AlienMcp - Browser Automation for AI

Let your local AI assistant drive your browser: read pages, click, fill forms, screenshot. Runs entirely on your machine.

AlienMcp connects AI agents (Claude Code, Cursor, VS Code) to your real Chrome browser via the Model Context Protocol (MCP). Unlike headless browser automation, AlienMcp controls your actual tabs — with your logged-in sessions, cookies, and extensions intact. 20 MCP Tools: • Screenshot (viewport & full page) • Navigate, click, type, hover, scroll • Wait for elements (SPA-friendly) • Read page content (HTML/text) • Find elements (CSS, XPath, text, ARIA) • Fill forms (React/Vue/Angular compatible) • Execute JavaScript (bypasses CSP via CDP) • Modify DOM (attributes, styles, text) • Monitor network requests & console • Manage cookies & localStorage • Generate PDF • Emulate devices, network, geolocation, CPU throttling Key Features: • Tab Group scoping — choose which tabs the AI can access • Trusted keyboard & mouse events via Chrome DevTools Protocol • 100% local — no data sent to external servers • Works with any MCP-compatible AI client How it works: 1. Install the extension 2. Add the MCP server to your AI client 3. Add tabs to the AlienMcp group 4. Let your AI agent control the browser Open source: https://www.alien-mcp.com
