🦊 EyeBrowse
A stealthy, LLM-drivable browser engine — one codebase, two faces.
A Python library and an MCP server for driving a real, hard-to-detect browser— Camoufox, a Firefox fork with C++-level fingerprint spoofing — so legitimate automationisn't false-flagged or IP-banned by Cloudflare, DataDome, Akamai, or PerimeterX.

▶ Higher-quality MP4: docs/demo.mp4 — real EyeBrowse captures, composed into an ad by examples/make_demo.py
Why EyeBrowse?
- 🥷 Stealth by default — engine-level fingerprint spoofing (
geoip+humanize+block_webrtcon out of the box);navigator.webdrivermasked; viewport auto-sized to the spoofed screen. Nopuppeteer-extraband-aids — the anti-detection is in the browser. - 🤖 Built for LLMs — pages are read as an ARIA tree with
[ref=…]handles; the model acts by ref (click/type/hover), not by brittle CSS or raw pixels. Cross-origin iframes, shadow DOM, popups — handled. - 🧰 Library and MCP from one codebase — a clean Python API (
EyeBrowse+Session), mirrored 1:1 by a thin MCP server (78browser_*tools) for Claude Code and any MCP client. - 🪟 Never boxed in — the curated high-level API doesn't hide Playwright: reach
session.page/.context/.browserfor anything it doesn't wrap. - 🔋 Batteries included — multi-session, proxy + identity rotation, API-mode captcha solvers, full HAR capture, screen recording (MP4/GIF), and clean-markdown extraction.
Scope. EyeBrowse is a low-level browser engine — it holds no workflow logic.Consumers decide what to do; the engine provides what's possible.

Quickstart
pip install eyebrowse
python -m camoufox fetch # one-time: download the stealth Firefox + GeoIP db
import asyncio
from eyebrowse import EyeBrowse
async def main():
eb = EyeBrowse() # stealth defaults: geoip · humanize · block_webrtc
async with eb.session() as s:
await s.navigate("https://example.com")
print(await s.snapshot()) # ARIA tree with [ref=...] handles
await s.click("e6") # act on a ref from the snapshot
await eb.aclose()
asyncio.run(main())
…or wire it into Claude Code (or any MCP client) — see Use over MCP.
Install
From PyPI
pip install eyebrowse # or: uv pip install eyebrowse
python -m camoufox fetch # one-time browser fetch (like Playwright's `playwright install`)
pip install "eyebrowse[extract]" # optional: + Crawl4AI markdown extraction (heavier)
From source (development)
git clone https://github.com/Evil-Bane/eyebrowse && cd eyebrowse
uv sync # core engine (add --extra extract for Crawl4AI)
uv run python -m camoufox fetch
cp .env.example .env # only if you use a proxy / captcha keys
Python 3.12 (pinned <3.13). Pinned engine: camoufox==0.4.11 (Firefox v135), playwright 1.60, mcp 1.27.
Features
| 🥷 Stealth | Camoufox engine-level fingerprint spoofing; geoip + humanize + block_webrtc by default; webdriver masked; viewport matched to the spoofed screen. |
| 🤖 LLM interaction | aria_snapshot(mode="ai") → ARIA tree + [ref] handles; click / type / hover / select / drag / file-upload / dialogs / keyboard; coordinate mouse too. |
| 🪟 Frames & DOM | cross-origin iframe routing by ref, shadow-DOM piercing, popup/new-tab switching, evaluate inside any frame. |
| 🗂 Multi-session | independent stealth sessions, each with its own context / identity / proxy. |
| 🌐 Network | inspect requests/responses (incl. XHR/fetch bodies & WebSocket frames), block URLs, mock responses, go offline, full HAR export. |
| 💾 State | cookies, localStorage & sessionStorage (CRUD), storage_state save/reload. |
| 🪪 Identity rotation | fresh fingerprint (OS/screen) + isolated profile + paired proxy; pluggable residential ProxyProvider. |
| 🧩 Captcha | pluggable API-mode solvers (CapSolver / 2Captcha / CapMonster / NextCaptcha) + TOTP — no browser extension. |
| 📄 Extraction | Crawl4AI raw: feed → clean, token-efficient markdown (no LLM, no API keys). |
| 🎥 Capture | screenshots, Playwright tracing, and screen recording → MP4 / WebM / GIF (ffmpeg). |
| ✅ Verify & debug | assertions, element highlighting, locator generation, geolocation/header emulation. |

