Turn any JS function into a tool your AI can call

Write a short JavaScript function, izan.io turns it into an MCP tool. Claude Code, Cursor, VS Code - any MCP client calls it and gets the result. 500+ community tools included, or write your own in minutes.


AI wastes time figuring out browsers

Ask an AI to check your Amazon orders and watch it struggle. It guesses selectors, gets lost in popups, retries five times, and still fails. So you look for an API - if one even exists, it costs money, needs an API key, has rate limits, and returns half the data you actually need. Meanwhile the data is right there on the screen. You just need a 20-line JS tool to grab it. izan.io lets you write that tool once and call it forever.


How it works

1

Install the Chrome extension

Get izan.io from the Chrome Web Store. One click, no config. The extension runs an MCP server inside your browser.

2

Add one line to your AI tool

Add the config below to Claude Desktop, Claude Code, Cursor, VS Code, or any MCP client. The bridge starts automatically.

Claude Desktop / Claude Code / Cursor / VS Code
{
  "mcpServers": {
    "izan-browser": {
      "command": "npx",
      "args": ["izan-mcp"]
    }
  }
}

AI calls tools, gets results

Your AI calls pre-built tools like amazon_search or gmail_read_inbox. Each tool knows exactly what to do - no page inspection, no guessing selectors. Fast, reliable, back-to-back.


Why izan.io

No inference overhead

Tools handle all the browser logic - clicking, waiting, scrolling, extracting. The AI just calls a function and gets structured data back. No wasted tokens figuring out selectors.

500+ ready-made tools

Amazon, Gmail, LinkedIn, GitHub, YouTube and 80+ more sites covered. Install from the marketplace, or write your own with the built-in editor.
