Summary
This is a comprehensive guide for building MCP servers that actually work well with LLMs. It walks you through the full process from studying the protocol docs to implementing tools with proper schemas and error handling. The skill covers both TypeScript and Python approaches, emphasizes workflow-focused tool design over basic API wrappers, and includes specific guidance on naming conventions and response formats. What makes this useful is the evaluation framework at the end that helps you test whether LLMs can actually accomplish real tasks with your server, plus the concrete code quality checklists for each language.
