A first-class MCP server, a curated food database, and an API your agents can actually use. Sitos plugs straight into the assistants and workflows you already run.

Point ChatGPT, Claude, or any MCP client at the endpoint and approve access once over OAuth 2.1.
Your agent searches the curated catalog, logs meals and supplements, and pulls goal progress — mid-chat.
The day updates instantly on the web dashboard and the iPhone app: rings, macros, and activity-adjusted targets.
Eight things Sitos does differently — data quality, agent access, and AI capture, at a glance.
290+ foods hand-checked for provenance, kind, per-100g macros and 30+ micronutrients — plus 6,800+ high-confidence entries from Germany's licensed BLS food-composition database. Search-first, no user-contributed noise.
Postgres under the hood, row-level security on every table. Export the full history any time. No lock-in, no resale, no ads training on your meals.
First-class Model Context Protocol server. Hook up Claude, ChatGPT, or your own agent and let it search foods, log meals, and pull macros over OAuth.
Vitamins, minerals, omegas. 39 fixed nutrient columns per food, computed at query time so retroactive corrections propagate everywhere.
Point your camera at a nutrition panel. The model parses the columns, normalizes per-100g, and proposes a verifiable food entry in seconds.
Drop a copied recipe, a chat reply, or a photo of a card. Sitos extracts ingredients, picks verified matches, and saves a per-instance-overridable recipe.
Intervals.icu syncs your runs, rides, and lifts; Withings syncs weight and body fat. Daily kcal and macro targets adjust automatically — no manual reconciliation.
Half a portion, out of avocado, swapped the rice — override the instance, leave the canonical recipe untouched. Macros recompute live.
A native SwiftUI app with the same curated database, activity-adjusted goals, and one-tap logging — in sync with the web and your agents.
Add the connector in ChatGPT or Claude, or wire up your own MCP client. Agents search foods, log meals and supplements, manage recipes, and read goal progress — scoped to their user, revocable any time. Headless scripts use API keys instead.
https://mcp.sitos.app/mcpSitos keeps its own catalog hand-curated — every entry checked before it can be logged — and layers on Germany's licensed BLS food-composition database for thousands more high-confidence foods. Slow growth on the curated core is the feature that keeps the data trustworthy.
You do. Postgres under the hood with row-level security, full export (JSON or CSV) any time, no resale, no ads, no training on your meals.
Anything that speaks MCP: ChatGPT connectors, Claude (web, desktop, and Code), Cursor, or your own client. API keys cover headless scripts and cron.
