Chrome Bridge for Claude Code

Bridge your browser to Claude Code: 66 token-efficient web-dev automation tools over a local WebSocket. ChromeOS included.

Chrome Bridge lets Claude Code — Anthropic's CLI coding agent — borrow a tab of the Chrome you are already using, signed in, and hand it back. No headless instance, no debugging port, no cloud service: a local WebSocket (localhost:8765) bridges the Claude Code MCP server on your machine to this extension. What only you can do — a login, a 2FA code, a CAPTCHA, a choice — comes back to you as a banner in the page (the handoff tool): you act, the agent continues. It never types your credentials. Built to be token-efficient: the agent acts on compact element references instead of screenshots, tables are filtered and paginated server-side before they reach the model, and every output is capped — so complex sessions cost far fewer tokens. 60 specialized web-development tools: • Navigation & tabs — open, close, navigate, list tabs; move, tile and lay out windows • DOM — query selectors (shadow-DOM piercing), read pages as markdown, list interactive elements, read a form as filled, modify the DOM • Input — click, type, press keys, fill forms, drag & drop, upload files; hand the browser to the user for 2FA, CAPTCHA or a choice • Screenshots — viewport (one per device preset), element with zoom, full page, visual regression against a baseline, a design mockup or another URL; captures run in the background without stealing window focus • Audits — one call for accessibility, keyboard navigation, SEO, security headers, broken links, web vitals, unused CSS, slow plugins and CDN cache; cookie-consent audit; tracking pixels decoded • Network — monitor requests, mock/block/redirect, record and replay API responses with forced errors, HAR export • Debugging — console logs, with stack traces mapped back to your source files when you log them, JS execution, dev-server error overlays, background page watch • Emulation — media, geolocation, viewport, zoom Cross-platform: Windows, macOS, Linux — any desktop Chrome 135+. Also the only Claude Code browser automation that works on ChromeOS (Crostini). REQUIREMENTS This extension is a companion to the open-source chrome-bridge MCP server and requires it to be installed and configured with Claude Code: https://github.com/frsorrentino/chrome-bridge The execute_js tool additionally requires enabling the "Allow user scripts" toggle in the extension's details page (chrome://extensions). PRIVACY Everything stays on your machine. The extension talks only to localhost — no remote servers, no analytics, no data collection.
