MCP Dev Summit North America

When the backend can reason, what does that mean for the frontend? Let's look at how to build UIs that support reasoning and adapt to any task.

The way we interact with software is changing. LLM-powered applications, with human-in-the-loop, are handling repetitive tasks that used to require forms and workflows. But bolting a chatbot onto your existing UI isn't enough - extracting structured data from natural language is fragile, adding frustration and friction for users.

In this talk, we'll explore how tool-calling and protocols like MCP provide deterministic contracts with non-deterministic systems, what human-in-the-loop looks like when the UI adapts to the task at hand rather than forcing users through fixed workflows.
