This walks you through building MCP servers that let LLMs interact with external APIs. It covers the full cycle: researching the MCP spec and target API, implementing tools with proper schemas and error handling, testing with the MCP Inspector, and creating evaluation questions to verify your server actually works. The guide pushes you toward TypeScript with streamable HTTP for remote servers, emphasizes comprehensive API coverage over workflow shortcuts, and includes concrete advice on tool naming and response formatting. The evaluation phase is thorough, requiring 10 complex read-only questions with verifiable answers. If you're shipping an MCP server and want a structured process instead of guessing at best practices, this gives you a clear roadmap.
