Stealth fork of [agent-browser](https://github.com/vercel-labs/agent-browser) — connects to your real Chrome, shares your login sessions, and is undetectable by anti-bot systems.
|
||||
|
||||
For basic usage, commands, and API reference, see the [upstream documentation](https://github.com/vercel-labs/agent-browser).
|
||||
|
||||
## Give your AI agent the browser you already live in
|
||||
|
||||
**No fresh Chrome. No re-login. No "are you a robot?" walls.**
|
||||
|
||||
agent-browser-stealth points **any** agent — Claude Code, Cursor, Codex, your own scripts — at the **Chrome you're already signed into everything on**. It clicks in *your* window, so you watch it work and grab the wheel the moment it hits a 2FA prompt or captcha. And because it's literally your real browser (over a one-click extension, native messaging — no debug port), sites read it as 100% human: **[CreepJS scores it 0% bot](#anti-detection).**
|
||||
|
||||
**Why not just use…**
|
||||
|
||||
- **Playwright / Puppeteer / browser-use?** They boot an *empty* browser — so you redo every login, fight every captcha, and still get flagged as automation. We use the session you already have.
|
||||
- **Claude's Chrome extension?** Great, but it only drives Claude. This drives *any* agent or CLI.
|
||||
- **A raw `--remote-debugging-port`** (web-access, etc.)? Chrome 136+ pops **"Allow remote debugging?"** on *every* connect. This never does — one-click Store extension, native messaging.

## Setup: connect to your Chrome
|
||||
|
||||
Attaching uses the Chrome DevTools Protocol, which Chrome only exposes when it is
|
||||
**launched with a remote-debugging port**. This is a startup flag, not a setting
|
||||
— the `chrome://inspect` toggle alone is **not** enough (it only enables target
|
||||
discovery, not the CDP attach).
|
||||
**Recommended — the browser extension (one click, no popups).** Install the
|
||||
[**agent-browser-stealth** extension from the Chrome Web Store](https://chromewebstore.google.com/detail/agent-browser-stealth/knfcmbamhjmaonkfnjhldjedeobeafmk),
|
||||
then register the local bridge once:
|
||||
|
||||
**Recommended — fully quit Chrome, then relaunch with the port:**
|
||||
```bash
|
||||
agent-browser extension install # register the native-messaging host (one-time)
|
||||
agent-browser open https://x.com/home
|
||||
```
|
||||
|
||||
`agent-browser open` then drives your real, logged-in Chrome over **native
|
||||
messaging** — no debug port, no token, and **no "Allow remote debugging?" dialog,
|
||||
ever**. The extension auto-updates and survives Chrome restarts, so it stays
|
||||
connected with zero per-use confirmation (ideal for unattended/agent use).

## 把你**已经登录好**的浏览器,交给你的 AI agent
|
||||
|
||||
**不用开新 Chrome。不用重新登录。不用跟"你是不是机器人"较劲。**
|
||||
|
||||
agent-browser-stealth 让**任意** agent(Claude Code、Cursor、Codex、你自己的脚本)直接操作你**已经登录了所有网站**的那个 Chrome。它在**你的窗口里**点击,你看着它干活,撞到 2FA / 验证码的瞬间你接管一下,它接着跑。因为它**就是你的真实浏览器**(一键装的扩展、原生消息、无调试端口),网站眼里它 100% 是人:**[CreepJS 实测 0% 机器人](#反检测)。**
|
||||
|
||||
**为什么不用……**
|
||||
|
||||
- **Playwright / Puppeteer / browser-use?** 它们开的是**空**浏览器 —— 每个登录你重做、每个验证码你硬扛、最后还被标成自动化。我们直接用你**现成的**会话。
|
||||
- **Claude 的 Chrome 插件?** 很好,但**只能给 Claude 用**。我们给**任意** agent / CLI 用。
|
||||
- **裸 `--remote-debugging-port`**(web-access 等)? Chrome 136+ **每次连都弹** "Allow remote debugging?"。我们**永不弹** —— 商店一键装,原生消息。

|

|
||||
## 工作原理
|
||||
|
||||

|
||||
|
||||
你的 **agent-browser CLI** 通过 Chrome **原生消息(native messaging)** 和一个小**浏览器扩展**通信 —— 这是本机进程间通道,**无网络端口、无 token、无远程服务器**。扩展用 `chrome.debugger` 驱动你指定的标签页(在你**已登录**的 Chrome 里),再把结果交还给 CLI。全程都在你本机。
|
||||
|
||||

