A skill that guides building MCP servers in Python (FastMCP) or Node and TypeScript, from research through evaluations.

The SKILL.md lays out four phases: research and planning, implementation, review and testing, and creating evaluations. It points to reference files for the MCP protocol, SDK documentation and language-specific guides.

It is part of the example-skills bundle in the anthropics/skills marketplace, installed as a whole rather than skill by skill.
