## 🔧 Dependencies & Installation

### **📦 What's Included (Standalone)**

- `@modelcontextprotocol/sdk` - MCP protocol support
- `node-fetch` - HTTP requests
- `cheerio` - HTML parsing  
- `html-to-text` - HTML to text conversion

### **🚀 Optional Enhancements**
For even better text formatting, install terminal browsers:

# Ubuntu/Debian  
sudo apt install lynx w3m links elinks

# CentOS/RHEL
sudo yum install lynx w3m links elinks
```

### **💡 How It Works**
1. **First Choice**: Uses terminal browsers (lynx, w3m, links) if available
2. **Automatic Fallback**: Uses built-in fetch+html-to-text if no browsers found
3. **Always Works**: Never fails due to missing dependencies

## 🛠️ Terminal Browser Support

### **Supported Browsers**
- **lynx** - Best text formatting, recommended
- **w3m** - Good table support, images in some terminals
- **links** - Interactive features, mouse support
- **elinks** - Enhanced links with more features

### **Installation Commands**
```bash
# macOS (Homebrew)
brew install lynx w3m links

# Ubuntu/Debian
sudo apt install lynx w3m links elinks

# CentOS/RHEL
sudo yum install lynx w3m links elinks
```

### **Auto-Selection Priority**
1. lynx (best formatting)
2. w3m (good compatibility)
3. links (interactive features)
4. elinks (enhanced features)
5. fetch+html-to-text (always available fallback)

## 🎨 Advanced Usage

### **Custom Content Length**
```json
{
  "url": "https://very-long-page.com",
  "maxLength": 5000
}
```

### **Links Only Mode**
```json
{
  "url": "https://documentation-site.com",
  "format": "links-only",
  "maxLinks": 100
}
```

### **Specific Browser**
```json
{
  "url": "https://example.com",
  "browser": "w3m",
  "extractLinks": false
}
```

## 🔍 Troubleshooting

### **"No terminal browsers found"**
```bash
# Install at least one terminal browser
brew install lynx  # macOS
sudo apt install lynx  # Ubuntu
```

### **"Browser failed" errors**
- The tool automatically falls back to fetch+html-to-text
- Check internet connectivity
- Some sites may block terminal browsers

### **Content too long**
```
Use maxLength parameter to limit output:
Browse https://long-page.com with maxLength=2000
```

1. Check `~/.config/amazonq/mcp.json` syntax
2. Restart Q CLI (`/quit` then `q chat`)
