Recipe Nutrition Calculator MCP

An MCP server that calculates nutrition facts for recipes using USDA FoodData Central data. It provides tools to look up ingredient nutrition, calculate total and per-serving values with FDA label rounding, round nutrition labels according to 21 CFR 101.9, and scale ingredient lines while recomputing nutrition.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

lookup_ingredient_nutrition — Look up USDA nutrients for an ingredient
Advertised by the server during the last successful anonymous check.
Advertised read-only

Returns USDA FoodData Central nutrient values per 100 g (calories, protein, total fat, saturated fat, carbohydrate, fiber, total sugars, sodium) for a common recipe ingredient, with its FDC id, the USDA household measures (1 cup, 1 tbsp, 1 large, 1 clove) in grams, and optionally the nutrients for an amount such as 1.5 cup or 3 large. 406 ingredients from SR Legacy and Foundation Foods, embedded, no API key. Use it instead of estimating nutrition from memory.

Advertised by the server during the last successful anonymous check.
Advertised read-only

Parses ingredient lines ("2 cups flour", "1 stick butter" as 8 tbsp, "3 large eggs", "1 lb ground beef"), converts cups, spoons and counted items to grams with USDA household measure weights for that specific food, and sums USDA FoodData Central nutrients. Returns per-line grams and matches, recipe totals, per-serving values, and the per-serving values rounded by the FDA Nutrition Facts rules (21 CFR 101.9) with percent Daily Value. Lines it cannot match are listed, never guessed.

round_nutrition_label — Round values for an FDA Nutrition Facts label
Advertised by the server during the last successful anonymous check.
Advertised read-only

Applies the FDA Nutrition Facts rounding rules from 21 CFR 101.9(c) to unrounded per-serving values: calories (under 5 = 0, nearest 5 up to 50, nearest 10 above), fat and saturated fat (nearest 0.5 g under 5 g), sodium (nearest 5 mg up to 140 mg, nearest 10 above), carbohydrate, fiber, sugars, added sugars and protein (nearest gram, "less than 1g" rules). Adds percent Daily Value from the 2,000-calorie DRVs (fat 78 g, saturated fat 20 g, sodium 2,300 mg, carbohydrate 275 g, fiber 28 g, added sugars 50 g). Rules copied from the eCFR text.

Advertised by the server during the last successful anonymous check.
Advertised read-only

Scales ingredient lines by a factor or from original to target servings (parses mixed numbers and fraction characters), then recomputes total and per-serving nutrition with USDA FoodData Central values and FDA label rounding for the scaled recipe.
