Build NASA-Powered Applications in Gemini Code Assist with CData MCP Server

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 explains how to install the CData API Driver for MCP Server, configure the connection to NASA, connect the MCP Server add-on to Gemini Code Assist, and query live NASA data from within the editor.

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 API Driver for MCP Server has been installed
4. Access to NASA

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 API Driver for MCP Server

1. To begin, download the CData API Driver for MCP Server 👁 Downloading the CData MCP Server 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 MCP Server add-on installation
   

When the installation is complete, the MCP Server add-on is ready for configuration by connecting to NASA.

Step 2: Configure the connection to NASA

1. After installation, open the CData API Driver for MCP Server configuration wizard 👁 The CData MCP Server add-on configuration wizard
   

   NOTE: If the wizard does not open automatically, search for "CData API Driver for MCP Server" 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_api") and click OK 👁 Naming the configuration
   

4. Enter the appropriate connection properties in the configuration wizard

   Using API Key Authentication

   Most NASA API endpoints (APOD, NeoWS, DONKI, TechTransfer) require a NASA API key. Register for a free key at https://api.nasa.gov. The default DEMO_KEY provides limited access (30 requests/hour, 50 requests/day); a registered key allows 1,000 requests/hour.

   The following endpoints do not require an API key and work without authentication: EONET (Earth Observatory Natural Event Tracker), EPIC (Earth Polychromatic Imaging Camera), NASA Image and Video Library, and TechPort.

   After obtaining your API key, set the following connection properties:

   • AuthScheme: Set this to APIKey.
   • APIKey: Set this to your NASA API key. Use DEMO_KEY for limited testing.

   Example Connection String

   Profile=C:\profiles\NASA.apip;AuthScheme=APIKey;APIKey=YOUR_NASA_API_KEY
   

   Connecting to NASA

   Once the authentication is configured, you can connect to NASA and query data from any of the available tables such as AstronomyPictureOfDay, NearEarthObjectFeed, EonetEvents, and NasaImageLibrary.

5. Click Connect to authenticate with NASA
6. Then, click Save Configuration to save the MCP Server add-on 👁 Saving the MCP Server add-on configuration
   

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

Step 3: Connect the MCP Server 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 👁 Selecting 'Next'
   
3. Select Gemini Code Assist from the AI MCP Tool dropdown 👁 Choosing Gemini Code Assist as the AI MCP tool
   
4. Click Copy JSON to copy the generated MCP configuration to the clipboard 👁 Copying the MCP configuration
   
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 MCP Server add-on JAR file. The final argument must match the MCP configuration name saved in the wizard (e.g. "cdata_api").

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

Step 4: Query live NASA data in Gemini Code Assist

1. Open Visual Studio Code and select Gemini Code Assist in the activity bar 👁 Open Gemini Code Assist
   
2. Enter /mcp in the chat prompt to verify the connection status. The NASA MCP Server add-on should appear with a green connection indicator 👁 Verify the connection status
   
3. Ask questions about NASA data using natural language. For example:

   "Provide the list of all tables available in my NASA data connection."

   👁 Querying live data from Gemini Code Assist
   
4. Generate code that works with live NASA data. For example:

   "Write a function to retrieve records from the AstronomyPictureOfDay table where matches a given value."

   👁 Generating function for live data from Gemini Code Assist
   

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