How to Connect to Live CSV Data from Google ADK Agents (via CData Connect AI)

Google ADK (Agent Development Kit) is a powerful, model-agnostic framework for building AI agents that can interact with various data sources and services. When combined with CData Connect AI Remote MCP, you can leverage Google ADK to build intelligent agents that interact with your CSV data in real-time through natural language queries. This article outlines the process of connecting to CSV using Connect AI Remote MCP and configuring a Google ADK agent to interact with your CSV data through ADK Web.

CData Connect AI offers a dedicated cloud-to-cloud interface for connecting to CSV data. The CData Connect AI Remote MCP Server enables secure communication between Google ADK agents and CSV. This allows your agents to read from and take actions on your CSV data, 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 CSV. This leverages server-side processing to swiftly deliver the requested CSV data.

In this article, we show how to configure a Google ADK agent to conversationally explore (or Vibe Query) your data using natural language. With Connect AI you can build agents with access to live CSV data, plus hundreds of other sources.

Step 1: Configure CSV Connectivity for Google ADK

Connectivity to CSV from Google ADK agents is made possible through CData Connect AI Remote MCP. To interact with CSV data from your ADK agent, we start by creating and configuring a CSV connection in CData Connect AI.

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

2. Select "CSV" from the Add Connection panel

3. Enter the necessary authentication properties to connect to CSV.

   Connecting to Local or Cloud-Stored (Box, Google Drive, Amazon S3, SharePoint) CSV Files

   CData Drivers let you work with CSV files stored locally and stored in cloud storage services like Box, Amazon S3, Google Drive, or SharePoint, right where they are.

   Setting connection properties for local files

   Set the URI property to local folder path.

   Setting connection properties for files stored in Amazon S3

   To connect to CSV file(s) within Amazon S3, set the URI property to the URI of the Bucket and Folder where the intended CSV files exist. In addition, at least set these properties:

   • AWSAccessKey: AWS Access Key (username)
   • AWSSecretKey: AWS Secret Key

   Setting connection properties for files stored in Box

   To connect to CSV file(s) within Box, set the URI property to the URI of the folder that includes the intended CSV file(s). Use the OAuth authentication method to connect to Box.

   Dropbox

   To connect to CSV file(s) within Dropbox, set the URI proprerty to the URI of the folder that includes the intended CSV file(s). Use the OAuth authentication method to connect to Dropbox. Either User Account or Service Account can be used to authenticate.

   SharePoint Online (SOAP)

   To connect to CSV file(s) within SharePoint with SOAP Schema, set the URI proprerty to the URI of the document library that includes the intended CSV file. Set User, Password, and StorageBaseURL.

   SharePoint Online REST

   To connect to CSV file(s) within SharePoint with REST Schema, set the URI proprerty to the URI of the document library that includes the intended CSV file. StorageBaseURL is optional. If not set, the driver will use the root drive. OAuth is used to authenticate.

   Google Drive

   To connect to CSV file(s) within Google Drive, set the URI property to the URI of the folder that includes the intended CSV file(s). Use the OAuth authentication method to connect and set InitiateOAuth to GETANDREFRESH.

   
4. Click Save & Test
5. Navigate to the Permissions tab in the Add CSV 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 your Google ADK agent. 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 CSV data from your Google ADK agent.

Step 2: Configure Your Google ADK Agent for CData Connect AI

Follow these steps to configure your Google ADK agent to connect to CData Connect AI. You can use our pre-built agent as a starting point, available at https://github.com/CDataSoftware/adk-mcp-client, or follow the instructions below to create your own.

1. Ensure you have the Google ADK Python SDK installed. If not, install it using pip:

   pip install google-genkit google-adk

2. Create or update your agent's configuration file (typically agent.py) to include the CData Connect AI MCP connection. You'll need to configure the MCP toolset with your Connect AI credentials.
3. Set up your environment variables or configuration for the MCP server connection. Create a .env file in your project root with the following variables:

   MCP_SERVER_URL=https://mcp.cloud.cdata.com/mcp
   MCP_USERNAME=YOUR_EMAIL
   MCP_PASSWORD=YOUR_PAT
       

