Demo Shopify Storefront

You can run a multi-store Shopify MCP server to access store data and perform actions like product searches, cart creation, and cart updates across several stores from one centralized MCP backend.

How to use

You interact with the server through an MCP client. For multi-store usage, you specify a storeId in your tool calls to target a particular Shopify store. The server exposes common shopping functions across stores, so you can switch between stores by changing the storeId parameter without restarting or reconfiguring the server.

Key store operations you can perform include listing configured stores, searching products within a single store, and managing a shopping cart. Each tool requires you to pass the storeId to indicate which store you are operating on.

How to install

Prerequisites you need before you install this MCP server:

• Node.js installed on your machine (recommended LTS version)
• npm installed with Node.js (npm is bundled with Node.js)

Step by step setup and run flow you can follow now:

# First, set up environment files for single or multi-store usage
cp .env.example .env
# or for multi-store setup
cp .env.stores.example .env

# Install dependencies
npm install

# Build the MCP server
npm run build

# Start the MCP server
npm start

Notes and tips

You can switch between stores by adjusting the storeId parameter in the tools you call. The server is designed to support multiple Shopify stores simultaneously, so you can configure several stores, each with its own credentials and display name, in the environment configuration.

Configuration and security

Prepare environment values for each store and for the global server configuration. You will typically provide the domain, Storefront API token, Admin API token (for advanced operations), and your app’s API key/secret. Guard these credentials and do not expose them in client-facing code or logs.
