MCP Dev Summit North America

The AI hype cycle promised full automation. Reality delivered hallucinations and agents that guess when they should ask. The MCP spec offers a different vision—humans in control through rich, interactive collaboration rather than micromanaging every step.

This talk explores how recent MCP primitives transform the protocol from text-in-text-out tool-calling into interactive human-agent workflows. We'll cover elicitations that let servers ask clarifying questions with structured forms, async tasks that pause for human decisions and resume seamlessly, and MCP Apps that render interactive UIs—charts, dashboards, confirmations—in sandboxed iframes. Each makes feedback loops faster and agent interactions richer.

Using VS Code's implementation as reference, we'll demonstrate patterns for adaptive autonomy, progressive input gathering, and bidirectional workflows where servers drive the conversation. You'll leave with concrete patterns for building MCP integrations that treat collaboration as a feature, not a fallback.
