# BrowserMCP
MCP server that gives AI assistants full control over your browser. Works with Claude Code, Cursor, and any MCP-compatible client.
The key advantage: uses your real browser session with all cookies, auth tokens, and extensions — no headless browser, no 403 errors.
## Architecture
```
AI Client (Claude Code) --stdio--> MCP Server (Node.js) --WebSocket--> Chrome Extension
port 12800
```
Three components:
- **MCP Server** — Node.js process, communicates with AI via stdio, bridges to browser via WebSocket
- **WebSocket Bridge** — runs on port 12800, connects server to extension
- **Chrome Extension** — Manifest V3, executes commands in the browser using Chrome APIs
