A Model Context Protocol (MCP) server that provides browser automation tools powered by Camoufox — a stealthy, anti-detect browser built on Firefox. It exposes a Playwright-MCP compatible tool interface using accessibility snapshots and ref-based element targeting.

Think of it as playwright-mcp, but with built-in anti-detection and fingerprint spoofing.

Features

Anti-detect browser fingerprinting — Camoufox automatically spoofs browser fingerprints to bypass bot detection
Ref-based accessibility snapshots — Interact with page elements via accessibility refs, no CSS selectors needed
Human-like cursor movement — Cursor humanization enabled by default for realistic interactions
WebRTC leak protection — WebRTC blocked by default to prevent IP leaks
Isolated browser profiles by default — Each server process gets a fresh temporary profile that is deleted on close; pass --user-data-dir to reuse a persistent profile
GeoIP auto-matching — Automatically match browser locale/timezone to proxy location
Proxy support — Full proxy support including authentication
WebGL fingerprint control — Specify WebGL vendor/renderer pair or block entirely
Custom addons — Load custom Firefox addons or exclude defaults like uBlock Origin
Advanced fingerprint config — Override any BrowserForge fingerprint property or use a custom fingerprint
Firefox preferences — Set custom Firefox user preferences
Browser caching — Optional page/request caching for performance
Privacy controls — Block WebGL and image loading to reduce leaks and bandwidth
Multi-tab management — Create, close, select, and list browser tabs
Modal & dialog handling — Handle JavaScript dialogs and file choosers
Console & network monitoring — Inspect console messages and network requests

Quick Start

Use with Claude Desktop

Add to your Claude Desktop configuration (claude_desktop_config.json):

{
  "mcpServers": {
    "camoufox": {

Add to .vscode/mcp.json:

{
  "servers": {
    "camoufox": {
      "command": "uvx",
      "args": ["camoufox-mcp-python"]
    }
  }
}

Use with Codex CLI

Add to codex.json or pass via CLI:

codex --mcp-server "npx @anthropic-ai/mcp-proxy -- uvx camoufox-mcp-python"

Pin a specific version

{
  "mcpServers": {
    "camoufox": {
      "command": "uvx",
      "args": ["--from", "camoufox-mcp-python==0.2.1", "camoufox-mcp-python"]
    }
  }
}

CLI Options

| Option | Description | |---|---| | --headless / --no-headless | Run the browser headlessly (default: on) | | --proxy <url> | Proxy server URL (supports user:pass@host:port) | | --os <os> | Target OS fingerprint: windows, macos, linux (repeatable) | | --humanize [seconds] | Cursor humanization (default: on). Pass a number for max duration, or false to disable | | --geoip [ip] | Auto-match locale/timezone to proxy IP, or specify a target IP | | --locale <locale> | Browser locale(s), e.g. en-US (repeatable, comma-separated) | | --window <WxH> | Outer window size, e.g. 1280x720 | | --block-webrtc / --no-block-webrtc | Block WebRTC to prevent IP leaks (default: on) | | --block-webgl | Disable WebGL | | --block-images | Block image requests to reduce bandwidth | | --disable-coop | Disable COOP for cross-origin iframe interactions | | --user-data-dir <path> | Optional persistent profile directory. If omitted, each server process uses an isolated temporary profile that is deleted on close | | --caps <groups> | Enable capability groups, e.g. dangerous (enables browser_evaluate) | | --webgl-config <v,r> | WebGL vendor/renderer pair, e.g. "Intel Inc.,Intel(R) UHD Graphics 620" | | --addons <paths> | Paths to extracted Firefox addons (repeatable, comma-separated) | | --exclude-addons <names> | Default addons to exclude, e.g. UBO (repeatable, comma-separated) | | --config <json> | Camoufox fingerprint properties as a JSON string | | --enable-cache | Cache previous pages and requests (uses more memory) | | --firefox-user-prefs <json> | Firefox user preferences as a JSON string | | --i-know-what-im-doing | Silence Camoufox warnings for advanced configurations | | --debug | Print the config being sent to Camoufox |

Examples

# Zero-config anti-detection (headless + humanize + block-webrtc on by default)
camoufox-mcp-python

# With proxy and GeoIP matching
camoufox-mcp-python --proxy http://user:pass@proxy.example.com:8080 --geoip

# Visible browser for debugging
camoufox-mcp-python --no-headless --debug

# Custom WebGL fingerprint
camoufox-mcp-python --webgl-config "Intel Inc.,Intel(R) UHD Graphics 620" --os windows

# Custom fingerprint properties
camoufox-mcp-python --config '{"navigator.hardwareConcurrency": 8}'

# With caching and custom Firefox prefs
camoufox-mcp-python --enable-cache --firefox-user-prefs '{"dom.webnotifications.enabled": false}'

# Privacy-hardened mode
camoufox-mcp-python --block-webgl --block-images

# Disable default anti-detection for debugging
camoufox-mcp-python --no-headless --humanize false --no-block-webrtc --debug

# Enable JavaScript evaluation
camoufox-mcp-python --caps dangerous

How It Works

The server uses Camoufox (a Firefox-based anti-detect browser) through Playwright's async API. Pages are represented as accessibility snapshots in YAML format, where each interactive element is assigned a ref identifier. The AI model reads the snapshot, identifies the target ref, and calls the appropriate tool — no fragile CSS/XPath selectors required.
