Local-first nutrition MCP for AI agents — food search, barcode lookup, photo-assisted meal estimation, intake logging, hydration, goals and coach-style workflows. No OAuth, no hosted account.

Front door

• Install one connector — npx -y wellness-nourish setup --client claude
• Run it in Claude · Cursor · ChatGPT · Hermes · OpenClaw — see the client examples.
• Local-first — your tokens and food logs never leave your machine (privacy).
• Which connector should I use? — see the front-door guide.

Quickstart (60 seconds)

npx -y wellness-nourish doctor
npx -y wellness-nourish search banana
npx -y wellness-nourish barcode 0000000000000
npx -y wellness-nourish log --preview "2 ovos, banana e café preto"

doctor checks readiness, search/barcode hit the food providers, and log --preview estimates a meal locally without writing anything.

Zero-secret demo (offline, no API key)

NOURISH_FIXTURE_MODE=1 serves the bundled fixtures/ instead of calling USDA or Open Food Facts, so you can see the exact shape of every response with zero network access or keys:

$ NOURISH_FIXTURE_MODE=1 wellness-nourish search banana
Bananas, raw	usda	89 kcal/100g
BANANA	usda	312 kcal/100g

Try it with your agent

Three copy-paste prompts, all backed by existing tools:

• "Estimate the calories and protein in 2 eggs, a banana and black coffee." → nourish_estimate_meal
• "Look up the barcode 737628064502 and tell me what it is." → nourish_lookup_barcode
• "What should I eat next today, given my goals?" → nourish_daily_coach / nourish_suggest_next_meal

Mutating tools (log intake, water, goals, clear-day) never run without explicit user save intent — they return USER_ACTION_REQUIRED until the agent passes explicit_user_intent: true.

Tools

Nourish exposes food search, barcode lookup (text + image), photo-assisted meal estimation, intake logging, hydration, goals, exports, daily/weekly summaries, personal meal memory, and coach-style workflows over stdio (default) or Streamable HTTP (POST /mcp).

• Full CLI (20+ commands), install, client configs & ChatGPT dashboard → docs/cli.md
• Hermes / Telegram personal setup (10-step flow) → docs/telegram.md
• Data providers & attribution (USDA, Open Food Facts, ZXing) → docs/providers.md
• pt-BR meal-estimator eval set (52 examples) → docs/evals/pt-br-meal-estimator.json
• Reproducible Telegram/Hermes demo transcript → docs/telegram-demo-transcript.json

Food photo decision tree

Agents should route Telegram/Hermes/OpenClaw food photos by the strongest signal they can extract:

1. Barcode is visible and image bytes are available: call nourish_lookup_barcode_image.
2. Barcode is blurry or no product is found: ask for sharper barcode digits, or call nourish_analyze_food_image with barcode_observation plus any OCR/meal clues.
3. Nutrition facts are readable: OCR the label and call nourish_analyze_food_image with product_name and nutrition_label_text.
4. It is a plate or unpackaged food: describe visible foods/portions and call nourish_analyze_food_image with detected_items or image_description.
5. Never log from an image response until the user confirms the product or meal, serving size and save intent.

Image tools accept exactly one of these input forms:

{ "image_path": "/tmp/telegram-food-photo.jpg" }

{ "image_base64": "<base64 image bytes>", "image_mime_type": "image/jpeg" }

{ "image_data_uri": "data:image/jpeg;base64,<base64 image bytes>" }

If barcode decoding fails, the response includes fallback and next_actions so the agent can ask the user for the typed digits, OCR the nutrition label, or route the photo as a meal without silently inventing a food.

The capture above is generated from a real MCP run in fixture mode with a temporary local directory:

npm run demo:capture

The committed transcript proves the exact tool sequence: nourish_estimate_meal → user confirmation → nourish_log_intake → nourish_daily_summary.

Privacy & what runs offline

Intake, hydration and goals are stored locally under ~/.wellness-nourish/ (override with NOURISH_LOCAL_DIR). The connector does not require hosted accounts and does not send local intake logs to Delx Wellness. Provider lookups may contact USDA FoodData Central or Open Food Facts — unless NOURISH_FIXTURE_MODE=1 keeps everything offline against the bundled fixtures.

Agents should never ask users to paste API keys, tokens, raw health exports, or private food logs into chat — configure secrets through environment variables or local files. Full detail in docs/providers.md.

Anchor question: "Should I train hard today?" — the demo combines wearable recovery signals with nutrition context to answer it. This is the shared, reproducible proof for the whole Delx Wellness stack.
