### 🐛 Debugging & Development

#### Direct MCP Testing
```bash
# Test individual tools directly
echo '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"navigate","arguments":{"url":"https://example.com"}}}' | node index.js

echo '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"evaluate","arguments":{"script":"document.title"}}}' | node index.js

echo '{"jsonrpc":"2.0","id":3,"method":"tools/call","params":{"name":"screenshot","arguments":{"name":"debug.png"}}}' | node index.js
```

#### Chrome DevTools Protocol Debugging
```bash
# Manual CDP connection test
node -e "
const { WebSocket } = require('ws');
const { spawn } = require('child_process');

const chrome = spawn('/usr/bin/chromium-browser', [
  '--headless', '--remote-debugging-port=9227'
]);

setTimeout(() => {
  fetch('http://localhost:9227/json')
    .then(r => r.json())
    .then(tabs => {
      console.log('Available tabs:', tabs.length);
      const ws = new WebSocket(tabs[0].webSocketDebuggerUrl);
      ws.on('open', () => {
        console.log('CDP WebSocket connected!');
        ws.send(JSON.stringify({id: 1, method: 'Runtime.evaluate', params: {expression: '2+2'}}));
      });
      ws.on('message', (data) => {
        console.log('CDP Response:', JSON.parse(data));
        chrome.kill();
        process.exit(0);
      });
    });
}, 2000);
"
```

#### Performance Monitoring
```bash
# Monitor system resources during operation
htop &
echo '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"navigate","arguments":{"url":"https://httpbin.org/delay/5"}}}' | time node index.js

# Check memory usage
ps aux | grep chromium
free -h
```

#### Network Debugging
```bash
# Check if debugging port is accessible
curl -s http://localhost:9222/json | jq '.[] | {id, title, type}'

# Monitor WebSocket traffic (install websocat)
websocat ws://localhost:9222/devtools/page/[TAB_ID] --text -v
```

### 🔍 Common Debugging Scenarios

#### 1. WebSocket Connection Issues
```bash
# Symptoms: "CDP command timeout" errors
# Check if chrome debugging port is running
lsof -i :9222

# Test manual connection
node -e "
const { WebSocket } = require('ws');
const ws = new WebSocket('ws://localhost:9222/devtools/browser');
ws.on('open', () => console.log('✓ WebSocket OK'));
ws.on('error', (e) => console.log('✗ WebSocket Error:', e.message));
setTimeout(() => process.exit(0), 2000);
"
```

#### 2. Chrome Process Issues  
```bash
# Symptoms: Browser won't start or hangs
# Kill any stuck processes
pkill -f chromium-browser
pkill -f remote-debugging-port

# Test chrome startup manually
timeout 10s /usr/bin/chromium-browser --headless --remote-debugging-port=9223 --no-sandbox

# Check chrome logs
journalctl --user -u chromium --since "1 hour ago"
```

#### 3. Element Selection Problems
```bash
# Debug CSS selectors interactively
echo '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"evaluate","arguments":{"script":"document.querySelectorAll(\"button\").length"}}}' | node index.js

# Get element information
echo '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"evaluate","arguments":{"script":"document.querySelector(\"#mybutton\") ? \"found\" : \"not found\""}}}' | node index.js
```

#### 4. Memory and Performance Issues
```bash
# Monitor memory during operation
watch -n 1 'ps aux | grep -E "(chromium|node)" | grep -v grep'

# Chrome memory debugging
echo '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"evaluate","arguments":{"script":"JSON.stringify(performance.memory)"}}}' | node index.js
```

### 🎯 Advanced Debugging Features

#### Enable Verbose Logging
```bash
# Set environment variables for detailed output
export DEBUG=puppeteer:*
export NODE_ENV=development

# Run with detailed Chrome logs
/usr/bin/chromium-browser --headless --enable-logging --log-level=0 --remote-debugging-port=9222
```

#### CDP Message Tracing
```bash
# Create debug version with message logging
cp index.js debug-index.js

# Add to sendCDPCommand method:
# console.log('→ CDP:', JSON.stringify(command));
# console.log('← CDP:', JSON.stringify(response));

node debug-index.js
```

#### Integration with Browser DevTools
```bash
# Connect regular Chrome DevTools to the headless instance
# 1. Start the MCP server
# 2. Open regular Chrome/Chromium
# 3. Navigate to: chrome://inspect
# 4. Click "Configure..." and add localhost:9222
# 5. Click "inspect" on the page you want to debug
```

### 📊 Performance Benchmarks

#### Startup Time Comparison
```bash
# Direct CDP (v1.3.0)
time echo '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"evaluate","arguments":{"script":"Date.now()"}}}' | node index.js

# Puppeteer version (v1.2.0)  
git checkout main
time echo '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"evaluate","arguments":{"script":"Date.now()"}}}' | node index.js
```

#### Memory Usage Monitoring
```bash
# Before operation
free -h && ps aux | grep -E "(chromium|node)" | grep -v grep

# During operation (run in another terminal)
watch -n 1 'echo "=== $(date) ===" && free -h && echo && ps aux | grep -E "(chromium|node)" | grep -v grep'
```

