Select context for coding agents directly from your website
How? Point at any element and press ⌘C (Mac) or Ctrl+C (Windows/Linux) to copy the file name, React component, and HTML source code.
It makes tools like Cursor, Claude Code, Copilot run up to 3× faster and more accurate.
Run this command at your project root (where next.config.ts or vite.config.ts is located):
npx -y grab@latest initUse the -y flag to skip interactive prompts:
npx -y grab@latest init -yConnect React Grab directly to your coding agent (Cursor, Claude Code, Codex, Gemini, Amp, and more):
npx -y grab@latest add [agent]Or connect via MCP:
npx -y grab@latest add mcpDisconnect an agent:
npx -y grab@latest remove [agent]Once installed, hover over any UI element in your browser and press:
- ⌘C (Cmd+C) on Mac
- Ctrl+C on Windows/Linux
This copies the element's context (file name, React component, and HTML source code) to your clipboard ready to paste into your coding agent. For example:
<a class="ml-auto inline-block text-sm" href="#">
Forgot your password?
</a>
in LoginForm at components/login-form.tsx:46:19If you're using a React framework or build tool, view instructions below:

import Script from "next/script";
export default function RootLayout({ children }) {
return (
<html>
<head>
{process.env.NODE_ENV === "development" && (
<Script
src="//unpkg.com/react-grab/dist/index.global.js"
crossOrigin="anonymous"
strategy="beforeInteractive"
/>
)}
</head>
<body>{children}</body>
</html>
);
}Add this into your pages/_document.tsx:
import { Html, Head, Main, NextScript } from "next/document";
export default function Document() {
return (
<Html lang="en">
<Head>
{process.env.NODE_ENV === "development" && (
<Script
src="//unpkg.com/react-grab/dist/index.global.js"
crossOrigin="anonymous"
strategy="beforeInteractive"
/>
)}
</Head>
<body>
<Main />
<NextScript />
</body>
</Html>
);
}Add this to your index.html:
<!doctype html>
<html lang="en">
<head>
<script type="module">
if (import.meta.env.DEV) {
import("react-grab");
}
</script>
</head>
<body>
<div id="root"></div>
<script type="module" src="/src/main.tsx"></script>
</body>
</html>First, install React Grab:
npm install react-grabThen add this at the top of your main entry file (e.g., src/index.tsx or src/main.tsx):
if (process.env.NODE_ENV === "development") {
import("react-grab");
}React Grab exposes the __REACT_GRAB__ API for extending functionality with plugins, hooks, actions, themes, and custom agents.
See packages/react-grab/src/types.ts and packages/react-grab/src/core/plugin-registry.ts for reference.
Or copy this into an agent to generate a plugin:
Clone https://github.com/aidenybai/react-grab into /tmp
Check these files for reference:
- packages/react-grab/src/types.ts (Plugin and PluginHooks interfaces)
- packages/react-grab/src/core/plugin-registry.ts (implementation)
Plugins are registered via `__REACT_GRAB__.registerPlugin({ name, hooks, actions, theme })`.
Add the code in client-side code (e.g., "use client" in Next.js) inside a useEffect after React Grab loads.
Generate an example plugin that logs when an element is selected.Want to try it out? Check out our demo.
