Building with AI Agent Protocols

The agentic AI landscape is rapidly evolving from isolated experiments to production-ready products, but a critical challenge remains: how do we build solutions that enable AI agents to reliably interact with tools, services, and each other? We've heard about MCP, ACP, A2A… but which protocols bring leverage to building solutions today? This talk explores the emerging standards that product teams are using to build real user-facing solutions. Model Context Protocol (MCP): The open standard for connecting AI systems to external data and tools—with practical lessons from shipping MCP-powered features. MCP Apps: How integrating user interfaces directly into the agent experience is turning agents from backend utilities into products users actually interact with. Agent Communication Protocol (ACP): Standardizing how a frontend can interface with a stateful, asynchronous agent backend. Drawing from real-world product development, we'll cover architectural patterns that work in production, performance considerations that affect user experience, and the path from prototype to shipped product.
