Build an MCP Nutrition Server

Build an MCP Nutrition Server

Short summary

A tutorial for building an MCP (Model Context Protocol) server that wraps the DietlyAPI for nutrition data lookup. The server exposes two narrow tools — search_foods and get_food — so AI clients like Claude and Cursor fetch real nutrition data instead of hallucinating values. Includes full Python implementation with FastMCP, configuration for Claude Desktop, and guidance on keeping tool surfaces small and nullable values honest.
