Digest

Local-first nutrition tracking that runs inside Claude. You log food by chatting. Your data lives in a SQLite file on your machine — no account, no cloud, no signup. A color-coded dashboard shows five numbers at a glance: calories, protein, fiber, carbs, fat. Protein and fiber are targets. Carbs and fat are limits. That's the whole product.

Note: This is a pre-alpha release (0.0.1) reserving the package name while development continues. The core functionality works, but features are still being added. Watch the repo for the 0.1.0 release.

What Digest does

• Search foods across USDA FoodData Central (380K+) and Open Food Facts (4M+ branded products)
• Barcode lookup (UPC/EAN)
• Log meals via natural conversation — calories, protein, carbs, fat, fiber
• Track goals as targets (protein, fiber) or limits (carbs, fat)
• Visual dashboard — color-coded progress bars with a calorie ring, updates in place
• Edit and delete entries with natural language
• CSV export so your data is never locked in

What Digest doesn't do, by design

• No meal plans or recipe suggestions
• No grocery lists
• No social feed, streaks, or gamification
• No coaching, nudges, or "helpful" reminders
• No account, login, or cloud sync
• No ads, ever

Label photos work. Snap a picture of any nutrition facts panel, paste it into chat, and Claude reads the numbers and logs them. No special tool needed.

Data location

All data lives in ~/.digest/digest.db — a single SQLite file. Delete it and it's gone. Export to CSV anytime. Query it directly with sqlite3 if you want.

Install

pip install digest-mcp

Configure (Claude Desktop)

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "digest": {
      "command": "digest-mcp",
      "env": {
        "USDA_API_KEY": "DEMO_KEY"
      }
    }
  }
}

The DEMO_KEY works for light personal use (~30 requests/hour). For higher limits, get a free key at fdc.nal.usda.gov/api-key-signup.

Restart Claude Desktop, and Digest's tools become available in any chat.
