lecka-mcp is an open-source project hosted on GitHub (https://github.com/mgnirck/lecka-mcp），为 The Lecka sports nutrition platform provides a Model Context Protocol (MCP) server.
In terms of purpose, the project targets the race nutrition planning scenario for endurance athletes. It exposes tool capabilities to compatible AI clients through the MCP protocol, enabling AI to query Lecka products, calculate race fueling plans, and retrieve personalized nutrition data. According to the project description, its planning can provide carbohydrate, sodium, and fluid intake targets based on race type, race conditions, and body weight, and recommend Lecka products accordingly.
In terms of main capabilities, the tool functions explicitly mentioned in the materials include: querying products, calculating race fueling plans, and retrieving personalized nutrition data. The project is built on @modelcontextprotocol/sdk and deployed on Vercel.
In terms of usage, the materials only state that it can be connected to Claude Desktop. Users need to add configuration in claude_desktop_config.json; on macOS, this configuration file is located at ~/Library/Application Support/Claude/claude_desktop_config.json. However, the materials do not provide the specific configuration content, installation commands, or running steps.
In terms of applicable scenarios, it is suitable for endurance athletes planning carbohydrate, sodium, and fluid intake before a race and obtaining Lecka product recommendations.
In terms of limitations, the materials do not explain the range of sports it supports, the Lecka data sources it relies on, whether a Lecka account or API key is required, whether it is paid, the detailed logic of the calculation model, or whether it supports MCP clients other than Claude Desktop. This information has not yet been provided.
