Medusa MCP Server

medusa-mcp

Overview

medusa-mcp is a Model Context Protocol (MCP) server designed for integration with the Medusa JavaScript SDK. It provides a scalable backend layer for managing and interacting with Medusa’s data models, enabling automation, orchestration, and intelligent service extensions.

🧩 What is an MCP Server?

An MCP server is a modular, extensible backend that:

• Enables real-time service orchestration
• Supports standardized, high-throughput communication
• Acts as a bridge between AI/automation tools and real-world systems

These servers are used in areas like AI, IoT, and enterprise software to connect various services and automate tasks using standardized protocols like JSON-RPC.

🔑 Key Features

• Modular Architecture – Composable services for flexibility
• High Efficiency – Optimized for speed and scale
• Extensible Design – Add new capabilities easily
• Cross-Environment Deployment – Cloud, on-prem, or hybrid
• AI-Ready Interfaces – Integrate LLMs and tools seamlessly

🧠 Role in AI Systems

MCP servers allow AI agents to:

• Access real-time data from APIs, files, or databases
• Automate business processes (e.g., order fulfillment, pricing updates)
• Interact with external services in a secure and controlled way

🚀 Medusa JS + MCP

Using medusa-mcp, Medusa JS can:

• Automate workflows (e.g., inventory or pricing adjustments)
• Connect with external tools (email, analytics, etc.)
• Use AI agents to analyze trends and trigger actions
• Enable scalable, modular architecture for commerce platforms

✨ Features

• ✅ Model Context Protocol (MCP) support
• 📈 Scalable infrastructure
• 🧱 Extensible plugin architecture
• 🔗 Integrated with Medusa JS SDK

Here's how the medusa-mcp server fits into a typical setup with Medusa JS and external systems:

🧪 Customization

To tailor the server to your Medusa setup:

Replace admin.json and store.json with your own OAS definitions for fine-grained control.

• Replace the OpenAPI schemas in the oas/ folder:
  • admin.json – Admin endpoints
  • store.json – Storefront endpoints

Use the @medusajs/medusa-oas-cli to regenerate these files.

You can also fork this project to build your own custom MCP-powered Medusa integration.
