Build AlloyDB-Powered Applications in Cursor with CData Code Assist MCP

Cursor is an AI-powered code editor that integrates agentic AI into everyday development workflows. With support for MCP, Cursor can connect to local tools and enterprise data sources directly from the editor, enabling natural language interaction with live systems without switching context.

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 AlloyDB, configuring the connection to AlloyDB, connecting the Code Assist MCP add-on to Cursor, and querying live AlloyDB data from within the editor.

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

1. To begin, download the CData Code Assist MCP for AlloyDB
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 AlloyDB.

Step 2: Configure the connection to AlloyDB

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

   NOTE: If the wizard does not open automatically, search for "CData Code Assist MCP for AlloyDB" 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_alloydb") and click OK

4. Enter the appropriate connection properties in the configuration wizard

   The following connection properties are usually required in order to connect to AlloyDB.

   • Server: The host name or IP of the server hosting the AlloyDB database.
   • User: The user which will be used to authenticate with the AlloyDB server.
   • Password: The password which will be used to authenticate with the AlloyDB server.

   You can also optionally set the following:

   • Database: The database to connect to when connecting to the AlloyDB Server. If this is not set, the user's default database will be used.
   • Port: The port of the server hosting the AlloyDB database. This property is set to 5432 by default.

   Authenticating with Standard Authentication

   Standard authentication (using the user/password combination supplied earlier) is the default form of authentication.

   No further action is required to leverage Standard Authentication to connect.

   Authenticating with pg_hba.conf Auth Schemes

   There are additional methods of authentication available which must be enabled in the pg_hba.conf file on the AlloyDB server.

   Find instructions about authentication setup on the AlloyDB Server here.

   Authenticating with MD5 Authentication

   This authentication method must be enabled by setting the auth-method in the pg_hba.conf file to md5.

   Authenticating with SASL Authentication

   This authentication method must be enabled by setting the auth-method in the pg_hba.conf file to scram-sha-256.

   Authenticating with Kerberos

   The authentication with Kerberos is initiated by AlloyDB Server when the ∏ is trying to connect to it. You should set up Kerberos on the AlloyDB Server to activate this authentication method. Once you have Kerberos authentication set up on the AlloyDB Server, see the Kerberos section of the help documentation for details on how to authenticate with Kerberos.

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

This process creates a .mcp configuration file that Cursor 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 Cursor.

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

1. Download the Cursor desktop application and complete the sign-up flow for your account
2. From the top menu, click Settings to open the settings panel
3. In the left navigation, open the Tools & MCP tab and click Add Custom MCP

Option 1: Manually add the MCP configuration

1. Cursor opens an mcp.json file in the editor
2. Add the code shown below and save the file

{
  "mcpServers": {
    "cdata-local": {
      "command": "C:/Program Files/Java/jdk-17/bin/java.exe",
      "args": [
        "-jar",
        "C:/Program Files/CData/CData Code Assist MCP for AlloyDB/lib/cdata.mcp.alloydb.jar",
        "cdata_alloydb"
      ]
    }
  }
}



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_alloydb").

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

1. After saving and testing your connection in the configuration wizard, click Next

2. Select Cursor from the AI MCP Tool dropdown

3. Follow the MCP Client Instructions to create the required folders for the MCP config

4. Copy the displayed JSON code and paste it into your configuration file
5. In Cursor, open the project folder you created with the mcp.json config
4. The Code Assist MCP add-on should appear as Running under Installed MCP Servers

Step 4: Query live AlloyDB data in Cursor

1. From the top bar, click Toggle AI Pane to open the chat window
2. Ask questions about your AlloyDB data using natural language. For example:

   "List all tables available in my AlloyDB data connection."

   

Cursor is now fully integrated with CData Code Assist MCP for AlloyDB and can use the MCP tools exposed to explore schemas and execute live queries against AlloyDB.
