This has been very inspiring for a MCP design novice like me; I can now implement executable tools, reference knowledge, and user workflows in my own MCP.

This was my first "real" MCP server (previously I made an MCP server to control a Furby for GitHub Universe) and I learned a lot. A few things I learned (not an expert):

* Tool vs. Resource: Does it compute or does it serve * Prompts -> Tools * Deterministic vs. Probabilistic is a choice per tool
