⚡ Highlights

• 🥷 Stealth by Default: Uses Camoufox to mask navigator.webdriver, spoof hardware concurrency, randomize canvas/WebGL/audio fingerprints, and bypass anti-bot shields (Cloudflare Turnstile, DataDome, Akamai, etc.).
• 🎭 100% Official Tool Parity: Complete 1:1 drop-in replacement for @playwright/mcp (browser_navigate, browser_click, browser_fill, browser_snapshot, browser_take_screenshot, browser_evaluate, browser_localstorage_*, etc.).
• 🐍 Python-Native Code Generation: Emits clean Python Playwright code snippets instead of JavaScript strings:

  await page.get_by_role("button", name="Submit").click()
  

• 🔄 Dual Engine Flexibility: Run stealth camoufox by default, or switch seamlessly to standard Playwright engines (chromium, chrome, firefox, webkit), remote CDP endpoints, or browser extensions.
• 🚀 Zero-Install with uvx: Run on-demand in Claude Desktop, Cursor, Windsurf, Cline, OpenCode, or any MCP client without manual virtualenv management.

⚔️ Why Camoufox MCP vs Standard Playwright MCP?

When AI agents browse the web using standard automation servers, they are immediately flagged and blocked by Cloudflare Turnstile, DataDome, and anti-bot systems.

Feature / Metric	Camoufox MCP (camoufox-playwright-mcp)	Standard Playwright MCP (@playwright/mcp)
Default Engine	Camoufox Anti-Detect Firefox	Standard Chromium / Firefox
navigator.webdriver	false 🛡️ (Masked)	true 🚨 (Detected)
Bot Detection (bot.sannysoft.com)	PASSED ✅	FAILED ❌
Generated Code Snippets	Python Playwright (await page.click(...))	JavaScript Playwright
Unsafe Code Execution	Python Playwright Async	JavaScript
Hardware Fingerprinting	Spoofed / Humanized	Raw Host Leak
OS / Platform Spoofing	Configurable (Windows / macOS / Linux)	Host Environment
Tool Surface	Full Official Specification	Full Official Specification
Direct Execution	uvx camoufox-playwright-mcp	npx @playwright/mcp

💻 MCP Client Configuration

1. Claude Desktop

Add this to your claude_desktop_config.json:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "camoufox": {
      "command": "uvx",
      "args": [
        "camoufox-playwright-mcp",
        "--headless"
      ]
    }
  }
}

---

2. Cursor (~/.cursor/mcp.json)

Add to your Cursor MCP settings (Cursor Settings > MCP > Add New MCP Server):

{
  "mcpServers": {
    "camoufox": {
      "command": "uvx",
      "args": [
        "camoufox-playwright-mcp",
        "--headless"
      ]
    }
  }
}

---

3. Cline / Roo Code / Windsurf / Zed

{
  "mcpServers": {
    "browser": {
      "command": "uvx",
      "args": [
        "camoufox-playwright-mcp",
        "--headless"
      ]
    }
  }
}

---

4. OpenCode (opencode.json)

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "camoufox": {
      "type": "local",
      "command": ["uvx", "camoufox-playwright-mcp", "--headless"],
      "enabled": true
    }
  }
}

---

🌐 Transports (stdio & Streamable HTTP)

By default, the server uses stdio transport.

Passing --port starts a Streamable HTTP server listening at /mcp:

uvx camoufox-playwright-mcp --headless --host 127.0.0.1 --port 8931

Client configuration for HTTP transport:

{
  "mcpServers": {
    "camoufox": {
      "url": "http://127.0.0.1:8931/mcp"
    }
  }
}

---

🔌 Browser Modes & Connections

1. Persistent Profiles (Default)

By default, the server launches a persistent browser context using an auto-created profile under the user cache directory (~/.cache/camoufox-playwright-mcp/), preserving session state, logins, and cookies across runs:

