Build Oracle Eloqua Reporting-Powered Applications in Claude Code with CData Code Assist MCP

Claude Code is an AI-powered command line tool that enables agentic coding workflows. With support for MCP, Claude Code can connect to local tools and enterprise data sources directly from your terminal, 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.

The following steps cover installing the CData Code Assist MCP for Oracle Eloqua Reporting, configuring the connection to Oracle Eloqua Reporting, connecting the Code Assist MCP add-on to Claude Code, and querying live Oracle Eloqua Reporting data from within the terminal.

Step 1: Download and install the CData Code Assist MCP for Oracle Eloqua Reporting

1. To begin, download the CData Code Assist MCP for Oracle Eloqua Reporting 👁 Downloading the CData Code Assist MCP add-on installer
   
2. Find and double-click the installer to begin the installation
3. Run the installer and follow the prompts to complete the installation 👁 Completing the CData Code Assist MCP add-on installation
   

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

Step 2: Configure the connection to Oracle Eloqua Reporting

1. After installation, open the CData Code Assist MCP for Oracle Eloqua Reporting configuration wizard 👁 The CData Code Assist MCP add-on configuration wizard
   

   NOTE: If the wizard does not open automatically, search for "CData Code Assist MCP for Oracle Eloqua Reporting" 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 👁 Creating a new configuration
   
3. Name the configuration (e.g. "cdata_oracleeloquareporting") and click OK 👁 Naming the configuration
   

4. Enter the appropriate connection properties in the configuration wizard

   Oracle Eloqua Reporting supports the following authentication methods:

   • Basic authentication (User and Password)
   • OAuth 2.0 code grant flow
   • OAuth 2.0 password grant flow

   Basic Authentication (User and Password)

   To perform authentication with a user and password, specify these properties:

   • AuthScheme: Basic.
   • Company: The company name associated with your Oracle Eloqua Reporting account.
   • User: Your login account name.
   • Password: Your login password.

   OAuth Authentication (Code Grant Flow)

   To authenticate with the OAuth code grant flow, you must set AuthScheme to OAuth and create a custom OAuth application. For information about how to create a custom OAuth application, see the Help documentation.

   Then set the following properties:

   • InitiateOAuth: GETANDREFRESH. Used to automatically get and refresh the OAuthAccessToken.
   • OAuthClientId: The client Id assigned when you registered your application.
   • OAuthClientSecret: The client secret that was assigned when you registered your application.
   • CallbackURL: The redirect URI that was defined when you registered your application.

   When you connect, the driver opens Oracle Eloqua Reporting's OAuth endpoint in your default browser. Log in and grant permissions to the application. When the access token expires, the driver refreshes it automatically.

   OAuth Authentication (Password Grant Flow)

   With the OAuth password grant flow, you can use your OAuth application's credentials alongside your user credentials to authenticate without the need to grant permission manually via a browser prompt. You must create an OAuth app (see the Help documentation) to use this authentication method.

   Set the following properties:

   • AuthScheme: OAuthPassword
   • Company: The company's unique identifier.
   • User: Your login account name.
   • Password: Your login password.
   • OAuthClientId: The client Id assigned when you registered your custom OAuth application.
   • OAuthClientSecret: The client secret assigned when you registered your custom OAuth application.

5. Click Connect to authenticate with Oracle Eloqua Reporting
6. Then, click Save Configuration to save the Code Assist MCP add-on 👁 Saving the Code Assist MCP add-on configuration
   

This process creates a .mcp configuration file that Claude Code 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 Claude Code.

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

1. Install the Claude Code CLI using the terminal
2. Open the Claude Code configuration file at ~/.config/claude-code/config.json (or the location shown after initialization)

Option 1: Manually add the MCP configuration

1. Open the mcp.json file in your preferred editor
2. Add the code shown below

{
"mcpServers" : {
 "cdata_oracleeloquareporting" : {
 "type" : "stdio",
 "command" : "C:\Program Files\CData\CData Code Assist MCP for Oracle Eloqua Reporting\jre\bin\java.exe",
 "args" : [ "-Dfile.encoding=UTF-8", "-jar", "C:\Program Files\CData\CData Code Assist MCP for Oracle Eloqua Reporting/lib/cdata.mcp.oracleeloquareporting.jar", "cdata_oracleeloquareporting" ], 
 "env" : {}
 }
}
}

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_oracleeloquareporting").

Option 2: Copy the MCP configuration from the CData Code Assist MCP for Oracle Eloqua Reporting UI

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

2. Select Claude Code from the AI MCP Tool dropdown
👁 Choosing the required AI MCP tool

3. Click Copy JSON to copy the generated MCP configuration to your clipboard
👁 Copying the MCP configuration

4. Paste the copied JSON into the mcp.json file

Step 4: Verify connection in Claude Code

Claude Code provides tools to verify the connection is active before building.

1. Open a terminal and navigate to your project directory. Run the command claude mcp list
2. Check that your configuration name appears with a Connected status
👁 Checking the connection status

3. Start Claude Code by running claude
4. Inside the Claude Code session, type /mcp to view active servers 👁 Viewing active MCP servers
   

Step 5: Query live Oracle Eloqua Reporting data in Claude Code

With the connection verified, you can now use natural language prompts to query and work with live Oracle Eloqua Reporting data.

1. Prompt Claude Code to review the instructions for your MCP connection to ensure it has all the appropriate context when writing code 👁 Reviewing MCP connection instructions
   
2. Start building with natural language prompts! For example:

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

Claude Code will use the MCP add-on to connect to Oracle Eloqua Reporting, retrieve the requested data, and provide results directly in your terminal
