This walks you through building MCP servers that let LLMs talk to external APIs, whether you're using Python's FastMCP or the Node/TypeScript SDK. The real value is in the workflow design principles: it pushes you to build tools around complete tasks rather than just wrapping API endpoints, optimize for token limits with concise responses, and write error messages that guide the agent toward solutions. It includes comprehensive checklists for studying API docs, planning tool selection, and implementing pagination and formatting helpers. The guides cover both ecosystems with specifics on Pydantic vs Zod schemas, proper async patterns, and MCP-specific annotations like readOnlyHint and destructiveHint. Treats building for agents as a distinct discipline from standard API integration.
