No blocked sites, no filters, no approval pop-ups. Yolo lets Claude work on every website on your real Chrome — free. Yolo Chrome MCP turns your real, logged-in Chrome session into a tool Claude can drive. ══════════════════════════════════════════ QUICK START — 3 steps, about 1 minute ══════════════════════════════════════════ This extension is only HALF of the system. It needs a small helper (the "MCP server") running on your computer so Claude can reach it. You set both up like this: 1. Install this extension (you're almost done — just click "Add"). 2. Open a terminal on your computer and run this one line: npx -y yolo-chrome-mcp@latest install --routing-only (Requires Node.js and Claude Code or Claude Desktop. Don't want to type it? Click this extension's icon — the popup has the exact command with a one-click "Copy" button whenever the dot is red.) 3. Restart Claude Code / Claude Desktop. Click the extension icon — when the status dot turns GREEN, you're connected. Now ask Claude to do something with a tab, e.g. "screenshot this page." That's it. No login, no separate browser, nothing leaves your machine. ────────────────────────────────────────── Requires Node.js + Claude Code (or Claude Desktop). The extension popup also shows the install command with a one-click "Copy" button — open it any time the status dot is red. Pair it with the yolo-chrome-mcp server (npm or Claude Desktop) and Claude can browse, click, type, screenshot, and read the console / network of any tab you already have open — without spawning a separate headless browser, without re-authenticating, and without leaving your computer. It is the lowest-friction way to give Claude an "eyes and hands" on the exact pages you are working with. — Why people switch to it — • Works where official browser tools won't. Many AI browser extensions refuse or block real sites — banking, some Google properties, pages behind strict bot-protection, anything flagged "sensitive." Yolo drives your own already-open tab through the same DevTools Protocol the browser itself uses, so the pages you actually work on just work. No allowlist, no silent refusals. • Token-efficient by design. Claude is told to reach for the cheapest tool first — the page's accessibility tree instead of a screenshot, filtered console/network logs instead of full dumps — so each step spends a fraction of the context a vision-heavy agent burns. Longer tasks before you hit the limit, lower cost per run. • Fast. It acts on the tab you already have open and logged in — no spawning a fresh headless browser, no re-authenticating, no page reloads you didn't ask for. Single tasks like submitting a form or changing a setting land in ~1–2s instead of ~15s+. — What you can do — • "Take a screenshot of my Stripe dashboard and tell me what's wrong" • "Open Linear and triage today's issues for me" • "Read the console errors on this React app and find the cause" • "Fill out this form with my info but stop before submit" • "Compare the Polymarket prices across these 3 tabs" • "Open Gmail and summarize the last 10 unread threads" — How it works — 1. Install this Chrome extension. It connects to a local WebSocket on your computer (127.0.0.1, no external traffic). 2. Run the one-line install command shown above. It registers the MCP server with Claude (`claude mcp add`) and installs the routing hook + CLAUDE.md rule so Claude always picks Yolo when it needs a browser. 3. Restart Claude Code / Claude Desktop. The extension popup's dot turns green once Claude spawns the server. 4. Ask Claude to do something with a tab. Claude calls the server, the server forwards the call to this extension, the extension acts on your Chrome tab using DevTools Protocol, and the result comes back to Claude. — 19 tools, lean by default — listTabs · getTabInfo · screenshot · getPageText · getInteractables · click · type · scroll · navigate · createTab · closeTab · evalJs · waitForStable · getConsoleLogs · getNetworkActivity · getNetworkRequest · getStorage · getSourceAt · setSafetyMode Designed so Claude picks the cheapest tool for the job (accessibility tree over screenshots, filtered logs over full dumps), keeping the conversation context small. — Safety overlay — A locally-rendered confirmation banner asks before potentially-sensitive actions: payment / purchase labels, account deletion, password-form submits, credit-card / password input, and risky JavaScript that touches cookies / fetch / localStorage. Navigation and ordinary clicks pass through without prompts. Configurable via the popup. — Multi-session safe — Multiple concurrent Claude Code sessions on the same machine share one extension via a primary/secondary MCP architecture. No port conflicts, no "Failed to connect" surprises. — What this extension does NOT do — • It does not transmit data to any third-party server. Everything goes through 127.0.0.1 only. • It does not read tabs in the background without an explicit AI request. • It does not contain analytics or telemetry. — Open source — Source: https://github.com/rikutoe/yolo-chrome-mcp License: MIT Bugs / requests: https://github.com/rikutoe/yolo-chrome-mcp/issues Privacy policy: https://seedx.tech/privacy
