bun test
-
-# Run specific security tests
-bun test __tests__/security/
-```
-
-### Continuous Improvement
-
-- Regularly update test cases
-- Add new test scenarios as security requirements evolve
-- Perform periodic security audits
-
-## Best Practices
-
-1. **Isolation**: Each test should be independent and not rely on the state of other tests.
-2. **Mocking**: Use the provided mock utilities for external dependencies.
-3. **Cleanup**: Clean up any resources or state modifications in `afterEach` or `afterAll` hooks.
-4. **Descriptive Names**: Use clear, descriptive test names that explain the expected behavior.
-5. **Assertions**: Make specific, meaningful assertions rather than general ones.
-6. **Setup**: Use `beforeEach` for common test setup to avoid repetition.
-7. **Error Cases**: Test both success and error cases for complete coverage.
-
-## Coverage
-
-The project aims for high test coverage, particularly focusing on:
-- Security-critical code paths
-- API endpoints
-- Data validation
-- Error handling
-- Event broadcasting
-
-Run coverage reports using:
-```bash
-bun test --coverage
-```
-
-## Debugging Tests
-
-To debug tests:
-1. Set `DEBUG=true` to enable console output during tests
-2. Use the `--watch` flag for development
-3. Add `console.log()` statements (they're only shown when DEBUG is true)
-4. Use the test utilities' debugging helpers
-
-### Advanced Debugging
-
-1. **Using Node Inspector**:
-   ```bash
-   # Start tests with inspector
-   bun test --inspect
-   
-   # Start tests with inspector and break on first line
-   bun test --inspect-brk
-   ```
-
-2. **Using VS Code**:
-   ```jsonc
-   // .vscode/launch.json
-   {
-     "version": "0.2.0",
-     "configurations": [
-       {
-         "type": "bun",
-         "request": "launch",
-         "name": "Debug Tests",
-         "program": "${workspaceFolder}/node_modules/bun/bin/bun",

-## Security Middleware Troubleshooting
-
-### Common Issues and Solutions
-
-#### Rate Limiting Problems
-
-**Symptom**: Unexpected 429 (Too Many Requests) errors
-
-**Possible Causes**:
-- Misconfigured rate limit settings
-- Shared IP addresses (e.g., behind NAT)
-- Aggressive client-side retry mechanisms
-
-**Solutions**:
-1. Adjust rate limit parameters
-   ```typescript
-   // Customize rate limit for specific scenarios
-   checkRateLimit(ip, maxRequests = 200, windowMs = 30 * 60 * 1000)
-   ```
-
-2. Implement more granular rate limiting
-   - Use different limits for different endpoints
-   - Consider user authentication level
-
-#### Request Validation Failures
-
-**Symptom**: 400 or 415 status codes on valid requests
-
-**Possible Causes**:
-- Incorrect `Content-Type` header
-- Large request payloads
-- Malformed authorization headers
-
-**Debugging Steps**:
-1. Verify request headers
-   ```typescript
-   // Check content type and size
-   validateRequestHeaders(request, 'application/json')
-   ```
-
-2. Log detailed validation errors
-   ```typescript
-   try {
-     validateRequestHeaders(request);
-   } catch (error) {
-     console.error('Request validation failed:', error.message);
-   }
-   ```
-
-#### Input Sanitization Issues
-
-**Symptom**: Unexpected data transformation or loss
-
-**Possible Causes**:
-- Complex nested objects
-- Non-standard input formats
-- Overly aggressive sanitization
-
-**Troubleshooting**:
-1. Test sanitization with various input types
-   ```typescript
-   const input = {
-     text: '<script>alert("xss")</script>',
-     nested: { html: '<img src="x" onerror="alert(1)">World' }
-   };
-   const sanitized = sanitizeValue(input);
-   ```
-
-2. Custom sanitization for specific use cases
-   ```typescript
-   function customSanitize(value) {
-     // Add custom sanitization logic
