Cellarion MCP Server

Cellarion

Cellarion is a hosted wine cellar app — a ready-to-use online service at cellarion.app. Create a free account and start tracking your bottles, organizing them into cellars and racks, searching a shared wine registry, getting drink-window recommendations, and chatting with an AI sommelier about your collection. No installation, no server, no setup — just sign up and go. Every feature is free, forever.

Just want to use Cellarion? Go to cellarion.app and sign up. You do not need to clone this repository, run Docker, or host anything yourself.

Cellarion is also open-source (AGPL-3.0), so if you'd prefer to run your own private instance, you can self-host it. The rest of this README covers self-hosting — see Quick Start. Most people should just use the hosted service at cellarion.app.

Hosted Service (recommended)

Cellarion is live and publicly available at:

👉 https://cellarion.app

This is the primary way to use Cellarion. Create an account and start using the full service today — every feature is free, forever. No credit card, no trial clock, no paywalled features, nothing to install or maintain.

Features

• Bottle tracking — Log every bottle with vintage, producer, region, price, rating, and tasting notes
• Cellar & rack management — Organize bottles across multiple cellars with interactive 8×4 rack grids

Self-Hosting (Quick Start)

This section is only for people who want to run their own private instance. If you just want to use Cellarion, head to cellarion.app instead — no setup required.

Prerequisites

• Docker + Docker Compose

Run the app

The app is routed through Traefik, so create the external web Docker network before the first up (compose declares it external — the first command fails otherwise):

git clone https://github.com/jagduvi1/Cellarion.git
cd Cellarion
cp .env.example .env
# Edit .env and set JWT_SECRET and MEILI_MASTER_KEY to strong random strings
docker network create web        # once; skip if it already exists
docker-compose up --build

Seed demo data

After the containers are running:

docker exec cellarion-backend node src/seed-demo.js

This creates:

…plus 2 countries, 2 regions, 5 grape varieties, 2 wine definitions, and a demo cellar with sample bottles.

These are local development credentials. Change them before deploying anywhere public.

Stop

docker-compose down          # keep data
docker-compose down -v       # also remove all volumes (wipes database)

Services

All external traffic enters through Traefik (runs on the shared web Docker network, external to this Compose file). All services inside this Compose file are internal only.

Running behind Traefik

Cellarion is designed to sit behind a Traefik reverse proxy on a shared Docker network called web. Traefik handles incoming HTTP on port 80 (SSL termination is handled upstream by Cloudflare or similar).

Requirements:

• A running Traefik instance connected to an external Docker network named web
• The web network must exist before starting Cellarion: docker network create web

The frontend service declares the following Traefik labels in docker-compose.yml:

traefik.enable: "true"
traefik.docker.network: "web"
traefik.http.routers.cellarion.rule: "Host(`cellarion.app`)"
traefik.http.routers.cellarion.entrypoints: "web"
traefik.http.services.cellarion.loadbalancer.server.port: "8080"

The upstream port is 8080 (not 80): the frontend image is built on nginxinc/nginx-unprivileged, whose non-root nginx cannot bind ports below 1024.

Update the Host(...) rule to match your own domain.

API Summary

Auth — /api/auth

Cellars — /api/cellars (auth required)

Bottles — /api/bottles (auth required)

Wine Registry — /api/wines (auth required)

All wine registry endpoints require a valid JWT. Behaviour differs by role:

• Regular users — search param is mandatory; results capped at 10.
• Admin / Sommelier — full browse without a search term; no result cap.

Chat — /api/chat (auth required)

Notifications — /api/notifications (auth required)

Stats — /api/stats (auth required)

Support — /api/support (auth required)

Wine Reports — /api/wine-reports (auth required)

Wine Requests — /api/wine-requests (auth required)

Sommelier — /api/somm/* (somm or admin role)

Admin — /api/admin/* (admin role required)

Super Admin — /api/superadmin/* (super admin only)

---

Environment Variables

Copy .env.example to .env in the project root and set the required values:

AI Cellar Chat

The AI chat feature requires three services working together:

1. Anthropic Claude (ANTHROPIC_API_KEY) — generates conversational responses grounded in your cellar
2. Voyage AI (VOYAGE_API_KEY) — creates wine embeddings for semantic search
3. Qdrant (QDRANT_URL) — vector database for fast similarity search

When all three are configured, users can ask natural-language questions about their collection (food pairings, occasion picks, cellar insights). The system only surfaces wines the user actually owns — no hallucinated recommendations.

A single daily usage quota — the same for every user, regardless of supporter tier — is configurable by SuperAdmins (default 50 questions/day).

Self-hosted AI (OpenAI-compatible endpoints)

Self-hosters who prefer not to use an Anthropic API key can point every LLM feature (cellar chat, label scan, import lookup, drink-window / price / profile suggestions) at any endpoint that speaks the OpenAI chat-completions API — Ollama, LM Studio, vLLM, LiteLLM, or OpenAI itself:

AI_PROVIDER=openai
OPENAI_BASE_URL=http://host.docker.internal:11434/v1   # your endpoint's /v1 root
AI_MODEL=llama3.1:70b                                   # any model your server hosts
AI_VISION_MODEL=qwen2.5-vl:32b                          # optional — used for label scanning

Wine embeddings (the semantic-search half of cellar chat) can independently be moved off Voyage AI the same way:

