Overview

What is Azure Cosmos DB MCP Client & Server?

This project demonstrates how to build an MCP Server and client connected to Azure Cosmos DB for NoSQL.

FAQ from Azure Cosmos DB MCP Client & Server

What Azure services are required?

Azure Cosmos DB for NoSQL (with vector search enabled), Azure Blob Storage for images, and Azure OpenAI for embeddings.

How do I populate the product catalog?

Run the .NET console application in the populate folder after configuring appsettings.json with your Cosmos DB account details and after authenticating with Azure (az login).

Where does data live?

Product, cart, and order data is stored in Azure Cosmos DB containers. Product images are hosted in Azure Blob Storage.

What authentication is used?

The project uses Azure RBAC (role-based access control) with an app registration and client secret. It also requires a storage account role assignment (Storage Blob Data Contributor). No built-in user authentication is implemented; the user email is hardcoded in nextjs/models/constants.ts.
