Cronometer
A solid bridge to Cronometer's nutrition tracking if you have a paid account. It wraps the internal GWT-RPC protocol the web app uses to expose 20+ tools for reading food logs with full macro and micronutrient breakdowns, adding and removing diary entries, managing recurring foods, setting macro targets, tracking fasts, and logging biometrics like weight and blood glucose. The sync tool dumps JSON exports and generates a markdown food log to disk. Comes with hardcoded GWT magic values that may need updating when Cronometer deploys, but the README shows you how to sniff new ones from browser DevTools. Useful if you want Claude to analyze your nutrition data or automate logging without opening the app.