### 🚨 Error Codes & Solutions

| Error | Cause | Solution |
|-------|-------|----------|
| `CDP command timeout` | WebSocket connection lost | Restart browser, check port availability |
| `WebSocket not ready` | Chrome not fully started | Increase startup delay, check chrome process |
| `Element not found` | CSS selector invalid | Verify selector with `evaluate` tool |
| `ECONNREFUSED` | Debugging port blocked | Check firewall, kill existing chrome processes |
| `Navigation timeout` | Page loading issues | Check network, increase timeout, try simpler page |

### 🔧 Customization & Extension

#### Adding New MCP Tools
```javascript
// In index.js, add to tools array:
{
  name: 'my_custom_tool',
  description: 'My custom functionality',
  inputSchema: {
    type: 'object',
    properties: {
      param: { type: 'string', description: 'Parameter description' }
    },
    required: ['param']
  }
}

// Add to switch statement in CallToolRequestSchema handler:
case 'my_custom_tool':
  return await this.myCustomTool(args.param);

// Implement the method:
async myCustomTool(param) {
  await this.ensureChromium();
  const result = await this.sendCDPCommand('Page.navigate', { url: param });
  return { content: [{ type: 'text', text: `Custom result: ${result}` }] };
}
```

#### Chrome Launch Options
```javascript
// Modify in startChromium() method:
const customArgs = [
  '--headless',
  '--no-sandbox',
  '--disable-extensions',
  '--disable-plugins',
  '--disable-background-timer-throttling',
  '--disable-backgrounding-occluded-windows',
  '--disable-renderer-backgrounding',
  '--remote-debugging-port=9222',
  '--window-size=1920,1080',        // Custom viewport
  '--user-agent=CustomUA/1.0',      // Custom user agent
  '--disable-web-security',         // For CORS testing
  '--allow-running-insecure-content' // For mixed content
];
```

## 🌐 Cross-Platform ARM64 Compatibility

### **Platform Support Matrix**

| Platform | Status | Chrome Path | Installation Method | Notes |
|----------|--------|-------------|---------------------|--------|
| **Linux ARM64** ✅ | **Fully Supported** | `/usr/bin/chromium-browser` | `apt install chromium-browser` | Tested on Raspberry Pi OS |
| **macOS Apple Silicon** ⚠️ | **Requires Modifications** | `/Applications/Google Chrome.app/Contents/MacOS/Google Chrome` | Download from Google or `brew install chromium` | Need path and flag updates |
| **Windows ARM64** ❓ | **Untested** | `C:\Program Files\Google\Chrome\Application\chrome.exe` | Download from Google | Would need Windows-specific changes |

### **macOS Apple Silicon Setup**

#### **Prerequisites**
```bash
# Install Homebrew if not already installed
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# Install Node.js and Chromium
brew install node chromium --no-quarantine
```

#### **Required Code Changes**
Currently, the server is optimized for Linux ARM64. For macOS compatibility, modify `index.js`:

```javascript
// Detect platform and set appropriate chrome path
function getChromePath() {
  const platform = process.platform;
  
  switch(platform) {
    case 'linux':
      return '/usr/bin/chromium-browser';
    case 'darwin': // macOS
      // Try multiple possible paths
      const macPaths = [
        '/Applications/Google Chrome.app/Contents/MacOS/Google Chrome',
        '/Applications/Chromium.app/Contents/MacOS/Chromium',
        '/opt/homebrew/bin/chromium'
      ];
      
      for (const path of macPaths) {
        if (require('fs').existsSync(path)) {
          return path;
        }
      }
      throw new Error('Chrome/Chromium not found on macOS');
    case 'win32':
      return 'C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe';
    default:
      throw new Error(`Unsupported platform: ${platform}`);
  }
}

// Update startChromium method
async startChromium() {
  const chromePath = getChromePath();
  const platform = process.platform;
  
  // Platform-specific arguments
  const baseArgs = [
    '--headless',
    '--disable-extensions',
    '--disable-plugins',
    `--remote-debugging-port=${debuggingPort}`,
    '--no-first-run',
    '--disable-gpu',
    '--window-size=1280,720'
  ];
  
  // Add Linux-specific sandbox flags
  if (platform === 'linux') {
    baseArgs.push('--no-sandbox', '--disable-setuid-sandbox');
  }
  
  // Add macOS-specific flags if needed
  if (platform === 'darwin') {
    baseArgs.push('--disable-dev-shm-usage');
  }
  
  chromiumProcess = spawn(chromePath, baseArgs);
  // ... rest of method
}
```

### **macOS-Specific Issues & Solutions**

#### **1. "Chromium is damaged" Error**
```bash
# Remove quarantine flag if downloading manually
sudo xattr -r -d com.apple.quarantine /Applications/Chromium.app

# Or install via Homebrew with no-quarantine flag
brew install chromium --no-quarantine
```

