DOMShell — Browser Filesystem for AI Agents

DOMShell turns your browser into a filesystem. Navigate Chrome with Linux commands - ls, cd, grep, cat, click - through a terminal in the Side Panel. AI agents (Claude, GPT, LLMs) control the browser through one MCP tool - domshell_execute - that exposes the full command vocabulary over the Model Context Protocol. No screenshots, no pixel coordinates, no brittle CSS selectors. Just clean, deterministic commands. HOW IT WORKS DOMShell maps the browser's Accessibility Tree into a virtual filesystem: - Windows and tabs become top-level directories (~) - Page sections become nested directories - Buttons, links, inputs become files you can click, read, and interact with Navigate a website the same way you'd navigate /usr/local/bin. KEY FEATURES Terminal Interface - A full terminal in Chrome's Side Panel with 39 commands: ls, cd, cat, grep, find, click, type, submit, scroll, and more. AI Agent Integration - Connects to Claude Desktop, Cursor, Windsurf, or any MCP-compatible client via the Model Context Protocol. Your AI agent browses the web using familiar shell commands. Multiple agents can connect simultaneously — each gets its own isolated Chrome tab-group lane, so they never collide. Multi-Tab Orchestration - Run commands across multiple open tabs simultaneously with each. Open N URLs in a single call with for. Save and replay workflows with script. JavaScript Execution - Run arbitrary JS with eval, discover page APIs with functions, invoke them with call, and detect changes with watch. Batch Scripting - Save reusable command sequences with script save, then replay across multiple inputs with for iteration. USE CASES - AI-powered web scraping and data extraction - Automated testing and QA workflows - Accessibility auditing - Browser automation without Selenium or Puppeteer - Research pipelines that extract from multiple pages - Building MCP-powered AI agents that browse the web FOR DEVELOPERS DOMShell exposes a WebSocket API (localhost:9876) and an HTTP MCP server (localhost:3001). Integrate with any language or framework. Works with: Claude Desktop, Claude Code, Cursor, Windsurf, Cline, and any MCP-compatible AI client.
