How to Build MCP Servers

Wes and Scott dive into the Model Context Protocol (MCP)—a lightweight, standardized way to expose external tools (like currency converters or file access) to AI systems. They discuss:

  • Core components: what MCP is and why it's valuable for AI tool integration.
  • Building an MCP server: covering authentication, transport strategies (e.g. standard I/O and Server-Sent Events), and real-time communication.
  • Tooling ecosystems: including the MCP Inspector, reusable prompt patterns, and the difference between MCP servers and traditional “tool calling.”
  • Use cases: from local vs. remote servers to applying MCP in IDEs and chats, with mentions of libraries like mcp-server-cloudflare and use-mcp.

They wrap the chat by exploring practical MCP providers and tossing in their “sick picks”—Wes recommends Mario Kart World, and Scott suggests the anyloop kids’ smartwatch.
