In Module 2 you handed the agent tools you wrote by hand. Real agents reach dozens of services — and writing every tool by hand doesn't scale. The Model Context Protocol (MCP) flips it around: you point the agent at a server and it *discovers* the tools. By the end of this module you'll connect your agent to a live Help Desk two ways — hand-wired HTTP and MCP — run the same agent against both, and see in the trace exactly what MCP does for you.
