How to Set Up and Use Medusa MCP
Medusa MCP Server is a TypeScript-based Model Context Protocol server that integrates with the Medusa.js e-commerce platform via the official Medusa JavaScript SDK. It provides AI assistants with a programmatic interface to Medusa's data models, enabling automation of commerce workflows such as inventory management, order processing, and pricing updates. Teams building on Medusa can use this server to orchestrate backend operations through natural-language prompts without writing custom API integrations.
Prerequisites
- Node.js 18.x or higher
- A running Medusa backend instance (v2.x recommended)
- Medusa publishable API key and, for admin operations, admin credentials
- npm or yarn for dependency management
- An MCP-compatible client such as Claude Desktop

}Prompts to try
Use these prompts once the server is connected to interact with your Medusa store through Claude.
- "List all products in the Medusa store and show their prices."
- "Show me all pending orders that need fulfillment."
- "Update the inventory for product variant var_01 to 50 units."
- "Create a new product category called 'Summer Collection'."
- "What are the current shipping options available in the store?"Troubleshooting Medusa MCP
Connection refused when the server tries to reach the Medusa backend
Ensure your Medusa backend is running and that MEDUSA_BACKEND_URL is correct. By default Medusa runs on http://localhost:9000. Check with: curl http://localhost:9000/health
Authentication fails with 401 Unauthorized on admin operations
Verify that MEDUSA_USERNAME and MEDUSA_PASSWORD match a valid Medusa admin user. You can test credentials directly via the Medusa admin dashboard or REST API.
'Cannot find module dist/index.js' error when starting the server
The TypeScript source must be compiled before running. Execute 'npm run build' inside the medusa-mcp directory to generate the dist/ folder.
