An [MCP](https://modelcontextprotocol.io) server that gives Claude a **USDA-accurate food
database and deterministic macro math** — so it looks nutrition numbers up instead of
recalling them, and calculates portions in Python instead of doing mental arithmetic.

Ask *"build me a high-protein vegan dinner at 40g protein, 30g carb, 15g fat"* and you get
an answer whose numbers are exactly right, because a linear solver produced them.

```
You: high protein vegan dinner, 40g protein / 30g carb / 15g fat

Claude: 147 g Beans (Dry) ....... 37.5g pro,    0g carb,  1.5g fat
        5 oz Sweet Potato ......  2.5g pro,   30g carb,    0g fat
        0.96 tbsp Olive Oil ....    0g pro,    0g carb, 13.5g fat
        -----------------------------------------------------------
        Total .................. 40.0g pro, 30.0g carb, 15.0g fat — 415 kcal
```

## Why this exists

LLMs are unreliable at two things this domain depends on: recalling specific nutrition
values, and arithmetic. Ask a model for the macros in 6 oz of chicken breast and you get a
plausible number that is often wrong by 15–20%.

This server removes both failure modes. It contains **no AI logic at all** — no model
calls, no embeddings, no semantic search. It is a database and a pile of arithmetic. The
calling model does the reasoning ("what counts as light?", "what goes with salmon?") and
this server supplies every number.

## Install

Requires [uv](https://docs.astral.sh/uv/) (or any Python 3.10+ environment). Nothing else —
no API key, no network access, no external services. It runs f…