|
||||
|
||||
每个 `--session` 拿到**自己的彩色标签组**,多个 agent 共用同一个真实浏览器、互不干扰,也不动你自己的标签页。
|
||||
|
||||
## 安装
|
||||
|
||||
```bash
|
||||
curl -fsSL https://raw.githubusercontent.com/leeguooooo/agent-browser-stealth/main/install.sh | sh
|
||||
```
|
||||
|
||||
从最新的 [GitHub Release](https://github.com/leeguooooo/agent-browser-stealth/releases) 下载对应平台的预编译二进制,安装 `agent-browser`(以及 `abs` 别名)。无需 npm,无需 token。
|
||||
|
||||
### 安装 AI agent skills
|
||||
|
||||
```bash
|
||||
npx skills add leeguooooo/agent-browser-stealth
|
||||
```
|
||||
|
||||
把 `skills/agent-browser` 拉进当前项目,让你的 AI agent 拿到正确的用法和预授权的 bash 权限。
|
||||
|
||||
## 连接你的 Chrome
|
||||
|
||||
**推荐 —— 浏览器扩展(一键,无弹窗)。** 从 Chrome 应用商店安装 [**agent-browser-stealth** 扩展](https://chromewebstore.google.com/detail/agent-browser-stealth/knfcmbamhjmaonkfnjhldjedeobeafmk),再注册一次本地桥:
|
||||
|
||||
```bash
|
||||
agent-browser extension install # 注册原生消息 host(一次性)
|
||||
agent-browser open https://x.com/home
|
||||
```
|
||||
|
||||
之后 `agent-browser open` 就通过**原生消息**驱动你真实、已登录的 Chrome —— 无调试端口、无 token、**永远不弹 "Allow remote debugging?"**。扩展自动更新、重启不掉,零确认(适合无人值守 / agent 场景)。
|
||||
|
||||
<details>
|
||||
<summary>备选 —— 裸 remote-debugging 端口(会弹同意框)</summary>
|
||||
|
||||
不装扩展时,agent-browser 退回用 CDP 连接,而 Chrome 只在带 remote-debugging 端口启动时才暴露它:
|
||||
|
||||
```bash
|
||||
# macOS
|
||||
open -a "Google Chrome" --args --remote-debugging-port=9222
|
||||
# Linux
|
||||
google-chrome --remote-debugging-port=9222
|
||||
# Windows: 给 Chrome 快捷方式 target 加 --remote-debugging-port=9222
|
||||
```
|
||||
|
||||
然后 `agent-browser open <url>` 自动发现端口。首次连接 **Chrome 136+ 会弹 "Allow remote debugging?"** —— 点一次 Allow(该 Chrome 会话内持续有效)。上面的扩展则完全避开这个框。
|
||||
</details>
|
||||
|
||||
## 用法
|
||||
|
||||
```bash
|
||||
# 连接你的 Chrome 并导航
|
||||
agent-browser open https://example.com
|
||||
|
||||
# 一切都在你已登录的浏览器里进行
|
||||
agent-browser click "Post"
|
||||
agent-browser fill "Title" "Hello World"
|
||||
agent-browser screenshot ./page.png
|
||||
```
|
||||
|
||||
Agent 在你的 Chrome 里操作 —— 你能实时看到开标签、加载、点击。任意时刻都能接管(比如手动过验证码),然后让 agent 继续。
|
||||
|
||||
### 独立模式(`--launch`)
|
||||
|
||||
```bash
|
||||
# 临时:全新空 profile —— 无 cookie 无登录(适合 CI / 测试)
|
||||
agent-browser --launch open https://example.com
|
||||
|
||||
# 保留登录:用你真实的 Chrome profile 启动
|
||||
agent-browser --launch --profile auto open https://x.com/home
|
||||
```
|
||||
|
||||
## 反检测
|
||||
|
||||
连接你真实 Chrome 时,我们**零** JS 注入 —— 浏览器指纹完全是真的。指导原则是 **native CDP/Chrome 覆盖优先于 JS 谎言**:被重定义的 getter 本身可被检测,原生覆盖则不会。
|
||||
|
||||
- `navigator.webdriver = false` 走 `Emulation.setAutomationOverride`(原生,CreepJS 类说谎检测查不出)。
|
||||
- **`Runtime.enable` 默认关闭** —— 活着的 `Runtime` 域是可被检测的 CDP 信号(patchright/rebrowser 的 "runtime leak"),即便连的是你真实 Chrome。只在你主动开启 console/错误捕获时才启用。
|
||||
|
||||
**实测结果(连接真实 Chrome,中继路径):**
|
||||
|
||||
| 检测站 | 结果 |
|
||||
|---|---|
|
||||
| [CreepJS](https://abrahamjuliot.github.io/creepjs/) | **0% stealth · 0% headless**(零 override 痕迹) |
|
||||
| [bot.incolumitas.com](https://bot.incolumitas.com/) | 全部 OK(overflowTest / overrideTest / puppeteerExtraStealth / worker 一致性) |
|
||||
| [rebrowser-bot-detector](https://bot-detector.rebrowser.net/) | `runtimeEnableLeak` 🟢 · `pwInitScripts` 🟢 |
|
||||
| [bot.sannysoft.com](https://bot.sannysoft.com) | 全绿 |
|
||||
|
||||
`--launch` 独立模式下会改用一整套隐身补丁,同样过上述检测。
|
||||
|
||||
## 与上游的差异
|
||||
|
||||
基于 [agent-browser v0.27.0](https://github.com/vercel-labs/agent-browser):
|
||||
|
||||
- **默认 auto-connect** —— `agent-browser open` 连你的 Chrome 而非启新的
|
||||
- **CDP 原生隐身** —— `Emulation.setAutomationOverride` 而非 JS 补丁
|
||||
- **双隐身模式** —— 真实 Chrome 零补丁,`--launch` 全补丁
|
||||
- **`--launch` / `--new`** —— 显式启动独立浏览器
|
||||
- **CI 自动检测** —— 设了 `CI` 环境变量时走独立模式
|
||||
|
||||
所有上游功能(命令、快照、截图、录制、标签、会话等)保持一致。
