MCP Camoufox

The most feature-rich stealth browser MCP server. 102 tools for full browser control powered by Camoufox — a Firefox fork with C++ level anti-detection that bypasses Cloudflare, bot detection, and anti-automation.

One command. No Python. No manual setup. Everything auto-installs.

claude mcp add camoufox -- npx -y mcp-camoufox@latest

What Can It Do?

• Login to Google, ChatGPT, GitHub — without getting blocked
• Fill forms, click buttons, type text, upload files
• Manage cookies, localStorage, sessions across visits
• Take screenshots, export PDFs, capture network traffic
• Work with multiple tabs, iframes, dialogs
• Execute JavaScript, inspect elements, scroll pages
• Scrape structured data (job listings, products) with auto-detected selectors
• All while being undetectable by anti-bot systems

Comparison

Proven on Real Sites

🎯 Cloudflare Turnstile → Success via click_turnstile()

click_turnstile() auto-detects the widget via 6 selector fallback (iframe[src*=challenges.cloudflare.com], [data-sitekey], .cf-turnstile, …), computes checkbox position (offset_x=30 from widget left), and clicks with a 3-step Bezier-like approach — combined with Camoufox's native humanize + disable_coop for cross-origin iframe click.

Scope: works on Interactive Turnstile (visible iframe widget). Managed Challenge interstitials ("Just a moment...") render the widget in shadow DOM — not supported here; use sister project mcp-stealth-chrome (Chrome+CDP) for those. Real-world bypass success also depends on IP reputation and browser fingerprint — code alone doesn't guarantee it.

🧪 bot.sannysoft.com → Firefox Fingerprint Pass

User Agent reports Firefox/135.0, WebDriver missing, WebDriver Advanced passed, Permissions prompt, Plugins length 5 passed, Languages en-US,en, WebGL Intel HD Graphics — all green. ("Chrome: missing" is expected — Camoufox spoofs Firefox, not Chrome.)

🔍 browserscan.net/bot-detection → All Categories Normal

WebDriver, User-Agent, CDP, Navigator — every detection category returns "Normal". Camoufox's C++-level Firefox patches leave zero automation signals.

Examples

Login to a website

browser_launch(url="https://accounts.google.com", headless=false)
browser_snapshot()                              # see email input
fill(ref="e1", value="[email protected]")          # fill email
click(ref="e4")                                 # click Next
wait_for(selector='input[type="password"]')     # wait for password page
browser_snapshot()
fill(ref="e2", value="mypassword")              # fill password
click(ref="e4")                                 # click Next

Fill a form in one call

fill_form(
  fields=[
    {ref: "e3", value: "John Doe"},
    {ref: "e5", value: "[email protected]"},
    {ref: "e7", value: "Hello world"}
  ],
  submit_ref="e10"
)

Batch multiple actions

batch_actions(actions=[
  {type: "click", ref: "e5"},
  {type: "wait", timeout: 1000},
  {type: "fill", ref: "e8", value: "search query"},
  {type: "press", key: "Enter"}
])

Search Google

browser_launch(url="https://google.com")
browser_snapshot()
click(ref="e5")                               # search box
type_text(text="mcp-camoufox npm")
press_key(key="Enter")

Multi-tab research

browser_launch(url="https://github.com")
tab_new(url="https://stackoverflow.com")
tab_list()
tab_select(index=0)

Wait for API response

click(ref="e10")
wait_for_response(url_pattern="/api/data")
browser_snapshot()

Inspect elements

inspect_element(ref="e5")
get_links(filter="github.com")
query_selector_all(selector=".product-card")

Work with iframes

list_frames()
frame_evaluate(frame_index=1, expression="document.title")

Scrape job listings (structured)

browser_launch(url="https://glints.com/id/opportunities/jobs/explore")
detect_content_pattern()                      # auto-suggest selectors
extract_structured(
  container_selector=".job-card",             # from detect_content_pattern
  fields=[
    {name: "title", selector: "h3"},
    {name: "company", selector: ".company-name"},
    {name: "location", selector: ".location"},
    {name: "url", selector: "a", attribute: "href"}
  ]
)

Scrape page content (smart)

scrape_page(only_main_content=true, max_text_length=8000)
# Returns: title, url, meta, text (truncated at paragraph boundary),
#          links, headings, truncated flag, total_text_length

Manage storage

localstorage_get()
localstorage_set(key="token", value="abc123")
cookie_list(domain="example.com")

How It Works

AI Agent (Claude, Cursor, Windsurf, VS Code)
    |
    |  MCP Protocol (stdio JSON-RPC)
    v
mcp-camoufox (Node.js)
    |
    |  Playwright API (Juggler protocol, NOT CDP)
    v
Camoufox (Patched Firefox binary)
    |
    |  C++ anti-fingerprint patches
    v
Website (Cloudflare, bot detection — bypassed)

Why stealth works

• Juggler protocol instead of CDP — sites detecting Chrome DevTools Protocol cannot detect Camoufox
• C++ level patches — fingerprint spoofing at browser engine level, not JavaScript injection
• GeoIP auto-detection — timezone, locale, geolocation match your real IP
• Human-like behavior — optional humanize mode for realistic mouse movements

Why sessions persist

Browser profile stored at ~/.camoufox-mcp/profile/. Cookies, localStorage, IndexedDB survive across sessions. Login once, stay logged in.

Why refs work better

browser_snapshot tags elements with data-mcp-ref attributes. This is:

• More token-efficient than sending full HTML
• More reliable than CSS selectors that break when sites update
• Clickable via click(ref="e5") — no selector gymnastics

Data Storage

Reset everything: rm -rf ~/.camoufox-mcp/ — or call the reset_profile tool (browser must be closed first).

Switching between accounts on the same domain

The default profile persists across browser_close calls, so the next login on the same domain inherits cookies + session — sometimes redirecting to the wrong account. Two options:

• browser_launch(fresh_profile=true) — uses a temp profile dir that's removed on browser_close. Best for one-off logins.
• reset_profile (browser must be closed) — wipes the shared profile entirely.