Use as a library
import asyncio
from eyebrowse import EyeBrowse
async def main():
eb = EyeBrowse() # stealth defaults
try:
async with eb.session() as s: # a stealth session (auto-closed)
await s.navigate("https://example.com")
print(await s.snapshot()) # ARIA tree with [ref=...] handles
await s.click("e6") # act on a ref
await s.type("e8", "hello", submit=True)
png = await s.screenshot(full_page=True)
title = await s.page.title() # full Playwright power when you need it
finally:
await eb.aclose()
asyncio.run(main())
Run the included proof: uv run python examples/direct_usage.py.
Use over MCP
EyeBrowse ships an MCP server (eyebrowse-mcp, FastMCP over stdio). Add it to any MCP client.
Claude Code (CLI):
claude mcp add eyebrowse -- eyebrowse-mcp
Any MCP client (JSON config):
{
"mcpServers": {
"eyebrowse": {
"command": "eyebrowse-mcp"
}
}
}
Then drive the loop: browser_navigate(url) → read the snapshot → act by ref(browser_click / browser_type / …). A default session is auto-created, so most tools justwork. Full list: docs/TOOLS.md.
Proxy & identity (optional)
Runs proxyless by default (geoip still aligns locale/timezone to your real IP). Add a proxyonly when you want one:
await eb.new_session(proxy="http://user:[email protected]:8080")
await eb.rotate_identity(proxy="socks5://host:1080") # fresh fingerprint + paired IP
await eb.new_session(no_proxy=True) # force proxyless
Set a default once via EYEBROWSE_PROXY_* in .env, eb.set_static_proxy(...), or a customProxyProvider for rotation. Over MCP: browser_new_session(proxy_url=…) /browser_new_identity(proxy_url=…) / browser_set_proxy(…).
Extraction
eb.extract() (or browser_extract) hands the rendered HTML to Crawl4AI's raw: feed andreturns clean, pruned markdown — no LLM is called and no LLM keys are ever read; theconsuming agent does any structuring.
md = await eb.extract() # markdown string
res = await eb.extract(output_path="data/page.md") # → {"path": ..., "chars": ...}
Recording
Camoufox can't write native browser video, so EyeBrowse rolls its own recorder: it capturesviewport frames and encodes them with ffmpeg into a smooth, real-time MP4/WebM (and apalette-optimized GIF that autoplays inline on GitHub). ffmpeg ships bundled(imageio-ffmpeg), so it works out of the box.
await s.start_recording(fps=30)
# ... drive the browser ...
await s.stop_recording("demo.mp4", extra_paths=["demo.gif"])
The demo at the top was produced this way — see examples/make_demo.py.
How it works
CONSUMERS ENGINE (library: eyebrowse/)
Claude Code ──MCP──▶ mcp/ ──▶ EyeBrowse façade (public API)
your code ─ import ──────────▶ ├─ Camoufox engine (stealth context, HAR)
any MCP client ├─ proxy / identity rotation (pluggable)
├─ captcha solvers (pluggable, API-mode)
└─ Crawl4AI (raw: feed) → clean markdown
The façade (EyeBrowse + Session) is the product; the MCP adapter is a thin 1:1 wrapper overit. The high-level API is curated and LLM-friendly — not a reimplementation of all of Playwright— and the raw page / context / browser objects are always one attribute away.
Camoufox caveats
These shape the API — worth knowing:
evaluateruns in an isolated world — it sees the DOM but not page-scriptwindow.*globals. Read app state via DOM / network / HAR.- reload / back / forward aren't reported by Firefox's Juggler, so they're driven via
goto+an internal navigate() history (they traverse navigate()-driven history, not click-driven). - Not available on Firefox/Camoufox (intentionally omitted, not broken):
page.pdf(), mediaemulation, and native Playwright video — use the ffmpeg recorder instead.
