We all know how to build MCP servers by now. If not, no worries, we cover that too. But did you know your tools need proper authentication? Most MCP servers out there have no auth layer at all and that is a security gap sitting in production. In this session you learn how MCP Auth locks down your tool connections and how Remote MCP moves your servers to the cloud so they are not stuck running on someone's laptop.

Then we go further. What happens when your agent needs help from another agent on a completely different team? That is A2A. Agents discover each other through Agent Cards, negotiate what they can do, and delegate tasks across system boundaries without anyone writing custom glue code.

Then there is Gemini Skills. Instead of building every capability from scratch, you give your agent pre-built reusable skills that let it handle specific tasks out of the box, think of them like plugins your agent can use to instantly get better at things without you writing the logic yourself. You leave knowing how all three protocols connect, when to use which one, and with working code that wires them together.
