mcp-veggie

MCP server for tracking weekly Aarstiderne veggie box deliveries. Translates Danish produce names, provides USDA-sourced freshness windows, generates zero-waste recipes via local LLM, and alerts when items are about to expire.

Built for a family of 3 in Denmark (two adults, one texture-sensitive 7-year-old). Deployed on a K3s cluster alongside an Ollama instance.

Produce Knowledge Base

A 151-item knowledge base (src/seed/produce-knowledge.json) provides Denmark-specific produce intelligence loaded into memory at startup. Each entry includes:

• Danish season data — peak months, source (Danish farm vs import)

• Yield notes — practical quantities for meal planning ("500g carrots = 400ml soup base for 2")

• Preservation methods — 2-4 practical methods per item with effort level and shelf life

• Waste rescue — specific "it's going soft, do THIS now" advice per item

• Flavor pairings — what goes well together and what to avoid

• Kid strategy — acceptance level, texture notes, winning preparations, and hiding methods for a texture-sensitive child

• Ethylene data — producer/sensitive classification drives storage co-location warnings

• Box priority — days_to_use_first_in_box (1-3) used as eating-order tiebreaker

This data enriches LLM prompts for recipes and meal plans, powers waste-rescue suggestions in alerts, and provides ethylene storage warnings in freshness reports.

Setup

cp .env.example .env
# Edit .env with your Ollama host and box URL
npm install
npm run build
npm start

Requires:

• Node.js 22+

• Ollama running with qwen3.6:27b (or any model via LLM_MODEL env var)

• An Aarstiderne box subscription URL

Configuration

Architecture

• Transport: Streamable HTTP (MCP SDK 1.29.0) -- stateless per-request

• Database: SQLite with WAL mode, Drizzle ORM

• LLM: Ollama native API with think: false for fast structured output

• Provider: Aarstiderne BOM API (no auth required)

• Translation: Seed cache of 93 Danish produce names + LLM fallback

• Freshness: 151-item USDA dataset + LLM fallback with conservative bias

• Produce Knowledge: 151-item in-memory knowledge base with Danish-specific context, kid strategies, ethylene data, and preservation methods

K8s Deployment

kubectl apply -f k8s/

The deployment expects:

• A PVC named mcp-veggie-data for the SQLite file

• Ollama accessible at the LLM_BASE_URL in the configmap

• ghcr-creds imagePullSecret for the container image