-     return sanitizeValue(value);
-   }
-   ```
-
-#### Security Header Configuration
-
-**Symptom**: Missing or incorrect security headers
-
-**Possible Causes**:
-- Misconfigured Helmet options
-- Environment-specific header requirements
-
-**Solutions**:
-1. Custom security header configuration
-   ```typescript
-   const customHelmetConfig = {
-     contentSecurityPolicy: {
-       directives: {
-         defaultSrc: ["'self'"],
-         scriptSrc: ["'self'", 'trusted-cdn.com']
-       }
-     }
-   };
-   applySecurityHeaders(request, customHelmetConfig);
-   ```
-
-#### Error Handling and Logging
-
-**Symptom**: Inconsistent error responses
-
-**Possible Causes**:
-- Incorrect environment configuration
-- Unhandled error types
-
-**Debugging Techniques**:
-1. Verify environment settings
-   ```typescript
-   const errorResponse = handleError(error, process.env.NODE_ENV);
-   ```
-
-2. Add custom error handling
-   ```typescript
-   function enhancedErrorHandler(error, env) {
-     // Add custom logging or monitoring
-     console.error('Security error:', error);
-     return handleError(error, env);
-   }
-   ```
-
-### Performance and Security Monitoring
-
-1. **Logging**
-   - Enable debug logging for security events
-   - Monitor rate limit and validation logs
-
-2. **Metrics**
-   - Track rate limit hit rates
-   - Monitor request validation success/failure ratios

+# Speech-to-Text Examples
+
+This directory contains examples demonstrating how to use the speech-to-text integration with wake word detection.
+
+## Prerequisites
+
+1. Make sure you have Docker installed and running
+2. Build and start the services:
+   ```bash
+   docker-compose up -d
+   ```
+
+## Running the Example
+
+1. Install dependencies:
+   ```bash
+   npm install
+   ```
+
+2. Run the example:
+   ```bash
+   npm run example:speech
+   ```
+
+   Or using `ts-node` directly:
+   ```bash
+   npx ts-node examples/speech-to-text-example.ts
+   ```
+
+## Features Demonstrated
+
+1. **Wake Word Detection**
+   - Listens for wake words: "hey jarvis", "ok google", "alexa"
+   - Automatically saves audio when wake word is detected
+   - Transcribes the detected speech
+
+2. **Manual Transcription**
+   - Example of how to transcribe audio files manually
+   - Supports different models and configurations
+
+3. **Event Handling**
+   - Wake word detection events
+   - Transcription results
+   - Progress updates
+   - Error handling
+
+## Example Output
+
+When a wake word is detected, you'll see output like this:
+
+```
+🎤 Wake word detected!
+  Timestamp: 20240203_123456
+  Audio file: /path/to/audio/wake_word_20240203_123456.wav
+  Metadata file: /path/to/audio/wake_word_20240203_123456.wav.json
+
+📝 Transcription result:
+  Full text: This is what was said after the wake word.
+
+  Segments:
+    1. [0.00s - 1.52s] (95.5% confidence)
+       "This is what was said"
+    2. [1.52s - 2.34s] (98.2% confidence)
+       "after the wake word."
+```
+
+## Customization
+
+You can customize the behavior by:
+
+1. Changing the wake word models in `docker/speech/Dockerfile`
+2. Modifying transcription options in the example file
+3. Adding your own event handlers
+4. Implementing different audio processing logic
+
+## Troubleshooting
+
+1. **Docker Issues**
+   - Make sure Docker is running
+   - Check container logs: `docker-compose logs fast-whisper`
+   - Verify container is up: `docker ps`
+
+2. **Audio Issues**
+   - Check audio device permissions
+   - Verify audio file format (WAV files recommended)
+   - Check audio file permissions
+
+3. **Performance Issues**
+   - Try using a smaller model (tiny.en or base.en)
+   - Adjust beam size and patience parameters
+   - Consider using GPU acceleration if available
