MCP’s newer capabilities let us build richer interactions between assistants, applications, and people: server events, long-running tasks, requests for user input, and interactive MCP Apps.

In this demo-driven talk, we’ll explore what those capabilities make possible, from reacting to changing data to following background work and using an app inside a conversation. Drawing on lessons from Lovable, we’ll share what worked, what broke, and what makes these integrations reliable. You’ll leave with ideas for your own applications and a clear view of what’s supported today and what’s still emerging.
