My MCP Server

This project is a Model Context Protocol (MCP) server for interacting with the Mon Marché french grocery store website. It provides tools to search for products and add them to a cart using a command-line interface.

• Add Products to Cart: Add products to your cart by specifying their name.
• Session Management: Automatically logs in and manages session cookies for interacting with the website.

Prerequisites

• Node.js (v16 or higher)
• npm or yarn
• Playwright (installed automatically as a dependency)
• A Mon Marché account with valid credentials

   git clone https://github.com/Chopin85/mcp-server-monmarche
   cd mcp-server-monmarche
   

2. Install dependencies:
