MyFitnessPal MCP for Claude and ChatGPT vs a built-in fitness MCP server
ChatGPT Health listed MyFitnessPal among its connected apps at launch in January 2026; check the apps list in ChatGPT, because availability depends on country and changed with the July 2026 rollout. That is an in-ChatGPT connection, not an MCP server you can add to other assistants. We found no official MyFitnessPal MCP server or Claude connector as of November 15, 2026. For Claude there are only community projects. One popular server is built on the myfitnesspal Python library, which reads the website with your browser cookies, because MyFitnessPal has no public API for it. That works for reading a diary, but it is unofficial and can break when the site changes. revns ships its own MCP server as part of the product: OAuth 2.1 with PKCE, separate read and write permissions, and tools that log meals, set goals and plan the week, not only read them. If you want your existing MyFitnessPal history in ChatGPT, ChatGPT Health is the official route; for Claude, a community server is the only one today. If you want an assistant that can also log and plan, a built-in server is sturdier.
| MyFitnessPal MCP servers | revns | |
|---|---|---|
| Official MCP server or connector | Listed as a ChatGPT Health app at launch (January 2026; check your country). No official MCP server or Claude connector found as of Nov 15, 2026 | Yes, a remote server for Claude, ChatGPT, Claude Code and Cursor |
| How the assistant gets your data | In ChatGPT Health, a connection OpenAI offers. For Claude, community servers that use the myfitnesspal library and your browser cookies | OAuth 2.1 with PKCE; you choose read or write when you connect |
| Reads your food diary | Yes, through community servers | Yes: meals, protein, calories and macros if you log them |
| Writes data back | Varies by project; unofficial | Yes, with a separate write permission: quick_log, log_meal, set_goal, plan_day |
| Training, sleep and mood in the same tools | Food is the centre | Sessions, sleep, steps, meals and mood, scored together |
| If the vendor changes the site | Community servers can stop working | The server is first-party, so it changes with the app |
Where it is the better choice
MyFitnessPal has the largest food database and years of diary history for many people. If that history is what you want to ask ChatGPT about, check ChatGPT Health's apps list for your country; for Claude, a community MCP server is the way today. Check any such project's code and permissions before you give it a cookie or a login.
