graziechef-mcp (@deusflight/graziechef-mcp on npm)

Restaurant math for your AI assistant. This is an MCP server for chefs, restaurant owners and consultants: food cost, menu price with VAT, recipe scaling and the EU 14 allergens matrix, using the same formulas as the free tools on graziechef.com/tools.

The calculations run locally. There is no API key, no account and no network call.

Tools

Tool	What it answers
food_cost_calculator	Cost of a dish from its ingredients, the price that hits your target food cost %, and your actual food cost % at the current price.
menu_price_calculator	From plate cost and target food cost: net price, price including VAT, menu price rounded up to a clean step, gross profit and real food cost after rounding.
recipe_scaler	Scale a recipe from N to M portions. Returns every scaled quantity, plus batch cost and cost per portion when unit costs are given.
allergen_matrix	The dish x allergen table required in the EU (Reg. 1169/2011, Annex II), with the dishes to avoid for each allergen. Accepts English, Italian or common names ("shrimp", "dairy").

currency is an optional ISO code (default EUR) and only affects formatting.

Ask your assistant things like:

• "My carbonara uses 0.12 kg guanciale at €18/kg, 0.1 kg pasta at €2/kg and 2 eggs at €0.30. What should it cost on the menu at 28% food cost with 10% VAT?"
• "Scale this tiramisu from 6 to 40 portions."
• "Build the allergen matrix for my menu."

Example output (menu_price_calculator, plate cost 3.20, 30% target, 10% VAT, round to 0.50):

Net price (before tax): €10.67
Price incl. 10% tax: €11.74
Menu price (rounded up to 0.5): €12.00
Gross profit per plate (net of tax): €7.71
Real food cost after rounding: 29.3%

Each result ends with a link to the matching interactive tool on graziechef.com.

Notes

• The allergen tool does not guess allergens from dish names. You declare them, and it builds the table. Always check recipes and supplier labels.
• Run the tests with npm test. They start the server over stdio and call every tool.