# Explicit persistent profile directory
uvx camoufox-playwright-mcp --user-data-dir ~/.config/my-browser-profile

2. Isolated Ephemeral Sessions

Use --isolated to run with a temporary, in-memory context that leaves no trace on disk:

uvx camoufox-playwright-mcp --isolated --headless

3. Connect to Existing Browser over CDP

Connect to an existing Chromium / Chrome instance started with --remote-debugging-port=9222:

uvx camoufox-playwright-mcp --cdp-endpoint http://localhost:9222

4. Connect to Bound Playwright Endpoint

Connect to a remote Playwright browser server:

uvx camoufox-playwright-mcp --endpoint ws://localhost:3000

5. Playwright Browser Extension Relay

Attach directly to your existing Chrome or Edge browser tabs via the Playwright Browser Extension:

uvx --from 'camoufox-playwright-mcp[extension]' camoufox-playwright-mcp --extension

---

🥷 Stealth & Anti-Detect Configuration

When running with --browser camoufox (default), Camoufox applies advanced stealth configurations. You can customize anti-detect parameters via a JSON configuration file (--config config.json):

{
  "browser": {
    "provider": "camoufox",
    "camoufoxOptions": {
      "geoip": true,
      "humanize": true,
      "os": "windows",
      "block_images": false,
      "fonts": ["Arial", "Calibri", "Times New Roman"]
    }
  }
}

Key Camoufox Options

Option	Type	Description
geoip	bool	Automatically match timezone, locale, and geolocation to your IP or proxy.
humanize	bool	Add natural, human-like mouse movements and keyboard typing delays.
os	str	Target OS to emulate ("windows", "macos", "linux").
block_images	bool	Block images to optimize network bandwidth and speed up scraping.
webrtc_ip	str	Spoof WebRTC local IP address to prevent real IP leaks.

⚙️ Configuration (JSON & INI)

Configuration is merged with the following precedence (highest priority last):

1. Built-in defaults (browser: camoufox, action timeout: 5000ms, output: file).
2. JSON or INI configuration file (via --config or CAMOUFOX_MCP_CONFIG).
3. Environment variables (CAMOUFOX_MCP_* or PLAYWRIGHT_MCP_*).
4. Explicit CLI arguments.

INI Configuration Example (camoufox.ini)

capabilities = storage,devtools,vision
console.level = info
timeouts.action = 8000
timeouts.navigation = 45000
browser.contextOptions.viewport = 1280x720

Load with:

uvx camoufox-playwright-mcp --config camoufox.ini

---

🌐 Environment Variables

All CLI flags can be set via environment variables:

Variable	Description
CAMOUFOX_MCP_BROWSER	Default browser (camoufox, chrome, chromium, firefox, webkit)
CAMOUFOX_MCP_HEADLESS	Set to true or 1 for headless mode
CAMOUFOX_MCP_ISOLATED	Set to true to use ephemeral isolated contexts
CAMOUFOX_MCP_PROXY_SERVER	Proxy server URL
CAMOUFOX_MCP_CAPS	Comma-separated list of capabilities (storage, devtools, vision, pdf)
CAMOUFOX_MCP_OUTPUT_DIR	Output directory for artifacts (screenshots, downloads)
CAMOUFOX_MCP_CONFIG	Path to JSON/INI configuration file

(Note: PLAYWRIGHT_MCP_* variables are also supported for backward compatibility).

🔬 Intentional Python Divergences & Limitations

This server is designed to follow the official Playwright MCP public contract while providing a Python-native experience:

• Python Code Generation: Upstream @playwright/mcp generates JavaScript snippets; this server generates native Python Playwright snippets (await page.get_by_role(...).click()).
• browser_run_code_unsafe: Executes asynchronous Python Playwright code directly against the active page instance.
• browser.initPage: Accepts Python-native modules defining init_page(page) or default(page).
• browser_annotate: Intentionally omitted (upstream relies on a Node.js dashboard daemon).
• browser_pdf_save: PDF generation is supported when running Headless Chromium engines (--browser chromium --headless).
