Build Cosmos DB-Powered Applications in GitHub Copilot with CData Code Assist MCP

GitHub Copilot is an AI-powered coding assistant that integrates directly into Visual Studio Code and other IDEs. With support for MCP, GitHub Copilot can connect to local tools and enterprise data sources, enabling natural language interaction with live systems during development.

Model Context Protocol (MCP) is an open standard for connecting LLM clients to external services through structured tool interfaces. MCP servers expose capabilities such as schema discovery and live querying, allowing AI agents to retrieve and reason over real-time data safely and consistently.

In this article, we guide you through installing the CData Code Assist MCP for Cosmos DB, configuring the connection to Cosmos DB, connecting the Code Assist MCP add-on to GitHub Copilot, and querying live Cosmos DB data from within Visual Studio Code.

Prerequisites

• Visual Studio Code is installed on your machine
• GitHub Copilot Chat extension is enabled in Visual Studio Code
• CData Code Assist MCP for Cosmos DB has been installed

Step 1: Download and install the CData Code Assist MCP for Cosmos DB

1. To begin, download the CData Code Assist MCP for Cosmos DB
2. Find and double-click the installer to begin the installation
3. Run the installer and follow the prompts to complete the installation

When the installation is complete, you are ready to configure your Code Assist MCP add-on by connecting to Cosmos DB.

Step 2: Configure the connection to Cosmos DB

1. After installation, open the CData Code Assist MCP for Cosmos DB configuration wizard

   NOTE: If the wizard does not open automatically, search for "CData Code Assist MCP for Cosmos DB" in the Windows search bar and open the application.

   
2. In MCP Configuration > Configuration Name, either select an existing configuration or choose to create a new one
3. Name the configuration (e.g. "cdata_cosmosdb") and click OK

4. Enter the appropriate connection properties in the configuration wizard

   To obtain the connection string needed to connect to a Cosmos DB account using the SQL API, log in to the Azure Portal, select Azure Cosmos DB, and select your account. In the Settings section, click Connection String and set the following values:

   • AccountEndpoint: The Cosmos DB account URL from the Keys blade of the Cosmos DB account
   • AccountKey: In the Azure portal, navigate to the Cosmos DB service and select your Azure Cosmos DB account. From the resource menu, go to the Keys page. Find the PRIMARY KEY value and set AccountKey to this value.
   
5. Click Connect to authenticate with Cosmos DB
6. Click Save & Test to finalize the connection

This process creates a .mcp configuration file that GitHub Copilot will reference when launching the Code Assist MCP add-on. Now with your Code Assist MCP add-on configured, you are ready to connect it to GitHub Copilot.

Step 3: Connect the Code Assist MCP add-on to GitHub Copilot

1. Download and install Visual Studio Code and enable the GitHub Copilot Chat extension

Option 1: Manually add the MCP configuration

1. Open or create the mcp.json file:
   • For global configuration: %%APPDATA%%/Roaming/Code/User/mcp.json
   • For project-specific configuration: /.vscode/mcp.json
2. Add the JSON code shown below and save the file

{
  "servers": {
    "cdata_cosmosdb": {
      "command": "C:\Program Files\CData\CData Code Assist MCP for Cosmos DB\jre\bin\java.exe",
      "args": [
        "-Dfile.encoding=UTF-8",
        "-jar",
        "C:\Program Files\CData\CData Code Assist MCP for Cosmos DB\lib\cdata.mcp.cosmosdb.jar",
        "cdata_cosmosdb"
      ]
    }
  }
}

NOTE: The command value should point to your Java 17+ java.exe executable, and the JAR path should point to the installed CData Code Assist MCP add-on .jar file. The final argument must match the MCP configuration name you saved in the CData configuration wizard (e.g. "cdata_cosmosdb").

Option 2: Copy the MCP configuration from the CData Code Assist MCP for Cosmos DB UI

1. After saving and testing your connection in the configuration wizard, click Next
2. Select Github Copilot from the AI MCP Tool dropdown
3. Follow the MCP Client Instructions to create the required configuration file
4. Copy the displayed JSON code and paste it into your configuration file

Step 4: Query live Cosmos DB data in GitHub Copilot

1. Launch Visual Studio Code and open the GitHub Copilot Chat interface. Select the tool icon to enable the configured Code Assist MCP add-on
2. Ask questions about your Cosmos DB data using natural language. For example:

   "List all tables available in my Cosmos DB data data connection."

   
3. Start building with natural language prompts:

   For my project, data from the Customers is very important. Pull data from the most important columns like City and CompanyName.
   

GitHub Copilot is now fully integrated with CData Code Assist MCP for Cosmos DB and can use the MCP tools to explore schemas and execute live queries against Cosmos DB.

Build with Code Assist MCP. Deploy with CData Drivers.

Download Code Assist MCP for free and give your AI tools schema-aware access to live Cosmos DB data during development. When you're ready to move to production, CData Cosmos DB Drivers deliver the same SQL-based access with enterprise-grade performance, security, and reliability.
