Loewen Menu

MCP (Model Context Protocol) server for the Löwen Menü IBS5 school-lunch ordering system. Lets an LLM browse weekly menus, manage a shopping cart, and place meal orders via the IBS5 web portal at ibs.loewen-menue.de.

Features

• Browse weekly meal plans by calendar week
• View order history
• Add/remove meals from the shopping cart
• Confirm orders
• Multi-profile support (order for multiple children from one server)

Requirements

• Python 3.10+
• uv package manager
• A Löwen Menü IBS5 account

Setup

# Clone and install
git clone https://github.com/yourusername/loewen-menu-mcp.git
cd loewen-menu-mcp
uv sync

Configuration

Credentials are passed via the PROFILES environment variable:

PROFILES=child1:CUSTOMER_ID:PASSWORD

For multiple children:

PROFILES=child1:S000001:1234,child2:S000002:5678

If only one profile is configured, it is used as the default and the profile parameter can be omitted from all tool calls.

Usage with Claude Desktop

Add to your Claude Desktop MCP config (~/.claude/settings.json or a project-level MCP file):

{
  "mcpServers": {
    "loewen-menu": {
      "command": "/bin/bash",
      "args": ["-c", "cd /path/to/loewen-menu-mcp && uv run server.py"],
      "env": {
        "PROFILES": "child1:S000001:1234,child2:S000002:5678"
      }
    }
  }
}

MCP Tools

Tool	Description
list_profiles	List configured profiles (children)
get_weekly_menu	Browse meals for a given calendar week
get_order_history	View past orders (filterable by days back and search text)
get_cart_status	Check shopping cart contents and balance
add_to_cart	Add a meal to the cart (does not finalize the order)
confirm_order	Finalize and submit all items in the cart
remove_meal	Remove a meal from the cart

Ordering flow

1. get_weekly_menu — see what's available
2. add_to_cart — add meals (repeat for each day/meal)
3. get_cart_status — verify the cart
4. confirm_order — submit the order

How it works

The server authenticates to IBS5 using a Base64-encoded Bearer token built from the customer ID and password. Credentials are configured server-side via environment variables and never pass through the LLM.

Weekly menus and order history are scraped from server-rendered HTML pages. Cart operations and order confirmation use JSON API endpoints.
