Turns recipe ingredient lines into per-serving nutrition using USDA FoodData Central values. Converts cups, spoons and counted items to grams, scales recipes to a new serving count, and rounds results to FDA Nutrition Facts label rules with percent Daily Value. Ingredients it cannot match are listed, not guessed. No account or API key needed.

Example request: "Work out the calories and nutrition facts per serving for my lasagna recipe, which makes 8 servings."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Recipe Nutrition Calculator to help me. It is a free service with an MCP server at https://recipe-nutrition-calculator-mcp.lipmichal.workers.dev/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- lookup_ingredient_nutrition: 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
- calculate_recipe_nutrition: 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 
- round_nutrition_label: 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, 
- scale_recipe_nutrition: 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.
