Per 100 g, from the TACO table

Kilo's food log for one day, in Portuguese: banana, boiled egg, French roll and rice, each with its calories

Work

Two projects.
Pick one.

Each one opens from the overview down to the proof. Move the depth, read the numbers.

An offline-first iPhone app for logging workouts and food, built for Brazilians.

Pre-launch

An MCP server that gives AI assistants the TACO, the Brazilian food composition table.

Open source

Weigh a plate
of Brazil.

Kilo carries the TACO, Brazil's food composition table, inside the app. taco-br-mcp hands the same table to AI assistants. Slide the grams: every number here is read straight from it.

Values per 100 g of edible portion from the TACO 4ª ed. (NEPA/UNICAMP, 2011), as published in taco-br-mcp's data. The page does the per-100 g arithmetic in your browser; the call above is the request shape from the README. Real plates vary. This is not medical or nutritional advice.

One table.
Six tools.

taco-br-mcp is open source. It gives an AI assistant exact numbers from the TACO instead of recalled ones, and says so when the table has no value.

Reachianhudson.ai@gmail.com

I'm a developer and solo founder. I design and build everything myself, from the app to the tooling around it.

My main project is Kilo, an offline-first iPhone app for logging workouts and food, made for Brazilians. I also publish open-source tools, like an MCP server that gives AI assistants access to Brazilian nutrition data.

More projects will land here as they ship.
