api record

USDA FoodData Central (FDC) — authoritative US food composition database (~400K+ foods). Key workflow: usda_search_foods → fdcId → usda_get_food (single), usda_get_foods (batch), or usda_compare_foods (comparison). Use usda_list_nutrients to resolve nutrient names to numeric IDs before filtering.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • usda_list_nutrients unknown never probed

    Look up the FDC nutrient reference table — all tracked nutrients with their numeric IDs, names, SR reference numbers, units, and categories. Use to resolve a nutrient name (e.g. "vitamin C") to its FDC ID (1162) before passing it to the nutrients[] filter on other tools. Filter by category (macronutrients, vitamins, minerals, lipids, amino_acids, or other) to narrow results. The data is static — call once and reuse the IDs.

  • usda_search_foods unknown never probed

    Search USDA FoodData Central foods by keyword. Returns matching foods with FDC IDs and a preview of key nutrients (energy, protein, fat, carbs — not guaranteed complete). Use the returned fdcId with usda_get_food for the full nutrient profile, or usda_compare_foods for side-by-side comparisons. When dataType is omitted, defaults to SR Legacy (common whole foods with complete profiles) — or to Branded when brandOwner is set, since only Branded records carry one. Set dataType to ["Branded"] for packaged products, or include a UPC/GTIN code as the query. Pass brandOwner (e.g. "General Mills") to narrow branded results.

  • usda_get_food unknown never probed

    Get the full nutrient profile for one food by FDC ID. Returns all available nutrients (or a filtered subset via the nutrients[] param) with optional per-portion scaling. Use usda_search_foods to discover FDC IDs. Provide quantity + unit to scale all nutrient values from per-100g to the specified portion (e.g. quantity=200, unit="g" → per-200g values). Use unit="serving" to scale to the food's first defined portion weight. Narrow nutrients[] to specific IDs to reduce response size for focused queries.

  • usda_get_foods unknown never probed

    Fetch nutrient profiles for 2–20 foods in a single API call. More efficient than calling usda_get_food N times when you already have multiple FDC IDs. All values are per 100g (no portion scaling). Use the nutrients[] filter to limit response size — strongly recommended for batch calls. For side-by-side comparison with a formatted table, use usda_compare_foods instead. Failed IDs (not found or no data) are reported in the failed[] array rather than aborting the entire batch.

  • usda_compare_foods unknown never probed

    Compare nutrients side-by-side for 2–5 foods. Returns a structured table — one row per nutrient, one column per food — formatted as markdown. Best for "spinach vs kale iron" or "which has more protein?" questions. Omit nutrients[] to use the 12 most common defaults (energy, protein, fat, saturated fat, carbs, fiber, sugars, sodium, potassium, calcium, iron, vitamin C); provide nutrients[] with specific FDC IDs to compare different nutrients. All values are scaled to the same gram basis (default 100g). If one or more FDC IDs are not found, the comparison proceeds with the valid foods — only throws too_few_foods when fewer than 2 IDs return data.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ how we know
card completeness
90%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
