🌐 Browser MCP Server

The most comprehensive Browser MCP Server for AI agents — 70 tools with human-like behavior, stealth anti-detection, session reuse, multi-browser support, 50+ device presets, and token-optimized outputs.

Built on Playwright + Model Context Protocol.

✨ Key Features

Feature	Description
🤖 Human-Like Behavior	Bezier curve mouse movements, variable-speed typing, smooth scrolling — evades bot detection
🛡️ Stealth Anti-Detection	WebGL spoofing, canvas fingerprint noise, navigator.webdriver hidden, plugin/language spoofing
🔄 Session Reuse	Connect to existing Chrome via CDP or user-data-dir — keeps cookies, logins, tabs
🌍 Multi-Browser	Chromium, Firefox, WebKit — test across all engines
📱 50+ Device Presets	iPhone, iPad, Pixel, Galaxy, OnePlus, Desktop — full viewport/UA/touch emulation
🌐 Proxy Support	HTTP/HTTPS/SOCKS5 proxy with bypass rules
📊 Network Monitoring	Auto-capture all requests/responses, console logs, filter by type
📸 Visual Annotation	mark_page: numbered boxes on interactive elements — massive token savings
💾 Storage State	Save/load cookies + localStorage for cross-session persistence
🎯 Smart Actions	Natural language commands: "click Login", "type hello into search"
📉 Token Optimized	Compact outputs, configurable truncation — saves 60-80% tokens vs competitors
🎬 Video Recording	Record browser sessions for debugging and replay
📍 Geolocation	Override latitude/longitude for location-based testing
🔒 HTTPS Errors	Ignore certificate errors for internal/staging sites

🚀 Quick Start

Install

git clone https://github.com/user/browser-mcp-server.git
cd browser-mcp-server
npm install
npx playwright install
npm run build

Run

# Auto-detect: tries CDP on port 9222, falls back to launching a new browser
node dist/index.js

# Connect to existing Chrome (preserves your logged-in sessions)
chrome --remote-debugging-port=9222
node dist/index.js --cdp http://localhost:9222

# Reuse Chrome profile (keeps all cookies, logins, extensions)
node dist/index.js --user-data-dir "C:\Users\you\AppData\Local\Google\Chrome\User Data"

# Launch Firefox with iPhone emulation and proxy
node dist/index.js --browser firefox --device "iPhone 15" --proxy-server http://proxy:8080
