MCPMonkey
AI Agent Browser Extension
What is MCPMonkey?
MCPMonkey is a fork of Violentmonkey, extending its powerful userscript capabilities to support Model Context Protocol (MCP) servers. This project bridges the gap between AI language models and browser interactions.
Quick Start
- Add
npx mcpmonkey-server
to Cursor (Settings > Features > MCP Servers) - Install the Firefox browser extension
- Click here to install the page style extractor userscript
Try it: Browse to a website and ask Cursor: "get the page styles and apply it to my project"
Key Features
- Tab Management: Get information about open tabs, create new tabs, close tabs, activate tabs, and duplicate tabs
- Page Style Extraction: Extract styling information from web pages for AI analysis with structured JSON data
- User Script Support: Full compatibility with existing userscripts (inherited from Violentmonkey)
- Cursor Integration: Full support for Cursor's MCP integration (v0.45.7+)
Coming Soon
One of our most exciting planned features is Custom MCP Scripts. These special.mcp.js
files will let you create website-specific tools that AI assistants can use to interact directly with web applications. Imagine giving your AI assistant custom abilities for your favorite websites - from filling forms to extracting data or navigating complex interfaces!
