fastmcp install claude-code src/server.py --with-requirements requirements.txt
# OR
fastmcp install cursor src/server.py --with-requirements requirements.txt
```
---
### Alternative: Manual Configuration (If Claude CLI not available)
If you don't have Claude Code CLI, manually add to your MCP client configuration:
**Claude Desktop - Windows** (`%APPDATA%\Claude\claude_desktop_config.json`)
```json
{
"mcpServers": {
"stealth-browser-full": {
"command": "C:\\path\\to\\stealth-browser-mcp\\venv\\Scripts\\python.exe",
"args": ["C:\\path\\to\\stealth-browser-mcp\\src\\server.py"],
"env": {}
},
"stealth-browser-minimal": {
"command": "C:\\path\\to\\stealth-browser-mcp\\venv\\Scripts\\python.exe",
"args": ["C:\\path\\to\\stealth-browser-mcp\\src\\server.py", "--minimal"],
"env": {}
}
}
}
```
**Claude Desktop - Mac/Linux** (`~/Library/Application Support/Claude/claude_desktop_config.json`)
```json
{
"mcpServers": {
"stealth-browser-full": {
"command": "/path/to/stealth-browser-mcp/venv/bin/python",
"args": ["/path/to/stealth-browser-mcp/src/server.py"],
"env": {}
},
"stealth-browser-custom": {
"command": "/path/to/stealth-browser-mcp/venv/bin/python",
"args": [
"/path/to/stealth-browser-mcp/src/server.py",
"--disable-cdp-functions",
"--disable-dynamic-hooks"
],
"env": {}
}
}
}
```
### 🎛️ **NEW: Customize Your Installation**
Stealth Browser MCP now supports modular tool loading! Disable sections you don't need:
```bash
# Minimal installation (only core browser + element interaction)
python src/server.py --minimal
# Custom installation - disable specific sections
python src/server.py --disable-cdp-functions --disable-dynamic-hooks
# List all 11 available tool sections
python src/server.py --list-sections
```
**Available sections:**
- `browser-management` (11 tools) - Core browser operations
- `element-interaction` (11 tools) - Page interaction and manipulation
- `element-extraction` (9 tools) - Element cloning and extraction
- `file-extraction` (9 tools) - File-based extraction tools
- `network-debugging` (5 tools) - Network monitoring and interception
- `cdp-functions` (13 tools) - Chrome DevTools Protocol execution
- `progressive-cloning` (10 tools) - Advanced element cloning
- `cookies-storage` (3 tools) - Cookie and storage management
- `tabs` (5 tools) - Tab management
- `debugging` (6 tools) - Debug and system tools (includes new environment validator)
- `dynamic-hooks` (10 tools) - AI-powered network hooks
> **💡 Pro Tip**: Use `--minimal` for lightweight deployments or `--disable-*` flags to exclude functionality you don't need!
### Quick Test
Restart your MCP client and ask your agent:
> "Use stealth-browser to navigate to https://example.com and extract the pricing table."
## 🚨 **Common Installation Issues**
**❌ ERROR: Could not find a version that satisfies the requirement [package]**
- **Solution**: Make sure your virtual environment is activated: `venv\Scripts\activate` (Windows) or `source venv/bin/activate` (Mac/Linux)
- **Alternative**: Try upgrading pip first: `pip install --upgrade pip`
**❌ Module not found errors when running server**
- **Solution**: Ensure virtual environment is activated before running
- **Check paths**: Make sure the Claude CLI command uses the correct venv path
**❌ Chrome/Browser issues**
- **Solution**: The server will automatically download Chrome when first run
- **No manual Chrome installation needed**
**❌ "Failed to connect to browser" / Root user issues**
- **Solution**: ✅ **FIXED in v0.2.4!** Auto-detects root/administrator and adds `--no-sandbox` automatically
- **Manual fix**: Add `"args": ["--no-sandbox", "--disable-setuid-sandbox"]` to spawn_browser calls
- **Diagnostic tool**: Use `validate_browser_environment_tool()` to check your environment
**❌ "Input validation error" with args parameter**
- **Solution**: ✅ **FIXED in v0.2.4!** Now accepts both JSON arrays and JSON strings:
- `"args": ["--no-sandbox"]` (preferred)
- `"args": "[\"--no-sandbox\"]"` (also works)
**❌ Container/Docker issues**
- **Solution**: ✅ **FIXED in v0.2.4!** Auto-detects containers and adds required arguments
- **Manual fix**: Add `"args": ["--no-sandbox", "--disable-dev-shm-usage", "--disable-gpu"]`
**❌ "claude mcp add-json" command not found**
- **Solution**: Make sure you have Claude Code CLI installed
- **Alternative**: Use manual configuration method above
**❌ Path errors in Windows**
- **Solution**: Use double backslashes `\\` in JSON strings for Windows paths
- **Example**: `"C:\\\\Users\\\\name\\\\project\\\\venv\\\\Scripts\\\\python.exe"`

## 🎯 **NEW: Advanced Text Input**
**Latest Enhancement (v0.2.3)**: Revolutionary text input capabilities that solve common automation challenges:
### ⚡ **Instant Text Pasting**
```python
# NEW: paste_text() - Lightning-fast text input via CDP
await paste_text(instance_id, "textarea", large_markdown_content, clear_first=True)
```
- **10x faster** than character-by-character typing
- Uses Chrome DevTools Protocol `insert_text` for maximum compatibility
- Perfect for large content (README files, code blocks, forms)
### 📝 **Smart Newline Handling**
```python
# ENHANCED: type_text() with newline parsing
await type_text(instance_id, "textarea", "Line 1\nLine 2\nLine 3", parse_newlines=True, delay_ms=10)
```
- **`parse_newlines=True`**: Converts `\n` to actual Enter key presses
- Essential for multi-line forms, chat apps, and text editors
- Maintains human-like typing with customizable speed
### 🔧 **Why This Matters**
- **Form Automation**: Handle complex multi-line inputs correctly
- **Content Management**: Paste large documents instantly without timeouts
- **Chat Applications**: Send multi-line messages with proper line breaks
- **Code Input**: Paste code snippets with preserved formatting
- **Markdown Editors**: Handle content with proper line separations
**Real-world impact**: What used to take 30+ seconds of character-by-character typing now happens instantly, with proper newline handling for complex forms.
