Add a food item to your MyFitnessPal food diary for a specific date and meal.

This tool adds a food entry to your diary. You can search for foods using mfp_search_food to find the food ID (mfp_id) needed for this tool.

Args: params: AddFoodToDiaryInput containing: - mfp_id (str): MyFitnessPal food item ID (from mfp_search_food) - meal (str): Meal name - 'Breakfast', 'Lunch', 'Dinner', or 'Snacks' (default: 'Breakfast') - date (str, optional): Date in YYYY-MM-DD format, defaults to today - quantity (float): Number of default servings for this food (default: 1.0)

Returns: str: Confirmation message with details of the added food entry

Create a new custom food in the MyFitnessPal database (via the v2 API).

Use this when a food is not already in MyFitnessPal (mfp_search_food returns nothing suitable) and you want it available to log. All nutrition values are entered PER ONE serving_size (e.g. serving_size='125 g' with the numbers for a 125 g portion).

On success the new food's id is returned as mfp_id; pass it to mfp_add_food_to_diary to log the food (it may take a short moment to also surface in mfp_search_food). Calling this repeatedly creates duplicate foods.

IMPORTANT: share_public=True submits the food to MyFitnessPal's shared public database and is IRREVERSIBLE -- public foods can no longer be edited or deleted. Leave it False (default) to create a private food you can later delete.

Args: params: CreateFoodInput containing: - description (str): Food name (required) - brand (str, optional): Brand/manufacturer - calories, fat, carbs, protein (float): Core macros per serving (required) - saturated_fat, polyunsaturated_fat, monounsaturated_fat, trans_fat, fiber, sugar, sodium, potassium, cholesterol, vitamin_a, vitamin_c, calcium, iron (float, optional): Additional nutrients per serving - serving_size (str): Serving-size label, e.g. '1 Serving', '125 g' (default '1 Serving') - servings_per_container (float): Servings per container (default 1.0) - share_public (bool): Submit to the public database; irreversible (default False)

Returns: str: JSON confirmation including the new food's mfp_id

Update an existing MyFitnessPal diary entry.

Supports changing the meal, quantity, serving size, and date for an entry previously returned by mfp_get_diary (use response_format='json' to get the entry_id). MyFitnessPal can rewrite an entry during edit and return a replacement row, so the response includes current_entry_id and entry_id_changed to keep callers tracking the right diary row.

Args: params: UpdateFoodEntryInput containing: - entry_id (str): Diary entry ID from mfp_get_diary JSON output - date (str, optional): Date in YYYY-MM-DD format, defaults to today - meal (str, optional): New meal name - quantity (float, optional): New number of servings - unit (str, optional): New serving-size label - weight_id (str, optional): Raw MFP serving-size option ID

Returns: str: Confirmation with the current entry id and whether it changed

Delete an existing MyFitnessPal diary entry.
