cronometer-mcp

An MCP (Model Context Protocol) server that provides access to your Cronometer nutrition data. Pull detailed food logs, daily macro/micro summaries, manage diary entries, fasting, biometrics, and recurring foods — all from Claude, Cursor, or any MCP-compatible client.

Requires a Cronometer Gold account (or any paid tier that supports web login).

Features

• Food log — individual food entries with full macro and micronutrient breakdown
• Daily nutrition — daily calorie, protein, carb, fat, and fiber totals
• Micronutrients — detailed vitamin/mineral breakdown with period averages
• Diary management — add/remove food entries, copy entire days, mark days complete
• Recurring foods — create, list, and delete repeat items that auto-log on selected days
• Macro targets — read/write daily targets, create templates, set weekly schedules
• Fasting — view history and stats, cancel or delete fasts
• Biometrics — log and remove weight, blood glucose, heart rate, body fat
• Raw CSV export — servings, daily summary, exercises, biometrics, or notes
• Sync to disk — download JSON exports and generate a markdown food log

1. Install

pip install cronometer-mcp