---
## 🛡️ **NEW: Cross-Platform Compatibility & Root Support**
**Latest Enhancement (v0.2.4)**: Automatic platform detection and privilege handling that eliminates common browser spawning issues:
### ⚙️ **Smart Environment Detection**
```python
# NEW: Automatic privilege detection and sandbox handling
validate_browser_environment_tool() # Diagnose your environment
```
- **Root/Administrator Detection**: Auto-adds `--no-sandbox` when running as root
- **Container Detection**: Detects Docker/Kubernetes and adds container-specific args
- **Platform-Aware**: Handles Windows, Linux, macOS differences automatically
- **Chrome Discovery**: Automatically finds Chrome/Chromium installation
### 🔧 **Flexible Args Handling**
```json
// All these formats now work:
{"args": ["--disable-web-security"]} // JSON array
{"args": "[\"--disable-web-security\"]"} // JSON string
{"args": "--disable-web-security"} // Single string
```
- **Multiple Format Support**: Accepts JSON arrays, JSON strings, or single strings
- **Smart Parsing**: Tries JSON first, falls back gracefully
- **Backward Compatible**: Existing configurations continue to work
### 📊 **Built-in Diagnostics**
```bash
# NEW: Environment validation tool
validate_browser_environment_tool()
# Returns: platform info, Chrome path, issues, warnings, recommendations
```
- **Pre-flight Checks**: Validates environment before browser launch
- **Issue Detection**: Identifies common problems and provides solutions
- **Platform Insights**: Detailed system information for debugging
### 🎯 **Why This Matters**
- **Root User Support**: No more "Failed to connect to browser" on Linux servers
- **Container Compatibility**: Works in Docker, Kubernetes, and serverless environments
- **Windows Administrator**: Handles UAC and privilege escalation scenarios
- **Error Prevention**: Catches issues before they cause failures
- **Better Debugging**: Clear diagnostics for troubleshooting
**Real-world impact**: Browser spawning now works reliably across all environments - from local development to production containers to CI/CD pipelines.

# 🔥 **Viral AI Agent Prompts - Copy & Paste to Blow Minds**
*These prompts showcase why this MCP gets 10k+ stars*
---
## 🏆 **The "Impossible" Automations**
### 🛡️ **Bypass Cloudflare Like a Ghost**
```
Use stealth-browser to navigate to a Cloudflare-protected site that blocks all bots. Take a screenshot proving you're accessing the content. Then extract the main content area using extract_complete_element_cdp and show me the HTML structure.
```
*💡 Why this goes viral: Everyone struggles with Cloudflare. This just works.*
### 🏦 **Automate Banking Without Getting Flagged**
```
Use stealth-browser to navigate to [your bank's] login page. Take a screenshot of the login form. Use extract_element_structure to analyze the form fields and security measures. Report what anti-bot protections are visible and how they differ from regular forms.
```
*💡 Why this goes viral: Banks block everyone. This doesn't get detected.*
### 🎯 **Clone Any UI Element Perfectly**
```

Enhanced Element Cloner using proper CDP methods
=================================================
This module provides comprehensive element extraction using the full power of
Chrome DevTools Protocol (CDP) through nodriver. It extracts:
1. Complete computed styles using CDP CSS.getComputedStyleForNode
2. Matched CSS rules using CDP CSS.getMatchedStylesForNode
3. Event listeners using CDP DOMDebugger.getEventListeners
4. All stylesheet information via CDP CSS domain
5. Complete DOM structure and attributes
This provides 100% accurate element cloning by using CDP's native capabilities
instead of limited JavaScript-based extraction.
