Overview

Lecka MCP is an open-source project that provides a race nutrition planning tool for endurance athletes. The tool calculates carb, sodium, and fluid targets, as well as provides Lecka product recommendations based on race type, conditions, and athlete weight. The project is built using Node ESM and utilizes the @modelcontextprotocol/sdk dependency. The tool consists of several components, including a server, tools, and engine, which work together to provide a comprehensive nutrition planning solution. The server acts as the entry point, with three registered tools: get-products, calculate-fueling, and get-nutrition. The engine is responsible for calculating nutrition targets and providing product recommendations. The project also includes a configuration file, formula-config.json, and a products.json file, which provides bundled fallback data. The tool is designed to be used by endurance athletes and coaches to optimize nutrition planning and improve performance.
