Remote MCP Server Template [Early version]

This project provides a template for building a Model Context Protocol (MCP) server for commercetools Composable Commerce. The MCP server can be hosted on commercetools Connect and is designed to be easily configurable and extensible for various commerce use cases.

Overview

The MCP server acts as a servicable channel to AI agents that enables secure, flexible, and context-aware access to commercetools APIs. It supports both public and private authentication modes and allows fine-grained control over available tools and actions.

Features

• Configurable authentication: Supports both client_credentials and auth_token authentication.
• Tool-based access control: Enable or restrict API actions using the TOOLS configuration.
• Admin mode: Optionally allow resource creation and editing.
• Easy deployment: Ready to be hosted on commercetools Connect.

Configuration is managed via the connect.yaml file. Below is an explanation of each field:
