digest-mcp

Local-first nutrition tracking MCP server for Claude Desktop. Log meals by chatting with Claude, see macros in a visual dashboard. No cloud, no account, no subscription.

> Pre-alpha. Expect rough edges and breaking changes. Feedback welcome.

• Log meals by chatting. "I had two eggs and a slice of toast" — Claude looks up the foods, picks portions, writes them to your local database.
• Visual dashboard. Calories, protein, carbs, fat, fiber against your goals. Renders as an in-chat artifact that updates in place — no window flipping.
• Barcode lookup. Read the barcode off a package, get the entry.
• Label photos. Snap a nutrition label, Claude reads it natively.
• Goals you set once. Calories and macro targets stored locally.
• Your data stays yours. Everything lives in ~/.digest/digest.db on your machine. SQLite. Export to CSV anytime.

No meal plans. No grocery lists. No social feed. No streaks or gamification. No coaching nudges. No account. No cloud. No ads. No subscription.

It's a log and a dashboard. That's the whole product.

• USDA FoodData Central — 380K+ generic and branded foods, public domain
• Open Food Facts — 4M+ products, CC0, great for barcodes and international brands

Both are queried together and results deduplicated.
