Heathy — nutrition data (MCP server)

Nutrition for 917 whole plant foods and 39 Ayurvedic herbs, reconciled across 11 national food-composition datasets — including IFCT 2017 (India), which isn't available as an API anywhere else.

Endpoint: https://mcp.heathy.org/mcp — Streamable HTTP (JSON-RPC 2.0) Website: https://heathy.org · Contact: hello@heathy.org Free while in preview.

This repository contains documentation only — the manifest and these notes. The server is hosted; there is nothing to install.

What makes it different

Most nutrition APIs hand back a single number from a single national table. This one returns the number and its provenance:

• the median across every dataset that has the food,
• how many sources contributed and which ones,
• the min–max spread between them.

So an agent can cite a figure instead of asserting it, and can tell when the sources disagree. Guava vitamin C, for example, comes back as 228 mg from 10 sources with a range of 99.2–273 — a spread worth knowing about before stating it as fact.

Indian foods are the standout. IFCT 2017 isn't queryable as an API elsewhere, so questions about karela, horse gram or millets get real data rather than a US substitute.

No API key, no signup. A service card describing the server is at https://mcp.heathy.org/.

Tools

lookup_food

Full per-100 g nutrient profile for a whole plant food, with provenance.

search_foods

Resolve a name to a slug, including Hindi, Sanskrit and botanical aliases. Call this first when you have a plain-English or local name.

nutrient_ranking

Rank foods by a nutrient per 100 g — the "highest in iron" question.

herb_monograph

An Ayurvedic herb monograph. Traditional use and modern research are kept strictly separate — traditional records what the tradition claims, modern records what research shows with an evidence tier. Every response carries a mandatory safety block (cautions, pregnancy guidance, drug interactions).

Examples

Response shape

Every tool returns the same envelope:

{
  "data":        { /* the payload */ },
  "attribution": ["USDA FoodData Central …", "IFCT 2017, ICMR–NIN …"],
  "source_url":  "https://heathy.org/food/guava-flesh-only-raw/",
  "disclaimer":  "Informational only — not medical advice.",
  "license":     "https://heathy.org/terms/"
}

Please reproduce attribution and disclaimer when you use a response, and cite source_url. For herbs, surface the safety block alongside any information you pass on.
