Shopify Dev MCP Server

This project implements a Model Context Protocol (MCP) server that interacts with Shopify Dev. This protocol supports various tools to interact with different Shopify APIs. At the moment the following APIs are supported:

Admin GraphQL API
Functions
(Optional) Polaris Web Components

Setup

To run the Shopify MCP server using npx, use the following command:

npx -y @shopify/dev-mcp@latest

Usage with Cursor or Claude Desktop

Add the following configuration. For more information, read the Cursor MCP documentation or the Claude Desktop MCP guide.

{
  "mcpServers": {
    "shopify-dev-mcp": {
      "command": "npx",
      "args": ["-y", "@shopify/dev-mcp@latest"]
    }
  }
}

On Windows, you might need to use this alternative configuration:

{
  "mcpServers": {
    "shopify-dev-mcp": {
      "command": "cmd",
      "args": ["/k", "npx", "-y", "@shopify/dev-mcp@latest"]
    }
  }
}

Disable instrumentation

In order to better understand how to improve the MCP server, this package makes instrumentation calls. In order to disable them you can set the OPT_OUT_INSTRUMENTATION environment variable. In Cursor or Claude Desktop the configuration would look like this:

{
  "mcpServers": {
    "shopify-dev-mcp": {
      "command": "npx",
      "args": ["-y", "@shopify/dev-mcp@latest"],
      "env": {
        "OPT_OUT_INSTRUMENTATION": "true"
      }
    }
  }
}

Opt-in Polaris support (experimental)

If you want Cursor or Claude Desktop to surface Polaris Web Components documentation, include an env block with the POLARIS_UNIFIED flag in your MCP server configuration:

{
  "mcpServers": {
    "shopify-dev-mcp": {
      "command": "npx",
      "args": ["-y", "@shopify/dev-mcp@latest"],
      "env": {
        "POLARIS_UNIFIED": "true"
      }
    }
  }
}
