Look Up Food Nutrition
Search for any food and get detailed nutritional information including calories, protein, fat, and carbohydrates.
Build Nutrition Labels
Generate nutrition facts data for recipes and food products by aggregating ingredient-level nutritional information.
Quick answer: Use the Nutrition Data tool through ToolRouter to build nutrition labels directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolEvery packaged food product needs a nutrition label, and every recipe blog benefits from one. But creating accurate nutrition labels requires looking up every ingredient, adjusting for quantities, accounting for cooking losses, and formatting the result according to regulatory standards. It is one of the most tedious parts of food product development.
The search_foods and get_nutrition skills provide the raw data needed to build nutrition labels from scratch. Look up each ingredient in a recipe, get the per-serving nutritional breakdown, aggregate the totals, and you have the foundation for a standard nutrition facts panel. This works for food manufacturers developing new products, recipe bloggers adding nutrition info to their posts, meal prep services labeling their offerings, and restaurants adding calorie counts to menus.
While the final label still needs formatting and regulatory compliance review, having accurate nutritional data for every ingredient is the hardest and most time-consuming part. This tool handles that lookup and calculation in seconds.

Claude builds nutrition labels through an iterative recipe conversation. List your ingredients and quantities, let Claude look up each one, then refine serving sizes and adjust for cooking losses through follow-up questions. The result is a complete nutrition facts panel you can tweak by swapping ingredients and immediately seeing how the label changes.
How to build nutrition labels
Once connected (see setup above), use the Nutrition Data tool — the same steps work with Claude, ChatGPT, Microsoft Copilot, OpenClaw, and any MCP client:
- Ask Claude: "Look up nutrition for each ingredient in this recipe and create a nutrition label: 400g chicken, 200g rice, 100g peppers, 30ml olive oil"
- Claude looks up each ingredient and aggregates the totals
- Ask: "Format this as a standard nutrition facts panel for 4 servings"
- Use the generated label for your product or recipe
Example prompt
Try this with the Nutrition Data tool
I need a nutrition label for my granola recipe: 200g oats, 50g honey, 30g coconut oil, 50g almonds, 30g dried cranberries. This makes 10 servings. Calculate per-serving nutrition facts.
Tips
- Always specify the number of servings to get accurate per-serving values
- Ask Claude to format the output matching FDA nutrition label standards
- Include all ingredients, even small amounts of oil or seasoning -- they add up
