A calorie MCP that looks up calories and macros from a 4M+ food catalog, not model guesses.
Scored across 8 tools
Most tools have distinct purposes, but search_foods and suggest_foods both involve finding foods by name, which could cause confusion if the agent doesn't carefully read descriptions. Other tools like calculate_portion and get_food_nutrition are clearly differentiated by their output granularity.
All tool names follow a consistent snake_case verb_noun pattern (analyze_food_photo, calculate_macro_targets, get_food_nutrition, etc.), making the set predictable and easy to navigate.
Eight tools is well-scoped for a calorie/nutrition estimation server. Each tool serves a distinct input method or calculation need, and there is no redundancy or bloat.
The tool set covers all major input paths (name, photo, barcode, partial name) and core calculations (portion, recipe, macros, nutrition panel). No obvious lifecycle or calculation gaps exist for the stated purpose of estimating calories and macros.
Estimate calories and macros from a photo of food. Accepts a base64-encoded JPEG, PNG or WebP. Returns each detected food with its estimated weight and nutrition. Use when the user supplies a photo rather than naming a food. The photo must be passed as image_base64; clients do not attach images automatically.
Inputs: image_base64 (required), content_type.
Estimate daily calorie and macro targets from age, sex, weight, height, activity, and goal. Does not look up foods.
Inputs: age (required), goal (required), gender (required), activity (required), +2 more. Returns: result
Scale one food to a gram weight and return calories and macros. Use after search_foods when the user gives an amount.
Inputs: grams (required), food_id (required). Returns: result
Total and per-serving calories and macros for a list of ingredients. Each ingredient needs a food_id from search_foods and a gram weight.
Inputs: ingredients (required), servings. Returns: result
Return the nutrient panel for one food, per 100 g. Use the food_id from search_foods or lookup_barcode.
Inputs: food_id (required). Returns: result
Look up a UPC or EAN barcode and return macros per 100 g. Use when the user provides a barcode number.
Inputs: upc (required). Returns: result
Search a catalogue of over 4 million foods by name and return calories and macros per 100 g. Use this first whenever the user names a food. Returns a food_id for each result, which calculate_portion and get_food_nutrition accept.
Inputs: query (required), limit, verified_only. Returns: result
Typeahead suggestions for a partial food name. Use when the name is incomplete. Returns food_id and name only.
Inputs: query (required), limit. Returns: result
