AI-generated overview

Read-only US food formulation and regulatory helper: FDA GRAS notice search, retailer ingredient rules, sugar swaps, RACC categories and Nutrition Facts label…

What you can do
  • Search FDA GRAS notices by substance, intended use or notifier, with GRN numbers, dates and FDA response letters
  • Screen ingredients against private-label rules of seven US retailers (Trader Joe's, Whole Foods, Kroger Simple Truth, Walmart, Sam's Club, Aldi, Sprouts)
  • Calculate sweetener equivalents for sugar, calories saved and bulk lost, with sweetness, kcal/g and glycemic index
  • List FDA RACC categories and reference amounts for serving sizes
  • Look up nutrients per 100 g, label declaration names and allergens in a USDA-based ingredient library
  • Calculate FDA Nutrition Facts labels from a formula, including rounding, % Daily Values, serving sizes, allergen statements and nutrient-content…
When to use it
Useful when drafting or checking US food and beverage formulations: verifying GRAS status, testing whether ingredients fit a retailer's private-label standards, planning sugar reduction, or building and validating Nutrition Facts labels.
Requirements
Remote streamable HTTP endpoint; no authentication, environment variables or headers are declared. Network access to the hosted endpoint is required.
Before you install
Results are decision support, not regulatory approval, so label and compliance decisions still need expert review. Tools are described as read-only, but formulas and ingredient data are sent to a third-party hosted service.

Installation

In SourceWeft

  1. Open SKS Nutrition AI in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.kewang93%2Fsks-nutrition-ai/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

search_gras_notices

Search FDA GRAS notices

Search the FDA GRAS (Generally Recognized as Safe) Notice inventory by substance, intended use or notifier. Returns GRN number, substance, intended use, basis, notifier, filing/closure dates and FDA's response letter (e.g. 'FDA has no questions'). Useful for checking whether a food ingredient has a GRAS notice before formulating for the US market. A missing notice does not mean an ingredient is not GRAS (self-affirmed GRAS exists), and a notice covers only its stated uses.

Parametersfieldlimitqueryrequired

check_retailer_ingredients

Check ingredients against US retailer private-label rules

Screen food ingredients against the public private-label ingredient rules of 7 US retailers: Trader Joe's (TJ), Whole Foods Market (WFM), Kroger Simple Truth (ST), Walmart (WMT), Sam's Club (SAM), Aldi (ALDI) and Sprouts (SPR). Covers about 54 ingredients and classes (synthetic colors, high-intensity sweeteners, preservatives, emulsifiers, fats, flavors). Statuses: BANNED, BANNED_BY_PRINCIPLE, ALLOWED_NAMED, CONDITIONAL, NOT_LISTED (not the same as approved), UNVERIFIED, CONFIRM_WITH_BUYER. Public lists are not full specifications: always confirm with the buyer.

Parametersretailersingredientsrequired

sweetener_sugar_replacement

Sugar replacement calculator

Calculate how much of a sweetener matches the sweetness of a given amount of sugar (sucrose), the calories saved, and the bulk (grams of solids) lost that must be replaced with fiber, polyol or another bulking agent. Also returns the sweetener's relative sweetness, kcal/g, glycemic index, heat/acid stability and regulatory notes from the SKS Sweetener Atlas.

Parameterssweetenerrequiredsugar_gramsrequired

list_racc_categories

List FDA RACC categories

List FDA Reference Amounts Customarily Consumed (RACC, 21 CFR 101.12) product categories used for Nutrition Facts serving sizes. Returns each category's id, group, name, reference amount and household measure hint. Optional filter words, e.g. 'cookie', 'carbonated beverage' or 'sauce'.

Parameterslimitquery

search_label_ingredients

Search the nutrition ingredient library

Search the SKS nutrition ingredient library (largely USDA-based) for an ingredient's nutrients per 100 g, label declaration name and allergens. Each result says where its data comes from and which nutrients are missing.

Parameterslimitqueryrequired

calculate_nutrition_label

Calculate an FDA Nutrition Facts label

Calculate a US FDA Nutrition Facts label from a formula: FDA rounding (21 CFR 101.9), % Daily Values, RACC-based serving size, servings per container, single vs dual-column format, plus ingredient, allergen and net-quantity statements and nutrient-content claim checks. Ingredient quantities are batch amounts; nutrients are per 100 g of each ingredient. Missing nutrients are treated as 0 and reported back, so the label is only as good as its inputs: it must be verified before printing.