   Replace YOUR_EMAIL with your Connect AI email address and YOUR_PAT with the Personal Access Token created in Step 1.
4. Configure your agent.py file to use the CData Connect AI MCP Server. Here's an example configuration:

   import os
   import base64
   from google.adk.agents import LlmAgent
   from google.adk.tools.mcp_tool.mcp_toolset import MCPToolset
   from google.adk.tools.mcp_tool.mcp_session_manager import StreamableHTTPConnectionParams
   from dotenv import load_dotenv
   
   # Load environment variables
   load_dotenv()
   
   # Get configuration from environment
   MCP_SERVER_URL = os.getenv('MCP_SERVER_URL', 'https://mcp.cloud.cdata.com/mcp')
   MCP_USERNAME = os.getenv('MCP_USERNAME', '')
   MCP_PASSWORD = os.getenv('MCP_PASSWORD', '')
   
   # Create auth header for MCP server
   auth_header = {}
   if MCP_USERNAME and MCP_PASSWORD:
       credentials = f"{MCP_USERNAME}:{MCP_PASSWORD}"
       auth_header = {"Authorization": f"Basic {base64.b64encode(credentials.encode()).decode()}"}
   
   # Define your agent with CData MCP tools
   root_agent = LlmAgent(
       model='gemini-2.0-flash-exp',  # You can use any supported model
       name='data_query_assistant',
       instruction="""You are a data query assistant with access to CSV data through CData Connect AI.
       
       You can help users explore and query their CSV data in real-time.
       Use the available MCP tools to:
       - List available databases and schemas
       - Explore table structures
       - Execute SQL queries
       - Provide insights about the data
       
       Always explain what you're doing and format results clearly.""",
       
       tools=[
           MCPToolset(
               connection_params=StreamableHTTPConnectionParams(
                   url=MCP_SERVER_URL,
                   headers=auth_header
               )
           )
       ],
   )
       

5. Run your agent with ADK Web. From your project directory, execute:

   adk web --port 5000 .

   Note: If you installed ADK with pip install --user, the adk command may not be in your PATH. You can either:

   • Use the full path: ~/Library/Python/3.x/bin/adk (on macOS)
   • Add to PATH: export PATH="$HOME/Library/Python/3.x/bin:$PATH"
   • Use a virtual environment where the PATH is automatically configured
6. Open the ADK Web interface in your browser (typically http://localhost:5000).
7. Select your agent from the dropdown menu (it will be named based on the name parameter in your agent configuration).
8. Start interacting with your CSV data through natural language queries. Your agent now has access to your CSV data through the CData Connect AI MCP Server.

Step 3: Build Intelligent Agents with Live CSV Data Access

With your Google ADK agent configured and connected to CData Connect AI, you can now build sophisticated agents that interact with your CSV data using natural language. The MCP integration provides your agents with powerful data access capabilities.

Available MCP Tools for Your Agent

Your Google ADK agent has access to the following CData Connect AI MCP tools:

• queryData: Execute SQL queries against connected data sources and retrieve results
• getCatalogs: Retrieve a list of available connections from CData Connect AI
• getSchemas: Retrieve database schemas for a specific catalog
• getTables: Retrieve database tables for a specific catalog and schema
• getColumns: Retrieve column metadata for a specific table
• getProcedures: Retrieve stored procedures for a specific catalog and schema
• getProcedureParameters: Retrieve parameter metadata for stored procedures
• executeProcedure: Execute stored procedures with parameters

Example Use Cases

Here are some examples of what your Google ADK agents can do with live CSV data access:

• Data Analysis Agent: Build an agent that analyzes trends, patterns, and anomalies in your CSV data
• Report Generation Agent: Create agents that generate custom reports based on natural language requests
• Data Quality Agent: Develop agents that monitor and validate data quality in real-time
• Business Intelligence Agent: Build agents that answer complex business questions by querying multiple data sources
• Automated Workflow Agent: Create agents that trigger actions based on data conditions in CSV

Testing Your Agent

Once deployed to ADK Web, you can interact with your agent through natural language queries. For example:

• "Show me all customers from the last 30 days"
• "What are the top performing products this quarter?"
• "Analyze sales trends and identify anomalies"
• "Generate a summary report of active projects"
• "Find all records that match specific criteria"

Your Google ADK agent will automatically translate these natural language queries into appropriate SQL queries and execute them against your CSV data through the CData Connect AI MCP Server, providing real-time insights without requiring users to write complex SQL or understand the underlying data structure.
