What is byob?

byob (Bring Your Own Browser) lets AI agents like Claude or Cursor control your existing open Chrome instance via an MCP server. It exposes 10 tools—read pages, screenshot, click/type elements, grab cookies, navigate tabs, download images, and more—using your real logged-in sessions for sites like GitHub or Gmail. Built in TypeScript with Bun and a Chrome MV3 extension, it runs fully local with a 5-minute install via `byob install` and diagnostics like `byob doctor`.

Why is it gaining traction?

Unlike headless Puppeteer or WebFetch, byob skips cookie copying and bot detection by hijacking your personal browser—no cloud costs, instant auth for Twitter timelines or GitHub curls. The hook is one-prompt web tasks ("read my Gmail unreads" or "screenshot example.com to disk") that just work with your sessions. BYOB meaning "bring your own" echoes bring own phone plans or bring own device setups, making AI web agents feel native.

Who should use this?

AI agent builders needing authenticated web access, like devs prompting Claude to scrape personal dashboards or automate GitHub workflows. Cursor/Cline users tired of fake sessions for real-world tasks (e.g., "google MCP spec and read first result"). Not for production bots—ideal for local prototyping where byob GitHub install shines.

Verdict

Try it for MCP-powered browser agents; v0.1 delivers solid docs, CLI utils, and schemas despite 41 stars and 1.0% credibility score. Early maturity means watch for edge cases like DevTools conflicts, but MIT license and no-phone-home policy make it low-risk for personal use.
