MatMCP 🛒

An MCP (Model Context Protocol) server that provides AI assistants with tools to interact with Mathem.se, a Swedish online grocery store. Search for ingredients, add items to your basket, and manage recipes directly through your AI assistant.

Features

• Search Ingredients: Find products on Mathem.se by name or description

• Add to Basket: Add products directly to your Mathem.se shopping cart

• Recipe Management: List and fetch detailed recipe information

• Structured Data: Get clean, structured product and recipe data

Prerequisites

• macOS/Linux: This guide assumes macOS, but Linux instructions are similar

• Python 3.12+: Required for the project

• uv: Fast Python package manager

• Mathem.se Account: For adding items to basket functionality

Installation

1. Install uv (Python package manager)

2. Clone and setup the project

3. Install dependencies

4. Configure Mathem.se authentication (optional)

For basket functionality, you need to provide your Mathem.se session cookies:

1. Copy the example cookie file:

   cp cookie.txt.example cookie.txt

2. Get your session cookies from Mathem.se:

   • Open your browser and go to mathem.se

   • Log in to your account

   • Open Developer Tools (F12)

   • Go to the Network tab

   • Refresh the page

   • Find a request to mathem.se and copy the Cookie header value

   • Paste it into cookie.txt

   The format should look like:

   sessionid=your_session_id_here; csrftoken=your_csrf_token_here; other_cookies=value

Note: Without cookies, you can still search for ingredients, but adding to basket will not work.
