USDA FoodData Central is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
In Claude, open Settings, then Connectors.
Choose Add custom connector, give it a name, and paste the link.
If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.
Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude

Screened, no issues found
Screening looks for known threats and hidden instructions at the time of the check, and runs again weekly and whenever the tool list changes. It cannot see the server's code, so only connect what you need and review what Muse asks to do. How screening works.
usda_list_nutrientsLook up the FDC nutrient reference table — all tracked nutrients with their numeric IDs, names, SR reference numbers, units, and categories. Use to resolve a nutrient name (e.g. "vitamin C") to its FDC ID (1162) before passing it to the nutrients[] filter on other tools. Filter busda_search_foodsSearch USDA FoodData Central foods by keyword. Returns matching foods with FDC IDs and available preview nutrients: protein (1003), fat (1004), carbohydrate (1005), fiber (1079), and energy (1008, 1062, 2047, 2048), preserving distinct energy estimates. Missing nutrients are omitusda_get_foodGet the full nutrient profile for one food by FDC ID. Returns all available nutrients (or a filtered subset via the nutrients[] param) with optional per-portion scaling. Use usda_search_foods to discover FDC IDs. Values are per 100 g (basisUnit "g"), except Branded foods FDC repousda_get_foodsFetch nutrient profiles for several foods in one API call. More efficient than calling usda_get_food N times when you already have multiple FDC IDs. Accepts up to 500 IDs: repeats are dropped, the first 20 distinct IDs are fetched, and the rest are returned in deferredIds for a fusda_compare_foodsCompare nutrients side-by-side for 2–5 foods. Returns a structured table — one row per nutrient, one column per food — formatted as markdown. Best for "spinach vs kale iron" or "which has more protein?" questions.

At the last check (November 13, 2026, 11:45 UTC) the endpoint was working, answering in 97ms. Over the last 7 days it answered 100% of health checks. It is checked every 15 minutes.
It was screened on September 25, 2026 with the result "screened, no issues found". Screening checks the domain against threat feeds and reads the tools for hidden instructions and requests for passwords or card numbers. It cannot see the server's code, so grant only the access you need.
It exposes 5 tools, including usda_list_nutrients, usda_search_foods, usda_get_food, usda_get_foods. For example, you could ask Muse: "Compare the iron content in spinach versus kale to see which is better for my diet."
