🔥 New take from JSNation Amsterdam, June 2026 👉 every interactive UI you've seen inside Claude, ChatGPT or Cursor runs on one open spec. And the apps sending that UI no longer see what you do with it.

⚡ Inside the talk:
🔹 How a server returns a live, interactive UI component instead of a wall of text
🔹 Why your app no longer owns the user journey - the agent assembles the interface from atoms
🔹 The distribution math nobody has priced in: 800M weekly users, 170x the App Store at launch, one codebase everywhere

🎙 Liad Yosef and Ido Salomon wrote this spec. They co-author and maintain MCP Apps on the MCP Steering Committee, built MCP-UI and GitMCP. Liad previously led agentic interfaces in Shopify's CEO office; Ido led end-user AI at Palo Alto Networks.