#### **2. Chrome vs Chromium Choice**
```bash
# Option 1: Use Google Chrome (recommended)
# Download from: https://www.google.com/chrome/
# Path: /Applications/Google Chrome.app/Contents/MacOS/Google Chrome

# Option 2: Use Chromium via Homebrew
brew install chromium --no-quarantine
# Path: /opt/homebrew/bin/chromium
```

#### **3. Permission Issues**
```bash
# Ensure Chrome has required permissions
# System Preferences > Security & Privacy > Privacy tab
# Grant Camera, Microphone access if needed for specific use cases
```

### **Testing Cross-Platform Compatibility**

#### **Quick Platform Detection Test**
```bash
node -e "
console.log('Platform:', process.platform);
console.log('Architecture:', process.arch);
const fs = require('fs');

const paths = {
  linux: '/usr/bin/chromium-browser',
  darwin: '/Applications/Google Chrome.app/Contents/MacOS/Google Chrome',
  win32: 'C:\\\\Program Files\\\\Google\\\\Chrome\\\\Application\\\\chrome.exe'
};

const chromePath = paths[process.platform];
console.log('Expected Chrome path:', chromePath);
console.log('Chrome exists:', fs.existsSync(chromePath));
"
```

#### **Cross-Platform MCP Test**
```bash
# Test basic functionality across platforms
echo '{\"jsonrpc\":\"2.0\",\"id\":1,\"method\":\"tools/call\",\"params\":{\"name\":\"evaluate\",\"arguments\":{\"script\":\"navigator.platform\"}}}' | node index.js

# Should return the current platform
```

### **Windows ARM64 Considerations** 
While untested, Windows ARM64 support would need:

```javascript
// Windows-specific chrome path detection
case 'win32':
  const winPaths = [
    'C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe',
    'C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe',
    process.env.LOCALAPPDATA + '\\Google\\Chrome\\Application\\chrome.exe'
  ];
  // Similar path checking logic...
```

### **Performance Differences**

| Platform | Startup Time | Memory Usage | Notes |
|----------|--------------|--------------|--------|
| **Linux ARM64 (Pi 4)** | ~3-4s | ~150MB | Optimized, well-tested |
| **macOS Apple Silicon** | ~2-3s | ~200MB | Faster CPU, more memory |
| **Windows ARM64** | Unknown | Unknown | Would depend on hardware |

### **Contribution Needed**

**We welcome contributions for full cross-platform support!**

- **macOS testers**: Test the proposed changes on Apple Silicon
- **Windows ARM64**: Test on Surface Pro X or similar devices  
- **Performance optimization**: Platform-specific optimizations
- **Installation scripts**: Automated setup for each platform

##  Claude CLI Integration

### Prerequisites
```bash
# Install Claude Code CLI if you haven't already
npm install -g @anthropic-ai/claude-code
```

### Add to Claude CLI
```bash
# From the project directory after cloning
claude mcp add chromium-arm64 "$(pwd)/mcp-wrapper.sh" --scope user
```

### Verify Connection
```bash
claude mcp list
# Should show: chromium-arm64: /path/to/mcp-wrapper.sh - ✓ Connected
```

### ⚠️ Important: Restart Claude After Adding
**You MUST start a new Claude session after adding the MCP server:**
```bash
# Exit current session if in one
exit
# Start fresh session
claude
```

### Using in Claude CLI

**Ask Claude to use the chromium-arm64 tools:**
```
List available MCP servers and use chromium-arm64 to navigate to https://example.com

Take a screenshot using the chromium-arm64 tool

Use chromium-arm64 to click the button with selector #submit

Fill the email field using chromium-arm64 with test@example.com
```

**Be explicit to avoid Playwright/Puppeteer:**
-  "Use chromium-arm64 to navigate..."
-  "Using the chromium-arm64 tool, take a screenshot"
-  "Open a browser" (might try broken Playwright)
-  "Take a screenshot" (might try broken Puppeteer)

###  Success Example

When working correctly, you'll see:
```
You: Use chromium-arm64 to navigate to https://httpbin.org/json and show me what you see

Claude: I'll navigate to https://httpbin.org/json using the chromium-arm64 tool.

[Uses chromium-arm64.navigate tool]

The page displays a JSON object with a slideshow structure containing:
- Author: "Yours Truly"
- Date: "date of publication"
- Title: "Sample Slide Show"
...
```

##  Usage Examples

### Python API
```python
import simple_browser

# Navigate to any website
result = simple_browser.browser_navigate("https://example.com")
print(result)  # "Successfully navigated to https://example.com"

# Take a screenshot
screenshot = simple_browser.browser_screenshot("homepage.png")
print(screenshot)  # "Screenshot saved to /tmp/homepage.png"

# Execute JavaScript
title = simple_browser.browser_evaluate("document.title")
print(title)  # Website title

# Extract page content
content = simple_browser.browser_get_content("text")
print(content[:100])  # First 100 chars of page text
```
