Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Snacky log 150g chicken breast and 200g cooked rice for lunch"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
A protein and calorie log that you never have to open to fill in. You tell a chat assistant what you ate (a message, a voice note, a recipe portion, a photo of a label or a plate), and the assistant calls Snacky's MCP tools. Snacky looks the food up in a nutrient database and keeps the log. A small web UI shows the day and the week and lets you correct entries.
Status: early. The MCP server runs; the web UI is not built yet.
The assistant names foods and grams. The numbers come from a database: the German Bundeslebensmittelschlüssel, Open Food Facts, or the recipe's own nutrition in Tandoor. A number the model estimated is stored and shown as an estimate.
Each log entry keeps a copy of its nutrients, so correcting a food later does not change past days.
One process owns one SQLite file. It serves MCP on one port and the web UI on another.
docs/ARCHITECTURE.md has the data model and the interfaces.

pinned BLS download at build time. Without that file the server starts and
skips BLS, with a warning. /data is the only path written at runtime.
