MCP Mastery: Build, Secure, and Ship Model Context Protocol Servers Track
Module 1 of 8
What MCP Is and Why It Became Agent Connective Tissue
The protocol from first principles: the M-by-N integration problem it solves, the three primitives (tools, resources, prompts), the host/client/server model, the stdio vs HTTP transports, and why building your own server is the highest-leverage agent skill.

What You'll Learn
- Explain the M-by-N integration problem and why a shared protocol like MCP collapses it into M-plus-N work
- Describe the host, client, and server roles and how a single agent talks to many servers at once
- Distinguish the three server primitives (tools, resources, prompts) and when each is the right shape for a capability
- Choose between the stdio and streamable HTTP transports based on where the server runs and who needs to reach it
