Schema Quality & AI Usability68
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 863 tokens (~215/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management7
  • Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

MCP tools · 4 exposed · ~863 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
calculate_recipe_nutrition ~180

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.

NameTypeReqDescription
linesarrayyesIngredient lines, one per item, amount first: "2 cups all-purpose flour", "1/2 cup butter", "2 large eggs", "200 g chicken breast", "1 tsp salt".
servingsnumber–Number of servings the recipe makes. Default 1.

No output schema declared.

No examples provided.

lookup_ingredient_nutrition ~223

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.

NameTypeReqDescription
amountnumber–Optional amount to compute nutrients for, e.g. 1.5.
ingredientstringyesIngredient name, e.g. "cheddar cheese", "brown rice", "olive oil", "large egg".
unitstring–Unit for amount: g, oz, lb, kg, cup, tbsp, tsp, fl oz, ml, or "each" for a counted item (uses the USDA medium or large size). Default g.

No output schema declared.

round_nutrition_label ~301

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.

NameTypeReqDescription

scale_recipe_nutrition ~159

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.

NameTypeReqDescription
factornumber–Multiply every quantity by this, e.g. 2 or 0.5. Or give servings instead.
linesarrayyesIngredient lines, one per item, amount first: "2 cups all-purpose flour", "1/2 cup butter", "2 large eggs", "200 g chicken breast", "1 tsp salt".

Install

How do I install the Recipe Nutrition Calculator MCP server?

Recipe Nutrition Calculator is a hosted endpoint at https://recipe-nutrition-calculator-mcp.lipmichal.workers.dev/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Common questions

What is the Recipe Nutrition Calculator MCP server?

Recipe Nutrition Calculator is an MCP server listed in the public MCP registry as io.github.theluckystrike/recipe-nutrition-calculator-mcp. Recipe nutrition from ingredient lines: USDA FoodData Central values, per serving, FDA rounding. This page covers its hosted endpoint (https://recipe-nutrition-calculator-mcp.lipmichal.workers.dev/mcp).

Is the Recipe Nutrition Calculator MCP server safe to use?

Recipe Nutrition Calculator scores 66 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the Recipe Nutrition Calculator MCP server expose?

Recipe Nutrition Calculator exposes 4 tools: lookup_ingredient_nutrition, calculate_recipe_nutrition, round_nutrition_label, scale_recipe_nutrition. Their descriptions and schemas cost roughly 863 tokens of context every time the server is loaded.

Does the Recipe Nutrition Calculator MCP server require authentication?

No. We connected to Recipe Nutrition Calculator without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the Recipe Nutrition Calculator MCP server still maintained?

Recipe Nutrition Calculator is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
