Browser Without Bloat — 30KB MCP Browser Automation Server

npm version npm downloads GitHub License Size

No Playwright. No Puppeteer. No 400MB downloads. Just raw Chrome DevTools Protocol.

bwb gives any AI agent (Claude Code, OpenCode, Cline, Antigravity, Cursor, Continue, etc.) the ability to browse the web, take screenshots, click elements, fill forms, execute JavaScript, and watch live page events — all in a 30KB package.

Created by Krish Tiwari (@krshforever).

🚀 The Breakthrough: Watch Your Pages Live

bwb is the first and only MCP browser tool that captures live page events.

    Agent->>bwb: browser_watch({action:"start", events:["all"]})
    bwb->>Page: 🎬 Recording console, network, errors...
    Agent->>bwb: browser_goto({url:"https://example.com"})
    bwb->>Page: Navigate, interact...
    Page-->>bwb: ⚡ Console.log, Network request, JS Error
    Agent->>bwb: browser_watch({action:"poll"})
    bwb-->>Agent: [{console:"React mounted"}, {network:"GET /api/data 200"}, ...]
    Agent->>bwb: browser_watch({action:"stop"})
    bwb-->>Agent: ✅ Recording stopped, 47 events captured

No other MCP browser tool does this. Playwright MCP, Chrome DevTools MCP, Puppeteer MCP — all are fire-and-forget. bwb is the black box recorder for browser automation.

Your agent can now:

Debug SPAs — see React/Vue/Angular errors in real-time
Track API calls — every network request, response, and status code
Detect loading states — know when the page is actually done rendering
Intercept console output — catch warnings, logs, and errors as they happen

🛠 Prerequisites

Just Chrome or Chromium installed anywhere on your system. bwb auto-detects it.

Platform	Install
Termux/Android	`pkg install chromium`
Linux (Debian/Ubuntu)	`sudo apt install chromium-browser`
macOS	`brew install --cask google-chrome`
Windows	Download from google.com/chrome
CI/Docker	`apt-get install -y chromium`

📋 Configuration

CLI flag	Env var	Default	Description
`--browser-path`	`BWB_CHROME_PATH`	auto-detected	Path to Chrome/Chromium binary
`--port`	`BWB_CDP_PORT`	`0` (random free port)	Remote debugging port
`--user-data-dir`	`BWB_USER_DATA_DIR`	`~/.cache/bwb-browser`	Browser profile directory
`--headless`	`BWB_HEADLESS`	`true`	Run headless (`true`/`false`)
`--screenshots-dir`	`BWB_SCREENSHOTS_DIR`	`~/bwb-screenshots/`	Screenshot save location
`--timeout`	`BWB_NAV_TIMEOUT`	`30000`	Navigation timeout in ms

Note: On Android/Termux, screenshots default to /storage/emulated/0/Download/bwb-screenshots/ so they're accessible from any file manager or gallery app.

🤖 Compatible AI Agents

bwb works with every major AI coding agent via MCP:

Agent	Config File
Claude Code	`~/.claude/settings.json`
OpenCode	`~/.config/opencode/opencode.json`
Antigravity CLI	`~/.gemini/antigravity-cli/mcp_config.json`
Cline (VS Code)	`~/.cline/mcp.json`
Continue.dev	`~/.continue/config.json`
Cursor	`.cursor/mcp.json`

Cody (Sourcegraph)	MCP config
Windsurf	MCP config

🎯 Give this to any AI agent to auto-install bwb: See the copy-paste prompt in AGENTS.md

🔥 Using `browser_watch` (The Game Changer)

Start watching:

browser_watch({action: "start", events: ["all"]})

Browse around:

browser_goto({url: "https://example.com"})
browser_click({selector: "button"})

See everything that happened:

browser_watch({action: "poll"})
# → [{console: "App initialized"}, {network: "GET /api/data 200"}, ...]

Stop recording:

browser_watch({action: "stop"})

The agent gets structured event data — not just screenshots. It can SEE what the page is doing internally.

🌍 Platform Support

Linux	✅	Works with any Chrome/Chromium
macOS	✅	Google Chrome auto-detected
