How to Connect to Live Cosmos DB Data from Gemini CLI (via CData Connect AI)

Gemini CLI is a command-line interface tool that provides direct access to Google's Gemini AI models for code generation, text analysis, and conversational AI capabilities. When combined with CData Connect AI Remote MCP, you can leverage Gemini CLI to interact with your Cosmos DB data in real-time through natural language queries. This article outlines the process of connecting to Cosmos DB using Connect AI Remote MCP and configuring Gemini CLI to interact with your Cosmos DB data.

CData Connect AI offers a dedicated cloud-to-cloud interface for connecting to Cosmos DB data. The CData Connect AI Remote MCP Server enables secure communication between Gemini CLI and Cosmos DB. This allows you to ask questions and take actions on your Cosmos DB data using natural language through Gemini CLI, all without the need for data replication to a natively supported database. With its inherent optimized data processing capabilities, CData Connect AI efficiently channels all supported SQL operations, including filters and JOINs, directly to Cosmos DB. This leverages server-side processing to swiftly deliver the requested Cosmos DB data.

In this article, we show how to configure Gemini CLI to conversationally explore (or Vibe Query) your data using natural language. With Connect AI you can query and interact with live Cosmos DB data, plus hundreds of other sources.

Step 1: Configure Cosmos DB Connectivity for Gemini CLI

Connectivity to Cosmos DB from Gemini CLI is made possible through CData Connect AI Remote MCP. To interact with Cosmos DB data from Gemini CLI, we start by creating and configuring a Cosmos DB connection in CData Connect AI.

1. Log into Connect AI, click Sources, and then click Add Connection

2. Select "Cosmos DB" from the Add Connection panel

3. Enter the necessary authentication properties to connect to Cosmos DB.

   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.
   
4. Click Save & Test
5. Navigate to the Permissions tab in the Add Cosmos DB Connection page and update the User-based permissions.

Add a Personal Access Token

A Personal Access Token (PAT) is used to authenticate the connection to Connect AI from Gemini CLI. It is best practice to create a separate PAT for each service to maintain granularity of access.

1. Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
2. On the Settings page, go to the Access Tokens section and click Create PAT.
3. Give the PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured and a PAT generated, we are ready to connect to Cosmos DB data from Gemini CLI.

Step 2: Configure Gemini CLI for CData Connect AI

Follow these steps to configure Gemini CLI to connect to CData Connect AI:

1. Ensure Gemini CLI is installed on your system. If not, install it using npm:

   npm install -g @google-gemini/cli

2. Locate your Gemini CLI settings file. If the file doesn't exist, create it:
   • Linux/Unix/Mac: ~/.gemini/settings.json
   • Windows: %USERPROFILE%\.gemini\settings.json
3. Add the CData Connect AI Remote MCP Server to the mcpServers object in your settings file. Replace YOUR_EMAIL and YOUR_PAT with your Connect AI email address and the PAT created previously:

   {
     "mcpServers": {
       "cdata-connect-cloud": {
         "httpUrl": "https://mcp.cloud.cdata.com/mcp",
         "headers": {
           "Authorization": "Basic YOUR_EMAIL:YOUR_PAT"
         }
       }
     }
   }    

   For example, if your email is [email protected] and your PAT is Uu90pt5vEO..., the Authorization header would be:

   "Authorization": "Basic [email protected]:Uu90pt5vEO..."

4. Save the settings file. Gemini CLI will now use the CData Connect AI MCP Server for data operations.

Step 3: Query Live Cosmos DB Data with Natural Language

With Gemini CLI configured and connected to CData Connect AI, you can now interact with your Cosmos DB data using natural language queries. The MCP integration allows you to ask questions and receive responses from the Cosmos DB data source in real-time.

Start using Gemini CLI to explore your data:

1. Open your terminal and start a Gemini CLI session:

   gemini

2. You can now use natural language to query your Cosmos DB data. For example:
   • "Show me all customers from the last 30 days"
   • "What are my top performing products?"
   • "Analyze sales trends for Q4"
   • "List all active projects with their current status"
3. Gemini CLI will automatically translate your natural language queries into appropriate SQL queries and execute them against your Cosmos DB data through the CData Connect AI MCP Server.

The combination of Gemini CLI's natural language processing capabilities and CData Connect AI's robust data connectivity enables you to explore and analyze your Cosmos DB data without writing complex SQL queries or needing deep technical knowledge of the underlying data structure.
