Eliminates the need for headless browser setup or browser automation libraries.

A local MCP server that lets Claude Code and other AI coding tools control the Chrome you already have open — with your logged-in sessions, cookies, and real-browser fingerprint intact, so it sees authenticated pages and passes bot detection. Setup builds a Chrome extension you load unpacked, then registers the MCP server with your AI tools; a curl install script automates the whole flow in about 5 minutes.

Auto-fill and submit web forms using live browser session
Scrape JavaScript-rendered content without headless setup
Test multi-step user workflows directly in Chrome

Why it matters

Eliminates the need for headless browser setup or browser automation libraries. Claude can control your actual Chrome instance, reducing latency and infrastructure overhead.

Things to check

Setup requires loading an unpacked Chrome extension in developer mode and fully quitting/restarting Chrome (Chrome only reads the Native Messaging config at startup). The browser_eval tool is disabled by default (enable with BYOB_ALLOW_EVAL=1). Because the agent drives your real logged-in browser — including session cookies — grant access carefully.
