react-grab — Browser Element Context for AI Agents

Keyword: react-grab · grab · element context · copy component to ai

Point at any UI element in your browser, press Cmd/Ctrl+C, and instantly copy its React component name, source file path, and HTML markup to clipboard — ready for your AI coding agent.

When to use this skill

  • Set up react-grab in a React project (Next.js, Vite, Webpack) for AI-assisted development
  • Point at UI elements and copy precise component context to Claude Code / Cursor / Copilot / Gemini
  • Add react-grab MCP server so your AI agent can receive element context programmatically
  • Configure react-grab with a custom plugin for project-specific workflows (Jira, Figma, etc.)
  • Use the programmatic API (getElementContext, freeze) for automation or test tooling
  • Remove react-grab from a project or a specific agent integration

Instructions

  1. Run bash scripts/install.sh (or npx -y grab@latest init) to install react-grab in your project
  2. Start your dev server — react-grab is dev-only and never ships to production
  3. Open your app in a browser, hover over any element, and press Cmd+C (Mac) / Ctrl+C (Win)
  4. Paste the clipboard content into your AI coding agent (Claude Code / Cursor / Copilot / Gemini)
  5. Optionally run bash scripts/add-agent.sh mcp to enable MCP tool access for programmatic use

For detailed API and framework-specific setup, see references/api.md.

Examples

Copy element context to Claude Code

# 1. Start your app
npm run dev

# 2. Hover over a button in the browser
# 3. Press Cmd+C (Mac) or Ctrl+C (Win/Linux)
# Clipboard now contains:
#
# in LoginForm at components/login-form.tsx:46:19
#
# <button class="btn-primary" type="submit">
#   Log in
# </button>

# 4. Paste into Claude Code — it knows exactly where the component lives

Set up MCP integration

# Install react-grab MCP server
npx -y grab@latest add mcp

# Your AI agent can now call the get_element_context MCP tool
# to receive element context after you select it in the browser

Add custom plugin action

import { registerPlugin } from "react-grab";

registerPlugin({
  name: "open-in-figma",
  actions: [{
    id: "figma",
    label: "Find in Figma",
    shortcut: "F",
    onAction: (ctx) => {
      window.open(`figma://search?q=${ctx.componentName}`);
    },
  }],
});

Quick Start

# One command — auto-detects your framework and installs everything
npx -y grab@latest init

# Add MCP server for programmatic AI agent access
npx -y grab@latest add mcp

# Add to a specific AI agent
npx -y grab@latest add claude-code

After installation, hover over any element in your browser during development and press:

  • Mac: Cmd+C
  • Windows/Linux: Ctrl+C

Output copied to clipboard:

in LoginForm at components/login-form.tsx:46:19

<a class="ml-auto text-sm underline-offset-4 hover:underline">
  Forgot your password?
</a>

Paste directly into your AI coding agent prompt — no file searching needed.

Installation

Auto-detect (Recommended)

npx -y grab@latest init

Detects your framework (Next.js App Router / Pages Router / Vite / TanStack Start / Webpack) and package manager (npm / yarn / pnpm / bun) automatically.

Manual installation by framework

Next.js App Router (app/layout.tsx):

import Script from 'next/script'

export default function RootLayout({ children }) {
  return (
    <html>
      <body>
        {children}
        {process.env.NODE_ENV === "development" && (
          <Script
            src="//unpkg.com/react-grab/dist/index.global.js"
            crossOrigin="anonymous"
            strategy="beforeInteractive"
          />
        )}
      </body>
    </html>
  )
}

Next.js Pages Router (pages/_document.tsx):

import Script from 'next/script'

// Inside _document component:
{process.env.NODE_ENV === "development" && (
  <Script
    src="//unpkg.com/react-grab/dist/index.global.js"
    crossOrigin="anonymous"
    strategy="beforeInteractive"
  />
)}

Vite (index.html):

<script type="module">
  if (import.meta.env.DEV) {
    await import('//unpkg.com/react-grab/dist/index.global.js');
  }
</script>

Webpack (entry file):

if (process.env.NODE_ENV === 'development') {
  import('react-grab');
}

Package install (for programmatic use):

npm install react-grab
# or: pnpm add react-grab | yarn add react-grab | bun add react-grab

Install react-grab via skill scripts

# Auto-detect framework and install
bash scripts/install.sh

# Install for a specific framework
bash scripts/install.sh --framework next-app

# Add to a specific AI agent
bash scripts/add-agent.sh claude-code
bash scripts/add-agent.sh cursor
bash scripts/add-agent.sh mcp

Core Usage

Keyboard shortcut

In development mode:

  1. Hover over any React element in the browser
  2. Press Cmd+C (Mac) or Ctrl+C (Windows/Linux)
  3. The context is copied to clipboard

Output format:

in <ComponentName> at <file-path>:<line>:<col>

<element-html>

Floating toolbar

A draggable toolbar appears in the corner of your browser when react-grab is active:

  • Click to toggle activation on/off
  • Drag to any screen edge
  • Collapse when not needed

Multi-element selection (drag)

Click and drag across multiple elements to capture all their contexts at once. Each element's component stack and HTML is included in the clipboard output.

Programmatic API

import { getGlobalApi } from "react-grab";

const api = getGlobalApi();

// Activate the overlay
api.activate();   // show overlay
api.deactivate(); // hide overlay
api.toggle();     // toggle

// Copy an element's context to clipboard
await api.copyElement(document.querySelector('.my-button'));

// Get source info without copying
const source = await api.getSource(element);
console.log(source.filePath);     // "src/components/Button.tsx"
console.log(source.lineNumber);   // 42
console

How to use react-grab on Cursor

AI-first code editor with Composer

1

Prerequisites

Before installing skills in Cursor, ensure your development environment meets these requirements:

  • ›Cursor installed and configured on your development machine
  • ›Node.js version 16.0+ with npm package manager (verify with node --version)
  • ›Active project directory or workspace where you want to add react-grab
2

Execute installation command

Execute the skills CLI command in your project's root directory to begin installation:

$npx skills add https://github.com/supercent-io/skills-template --skill react-grab

The skills CLI fetches react-grab from GitHub repository supercent-io/skills-template and configures it for Cursor.

3

Select Cursor when prompted

The CLI will show a list of available agents. Use arrow keys to navigate and space to select Cursor:

◆ Which agents do you want to install to?
│
│ ── Universal (.agents/skills) ── always included ────
│ • Amp
│ • Antigravity
│ • Cline
│ • Codex
│ ●Cursor(selected)
│ • Cursor
│ • Windsurf
4

Verify installation

Confirm successful installation by checking the skill directory location:

.cursor/skills/react-grab

Reload or restart Cursor to activate react-grab. Access the skill through slash commands (e.g., /react-grab) or your agent's skill management interface.

⚠

Security & Verification Notice

We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.

Skills execute code in your development environment. Always verify the publisher's identity, review recent commits, and test in isolated environments before production deployment.
