## Overview

Stream Deck MK.2 has fifteen customizable LCD keys and runs through Elgato's desktop software. Its official SDK lets you build a plugin that reacts to presses and updates the keys. A coding agent can help scaffold the plugin and connect it to a local tool or service; the logic runs on the attached computer, not as a standalone application inside the deck.

Best for: Physical shortcuts and live status buttons for software you already use.

Not for: A standalone button that works without an attached computer.

Where code runs: Your plugin runs through Stream Deck software on the connected computer, not inside the deck as an independent app.

## Project ideas

- One button to start a focus session

- A live status key for your side project

- A physical control panel for your own software

## What you need

- Stream Deck MK.2 and a compatible computer

- Current Stream Deck desktop software

- Node.js and the tools in the official plugin guide

## Compatibility and cautions

- The deck depends on the attached computer and Stream Deck software; it is not an autonomous network button.

- Check current plugin-development requirements separately from older hardware minimum specifications.

- Keep confirmations around destructive shortcuts, messages, payments, or actions that affect other people.

## Planning notes (not a replacement for the original technical instructions)

1. **Set up a normal key first**: Install the desktop software and confirm the device works with a built-in action.

2. **Scaffold the example plugin**: Follow Elgato's getting-started guide and keep its sample action working before adding a service.

3. **Give one button a useful job**: Add a harmless local action, then a status indicator. Keep keys and tokens out of the distributed plugin bundle.

## Coding-agent project brief

Help me create a Stream Deck MK.2 plugin with the current official SDK. First check the required desktop software and Node.js versions. Start with one harmless button and a visible success/error state. Explain where the plugin runs and require confirmation before any destructive or externally visible action.

## Common questions

### Can Claude Code or Cursor build a Stream Deck plugin?

They can help scaffold and explain a plugin using Elgato’s current SDK. You still need the supported desktop software, Node.js tooling, and local testing on your computer.

### Does Stream Deck MK.2 work without a computer?

Not for the plugin route described here. The deck depends on the attached computer and Stream Deck software. For hub-based logic, compare Flic Button + Hub LR.
