MCP Server for Azure Cosmos DB using the JavaScript SDK

This is an implementation of a Model Context Protocol (MCP) server for Azure Cosmos DB using the Azure Cosmos Javascript SDK. It exposes a set of tools for interacting with Cosmos DB through an LLM or agent using the MCP standard.

Quick Example

You: "What were our top 10 customers last month?"
Claude: *queries your Azure Cosmos DB database and gives you the answer in plain English*

How Does It Work? 🛠️

This server leverages the Model Context Protocol (MCP), a versatile framework that acts as a universal translator between AI models and databases. Although MCP is built to support any AI model, it is currently accessible as a developer preview in Claude Desktop.

Here's all you need to do:

1. Set up project (see below)
2. Add your project details to Claude Desktop's config file
3. Start chatting with your Azure Cosmos DB data naturally!

What Can It Do? 📊

• Run Azure Cosmos DB queries by just asking questions in plain English

Quick Start 🚀

Prerequisites

• Node.js 14 or higher
• Azure Cosmos DB NOSQL account or Azure Cosmos DB Emulator with the sample dataset(./dataset/vehciles) inserted
• Claude Desktop

Set up project

Obtain the Azure Cosmos DB NoSQL account URI and KEY from the Keys section, and the Database ID and Container ID from the Data Explorer section, then create a .env file with the following keys, replacing the placeholder values with your own:

COSMOSDB_URI=
COSMOSDB_KEY=
COSMOS_DATABASE_ID=
COSMOS_CONTAINER_ID=

Getting Started

1. Install Dependencies
   Run the following command in the root folder to install all necessary dependencies:

   npm install

2. Build the Project
   Compile the project by running:

   npm run build

3. Start the Server
   Navigate to the dist folder and start the server:

   npm start

4. Confirmation Message
   You should see the following message:

   Azure Cosmos DB Server running on stdio

How to run it using VSCODE Insiders

To use the Azure MCP with VS Code Insiders with GitHub Copilot Agent Mode, follow these instructions:

1. Install VS Code Insiders.

2. Install the pre-release versions of the GitHub Copilot and GitHub Copilot Chat extensions in VS Code Insiders.

3. Open a new instance of VS Code Insiders in an empty folder.

4. Copy the mcp.json file from this repo to your new folder, and update the values to match your environment.

5. Open GitHub Copilot and switch to Agent mode. You should see Azure Cosmos DB MCP Server in the list of tools.

6. Try a prompt that tells the agent to use the Azure MCP server, such as "List Vehicles".

7. The agent should be able to use the Azure Cosmos DB MCP server to complete your query.

This setup allows you to seamlessly interact with Azure Cosmos DB through the MCP server in VSCODE with Github Copilot as shown below.

Add your project details to Claude Destkop's config file

Open Claude Desktop and Navigate to File -> Settings -> Developer -> Edit Config and open the claude_desktop_config file and replace with the values below,

{
  "mcpServers": {
    "cosmosdb": {
      "command": "node",
      "args": [ "C:/Cosmos/azure-cosmos-mcp/dist/index.js" ] // Your Path for the Azure Cosmos DB MCP server file,
      "env": {
        "COSMOSDB_URI": "Your Cosmos DB Account URI",
        "COSMOSDB_KEY": "Your Cosmos DB KEY",
        "COSMOS_DATABASE_ID": "Your Database ID",
        "COSMOS_CONTAINER_ID": "Vehicles"
      }
    }
  }
}

You should now have successfully configured the MCP server for Azure Cosmos DB with Claude Desktop. This setup allows you to seamlessly interact with Azure Cosmos DB through the MCP server as shown below.
