Use the CData Code Assist MCP for Microsoft Dataverse to explore live Microsoft Dataverse Data in Gemini Code Assist to assist with building Microsoft Dataverse-powered applications.

Gemini Code Assist is an AI-powered coding companion that integrates intelligent code generation into everyday development workflows. With support for MCP, Gemini Code Assist can connect to live enterprise data sources directly from Visual Studio Code, enabling natural language interaction with structured data without switching context or manually writing data access code.

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.

This guide walks through installing the CData Code Assist MCP for Microsoft Dataverse, configuring the connection to Microsoft Dataverse, connecting the Code Assist MCP add-on to Gemini Code Assist, and querying live Microsoft Dataverse data from within the editor.

About Microsoft Dataverse Data Integration

CData provides the easiest way to access and integrate live data from Microsoft Dataverse (formerly the Common Data Service). Customers use CData connectivity to:

  • Access both Dataverse Entities and Dataverse system tables to work with exactly the data they need.
  • Authenticate securely with Microsoft Dataverse in a variety of ways, including Azure Active Directory, Azure Managed Service Identity credentials, and Azure Service Principal using either a client secret or a certificate.
  • Use SQL stored procedures to manage Microsoft Dataverse entities - listing, creating, and removing associations between entities.

CData customers use our Dataverse connectivity solutions for a variety of reasons, whether they're looking to replicate their data into a data warehouse (alongside other data sources)or analyze live Dataverse data from their preferred data tools inside the Microsoft ecosystem (Power BI, Excel, etc.) or with external tools (Tableau, Looker, etc.).


Getting Started


Prerequisites

Before starting, ensure the following requirements are met:

  1. Visual Studio Code is installed on the machine
  2. Gemini Code Assist extension is enabled in Visual Studio Code
  3. CData Code Assist MCP for Microsoft Dataverse has been installed
  4. Access to Microsoft Dataverse

Note: Gemini Code Assist must already be set up and functional in Visual Studio Code before configuring MCP servers. MCP servers are accessed when Gemini Code Assist is running in Agent mode.

Step 1: Download and install the CData Code Assist MCP for Microsoft Dataverse

  1. To begin, download the CData Code Assist MCP for Microsoft Dataverse
  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, the Code Assist MCP add-on is ready for configuration by connecting to Microsoft Dataverse.

Step 2: Configure the connection to Microsoft Dataverse

  1. After installation, open the CData Code Assist MCP for Microsoft Dataverse configuration wizard

    NOTE: If the wizard does not open automatically, search for "CData Code Assist MCP for Microsoft Dataverse" 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_cds") and click OK
  4. Enter the appropriate connection properties in the configuration wizard

    You can connect without setting any connection properties for your user credentials. Below are the minimum connection properties required to connect.

    • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
    • OrganizationUrl: Set this to the organization URL you are connecting to, such as https://myorganization.crm.dynamics.com.
    • Tenant (optional): Set this if you wish to authenticate to a different tenant than your default. This is required to work with an organization not on your default Tenant.

    When you connect the Common Data Service OAuth endpoint opens in your default browser. Log in and grant permissions. The OAuth process completes automatically.

  5. Click Connect to authenticate with Microsoft Dataverse through OAuth
  6. Then, click Save Configuration to save the Code Assist MCP add-on

This process creates a .mcp configuration file that Gemini Code Assist will reference when launching the Code Assist MCP add-on. With the Code Assist MCP add-on configured, it is ready to connect to Gemini Code Assist.

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

  1. Ensure Visual Studio Code is installed and the Gemini Code Assist extension is enabled
  2. From the configuration wizard, click Next after saving and testing the connection
  3. Select Gemini Code Assist from the AI MCP Tool dropdown
  4. Click Copy JSON to copy the generated MCP configuration to the clipboard
  5. Paste the copied JSON into the appropriate configuration file based on the desired scope:
    • User-level: Configuration applies across all projects for the current user
    • Workspace-level: Configuration applies only to the current workspace or project

    NOTE: The configuration includes the path to Java 17+ executable and the CData Code Assist MCP add-on JAR file. The final argument must match the MCP configuration name saved in the wizard (e.g. "cdata_cds").

  6. Save the configuration file and restart Visual Studio Code if necessary

Step 4: Query live Microsoft Dataverse data in Gemini Code Assist

  1. Open Visual Studio Code and select Gemini Code Assist in the activity bar
  2. Enter /mcp in the chat prompt to verify the connection status. The Microsoft Dataverse Code Assist MCP add-on should appear with a green connection indicator
  3. Ask questions about Microsoft Dataverse data using natural language. For example:
    "Provide the list of all tables available in my Microsoft Dataverse data connection."
  4. Generate code that works with live Microsoft Dataverse data. For example:
    "Write a function to retrieve records from the Accounts table where AccountId matches a given value."

Gemini Code Assist is now fully integrated with the CData Code Assist MCP add-on and can use the MCP tools exposed to explore schemas, execute live queries against Microsoft Dataverse, and generate data-aware code.
