Summary
This is a comprehensive reference for building MCP servers, covering everything from basic architecture to tool design patterns and security practices. Use it when you're implementing MCP tools or resources and need quick answers on schemas, error handling, or transport types. It's dense with tables and checklists, so it works best as a lookup guide rather than a tutorial. The practical bits on tool naming, input validation, and the current spec features (tool annotations, outputSchema) are immediately actionable. If you're wiring up Claude to external systems via MCP, keep this one loaded.
