Evolving AI chat with MCP Apps
Interacting with AI is still mostly text: you type, it calls tools and generates responses. But text is the wrong UI for many tasks and leads to awkward experiences. We've been building great experiences on the web for years, so let's bring that into chat.
The MCP Apps extension is a proposed standard, inspired by MCP-UI and OpenAI's Apps SDK, that adds a UI layer to MCP that agents can render, generating real, web-powered interfaces that users can control from inside the chat.
In this talk you'll learn how to build interactive UIs that run inside AI chats. We'll start with a standard MCP server, add a UI component to display results, then make it interactive. We'll see the experience evolve from plain text to a mini-app inside the chat that can call tools and carry on the conversation. You'll leave ready to bring your app to life inside AI chats.
