Description

Log food to Google Health by talking to Claude — automatic nutrition lookup via USDA/Open Food Facts, an MCP server on Render, Neon Postgres for entry tracking, and a custom OAuth 2.1 shim for Claude's connector requirement.

Installation

This entry records only its repository, not the path inside it, so there is no exact command to give. Open the source below and copy the folder into ~/.claude/skills/, or the file into ~/.claude/agents/.

README

Claude Fit Logger

Log food and drink to Google Health by just talking to Claude — from your phone, no manual entry. Claude looks up nutrition automatically (USDA / Open Food Facts, falling back to its own estimate when nothing matches), writes it to Google Health, and keeps a running daily table in chat with support for undo and corrections.

How it works

You (phone) → Claude (chat + skill) → MCP server (Render)
                                          ├─ Nutrition lookup (USDA / Open Food Facts)
                                          ├─ Entry log (Neon Postgres) — powers undo/remove
                                          └─ Google Health API — the actual food log

Full breakdown, including a diagram, in [`docs/architecture.pdf`](docs/architecture.pdf).

Status

Working end-to-end: logging, automatic nutrition lookup with manual fallback, undo, remove, and running totals all sync correctly to the Google Health app. Single-user by design — see [`docs/security.pdf`](docs/security.pdf) for why that matters before extending this to anyone else.
