MCP Server Builder

About

The MCP Server Builder skill provides a comprehensive framework for architecting and implementing Model Context Protocol (MCP) servers in Python or TypeScript. It emphasizes agent-centric design principles, focusing on creating workflow-driven tools rather than simple API wrappers. The skill guides developers through every phase of the development lifecycle—from initial API research and schema definition using Pydantic or Zod, to safe testing practices and the creation of robust evaluation harnesses that ensure high-reliability performance for AI agents.
