<summary><b>Background: Why BrowserClaw?</b></summary>

<br/>

Browser automation frameworks that drive a separate browser instance (Playwright, Puppeteer, browser-use) start from a clean profile. They do not inherit your active logins, cookies, or extensions, and copying a live Chrome profile on Windows fails with file-sharing locks. Attaching to an existing Chrome via a debug port triggers security banners.

BrowserClaw takes a different route: a Chrome MV3 extension plus a local Native Messaging bridge, running inside the Chrome you already use. Cookies, sessions, and extensions are preserved, and automation happens in background tabs without stealing focus.

## ⚡ What is BrowserClaw?

BrowserClaw is a Chrome extension + local MCP server that lets AI agents operate your real browser. It exposes 49 tools across 7 categories (navigation, perception, action, observation, management, diagnostics, network), with a minimal 14-tool core profile for everyday sessions.

Two execution paths are available:

1. **Deterministic tools** – indexed clicks, fills, batch pipelines, form wizards, screenshots, network capture, etc. The calling agent plans each step.
2. **`chrome_act_toward_goal`** – a local perception-action micro-loop. The native server perceives the page, decides the next action

Breaking: Browser Use + Jev = Ultrafast ⚡ Findings flights took 7s and cost only $0.0039 🤯 > new action space every step > DOM state space > small LLM fallback to type (this video is at 1x speed btw) Built a tiny open source browser agent. try it below ↓
