SuperSurf

SuperSurf gives AI coding agents direct control of your Chrome browser through the Model Context Protocol (MCP). Connect any MCP-compatible assistant — Claude, Cursor, Windsurf — and let it navigate pages, fill forms, capture screenshots, inspect network traffic, and run JavaScript, all through a secure localhost-only WebSocket. No data ever leaves your machine. The extension pairs with a local Node.js server (supersurf-mcp on npm) that handles the MCP handshake and tool routing. Built for developers who want their AI to see and interact with the real web — real cookies, real sessions, real browser profiles. Open source under Apache-2.0. WHY EXTENSION-BASED? Unlike tools that spin up headless browsers, SuperSurf operates inside your real browser profile. Page interaction runs through Chrome's content script isolated world — invisible to page JavaScript. No CDP fingerprints, no VM script artifacts, no detectable automation flags. The extension itself is a human signal to anti-bot systems. 30+ TOOLS INCLUDED - Navigation & tab management - Click, type, hover, scroll, drag, key press - Accessibility tree snapshots & element lookup - Full-page and element screenshots - PDF export - Network request monitoring & inspection - Console message capture - Form filling & secure credential injection - CSS style inspection - JavaScript evaluation - Performance metrics (FCP, LCP, CLS, TTFB) - File downloads - Multi-agent session multiplexing SECURE BY DESIGN - Localhost-only WebSocket — no external connections - Credentials injected extension-side from environment variables — your AI agent never sees raw passwords - Zero runtime dependencies in the extension — browser APIs only - 100% open source — read every line at github.com/LiquidBuiltIt/Supersurf PLATFORM SUPPORT Currently supports macOS and Linux.
