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

🧪 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.