EMBEDDING_PROVIDER=openai
EMBEDDING_MODEL=nomic-embed-text   # any embedding model your server hosts
EMBEDDING_DIMENSION=768            # MUST be that model's real vector size
# EMBEDDING_BASE_URL / EMBEDDING_API_KEY default to OPENAI_BASE_URL / OPENAI_API_KEY

Notes:

• Both switches are opt-in: without them, nothing changes — Anthropic + Voyage remain the defaults, and they can be switched independently (e.g. local LLM + Voyage embeddings).
• host.docker.internal resolves out of the box only on Docker Desktop (Windows/macOS). On a Linux server, either add extra_hosts: ["host.docker.internal:host-gateway"] to the backend service in your compose file, or point OPENAI_BASE_URL at the host's LAN IP or a service on the compose network.
• The AI usage budgets (per-user/global daily caps, import per-request cap, chat daily limit) were tuned to bound paid Anthropic spend. Against your own hardware they still apply — raise or disable them in SuperAdmin → Rate limits (0/-1 = unlimited) if you don't want your local endpoint metered.
• The admin panel's Claude model settings are ignored in openai mode (the model comes from AI_MODEL); the configurable AI prompts still apply.
• Label scanning needs a vision-capable model. Extraction quality depends heavily on the model you host — smaller local models will misread more labels than Claude does.
• The Qdrant collection is sized to the embedding dimension. After changing EMBEDDING_PROVIDER, EMBEDDING_MODEL, or EMBEDDING_DIMENSION, run a full embedding job (SuperAdmin → AI) — it drops and rebuilds the collection at the new size. Every returned vector is validated against EMBEDDING_DIMENSION, so a wrong value fails loudly instead of corrupting search.
• Qdrant itself is always required for cellar chat (it ships in docker-compose).
• Privacy note for multi-user instances: the bundled Privacy Policy names Anthropic and Voyage AI as the AI sub-processors. Pointing these vars at your own local endpoint (Ollama/vLLM on your hardware) removes third-party AI processing entirely — but if you point them at a remote third-party service (e.g. OpenAI or a hosted proxy), you are responsible for updating your instance's privacy policy and user consent accordingly.

Email Verification

When both MAILGUN_API_KEY and MAILGUN_DOMAIN are set, email verification is enabled:

• New users receive a verification link after registering and cannot log in until they click it.
• The link expires after 24 hours. A resend option is available on the login page and the /verify-email page.
• If Mailgun is not configured, registration issues a token immediately — the same behaviour as before.

Existing users: After enabling verification on a running instance, existing accounts will have emailVerified: false and will be locked out. Run this once in the MongoDB shell to restore access:

db.users.updateMany({ emailVerified: { $exists: false } }, { $set: { emailVerified: true } })

---

Bottle Import

Users can import bottles from other wine cellar apps (Vivino, CellarTracker, or any generic CSV). The import flow:

1. Upload — Drop a CSV file; the system auto-detects the source format and maps it to a standard schema
2. Validate — Each item is matched against the wine library using fuzzy search (Meilisearch + MongoDB text search + normalized key lookup) and scored with combined similarity
3. Review — Users see match results: exact matches (auto-selected), fuzzy matches (pick from candidates), and unmatched items (search manually or skip)
4. Import — Confirmed items are created as bottles in the target cellar

Import sessions are persisted so users can resume later if interrupted. Access the import from any cellar's overflow menu (⋯ → Import Bottles). Requires editor or owner access.

Master Import JSON Format

Bottles can also be imported as JSON. Each item supports:

{
  "wineName": "Albe",
  "producer": "G.D. Vajra",
  "vintage": "2019",
  "country": "Italy",
  "region": "Piedmont",
  "appellation": "Barolo",
  "type": "red",
  "price": 299,
  "currency": "SEK",
  "bottleSize": "750ml",
  "quantity": 2,
  "purchaseDate": "2024-03-15",
  "purchaseLocation": "Systembolaget",
  "notes": "Beautiful nebbiolo",
  "rating": 4.2,
  "ratingScale": "5",
  "rackName": "Rack A",
  "rackPosition": 5,
  "addToHistory": false
}

To import directly into history (already consumed bottles), add:

{
  "addToHistory": true,
  "consumedReason": "drank",
  "consumedAt": "2025-12-24",
  "consumedNote": "Opened for Christmas",
  "consumedRating": 4.5,
  "consumedRatingScale": "5",
  "dateAdded": "2024-06-01"
}

Cellar Export

Cellar owners can export their data via a cellar's overflow menu (⋯ → Export) or Settings. Available as JSON, or as a ZIP that also includes your uploaded bottle images. The export covers bottles with rack placement (rackName, rackPosition), rack geometry, the 3D room layout, and your own reviews. The JSON format is directly re-importable.

---

Wine Deduplication

When an admin creates a wine, the system checks for near-duplicates using:

1. Levenshtein distance (40%) — character-level similarity
2. Trigram Jaccard (30%) — overlapping 3-char sequences
3. Token Jaccard (30%) — word-level similarity after removing wine domain stop words

Score: name × 0.45 + producer × 0.45 + appellation × 0.10

Candidates above the threshold (default 0.75) appear as warnings with a "Use This" option.

---

Testing

Frontend

cd frontend && npm test -- --watchAll=false

Uses Jest + React Testing Library (bundled with Create React App). Covers drink-window logic, currency conversion, and the shared Modal component.

Backend

cd backend && npm test

Uses Jest. Covers auth middleware, cellar access control, wine normalisation/similarity, rating scale conversion, and drink-window classification.

Run both test suites before opening a pull request. PRs with failing tests will not be merged.
