🔥 Every interactive UI inside Claude, ChatGPT and Cursor runs on one spec: MCP Apps. ⚡ It's live in millions of Shopify stores, it powers Claude's Imagine - and it takes the user journey away from your app.
What's inside:
🔹 How a server returns a live UI component instead of text - SDK, sandbox, message flow
🔹 Why apps no longer own the user journey: the agent assembles the UI from atoms
🔹 The distribution math: 800M weekly users, 170x the App Store at launch, one codebase
