MyFitnessPal — Claude Code MCP server: setup
Connects an AI coding client to your MyFitnessPal diary for food logging, product lookup, and nutrition analysis.
claude mcp add --env MFP_COOKIE=<MFP_COOKIE> --env MFP_USERNAME=<MFP_USERNAME> --transport stdio myfitnesspal -- uvx mfp-mcpWhat MyFitnessPal does
This MCP server lets Claude Code work with a MyFitnessPal diary through chat. It can add, edit, and remove diary entries, find foods with macro data, inspect daily meals, follow weight trends, and export nutrition history.
The process runs with uvx mfp-mcp and authenticates through a browser session cookie. You need uv and MFP_COOKIE before connecting it; the client configuration also uses MFP_USERNAME. Optional session renewal relies on a headless browser profile and Playwright. MyFitnessPal has no public API, so the server depends on private web endpoints and can stop working when the site changes.
What it helps with
- log meals into a MyFitnessPal diary
- find foods together with macro values
- review what was eaten on a given day
- track weight and nutrition trends
- export diary history for analysis
Example prompts for the agent
- Log a banana as a snack in MyFitnessPal.
- Show what I ate yesterday and group the entries by meal.
- Chart my weight for this month.
