2surfaces — web & iPhone
Your agent does the typing.
01
Connect your agent
Point ChatGPT, Claude, or any MCP client at the endpoint and approve access once over OAuth 2.1.
02
Log by conversation
Your agent searches the curated catalog, logs meals and supplements, and pulls goal progress — mid-chat.
03
See it everywhere
The day updates instantly on the web dashboard and the iPhone app: rings, macros, and activity-adjusted targets.
Inside Sitos
A log built for the people who actually read the label.
Eight things Sitos does differently — data quality, agent access, and AI capture, at a glance.
Own your data
Your log, your data — exportable, portable, yours.
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.
Connect AI agents
Connect any LLM through MCP — log meals by chat.
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.
Every nutrient
Track every nutrient — macros and 30+ micros.
Vitamins, minerals, omegas. 39 fixed nutrient columns per food, computed at query time so retroactive corrections propagate everywhere.
AI label scanning
Snap a label, get a logged food.
Point your camera at a nutrition panel. The model parses the columns, normalizes per-100g, and proposes a verifiable food entry in seconds.
AI recipe generation
Paste an ingredient list — get a logged recipe.
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.
Activity-aware
Targets that move with you.
Intervals.icu syncs your runs, rides, and lifts; Withings syncs weight and body fat. Daily kcal and macro targets adjust automatically — no manual reconciliation.
Honest log
Per-instance overrides for real life.
Half a portion, out of avocado, swapped the rice — override the instance, leave the canonical recipe untouched. Macros recompute live.
For developerssearch · log · recipes · goals · history
One endpoint. OAuth 2.1. Fourteen tools.
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/mcpWhy invite-only?
Sitos keeps its food database hand-curated — every entry is checked before it can be logged. Slow growth is the feature that keeps the data trustworthy.
Who owns the data?
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.
Which agents work?
Anything that speaks MCP: ChatGPT connectors, Claude (web, desktop, and Code), Cursor, or your own client. API keys cover headless scripts and cron.
