How to Connect to Live HCL Domino 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 HCL Domino data in real-time through natural language queries. This article outlines the process of connecting to HCL Domino using Connect AI Remote MCP and configuring a Google ADK agent to interact with your HCL Domino data through ADK Web.

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

Step 1: Configure HCL Domino Connectivity for Google ADK

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

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

2. Select "HCL Domino" from the Add Connection panel

3. Enter the necessary authentication properties to connect to HCL Domino.

   Connecting to Domino

   To connect to Domino data, set the following properties:

   • URL: The host name or IP of the server hosting the Domino database. Include the port of the server hosting the Domino database. For example: http://sampleserver:1234/
   • DatabaseScope: The name of a scope in the Domino Web UI. The driver exposes forms and views for the schema governed by the specified scope. In the Domino Admin UI, select the Scopes menu in the sidebar. Set this property to the name of an existing scope.

   Authenticating with Domino

   Domino supports authenticating via login credentials or an Entra ID (formerly Azure AD) OAuth application:

   Login Credentials

   To authenticate with login credentials, set the following properties:

   • AuthScheme: Set this to "OAuthPassword"
   • User: The username of the authenticating Domino user
   • Password: The password associated with the authenticating Domino user

   The driver uses the login credentials to automatically perform an OAuth token exchange.

   EntraID (formerly AzureAD)

   This authentication method uses Entra ID (formerly Azure AD) as an IdP to obtain a JWT token. You need to create a custom OAuth application in Entra ID (formerly Azure AD) and configure it as an IdP. To do so, follow the instructions in the Help documentation. Then set the following properties:

   • AuthScheme: Set this to "EntraID (formerly AzureAD)"
   • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
   • OAuthClientId: The Client ID obtained when setting up the custom OAuth application.
   • OAuthClientSecret: The Client secret obtained when setting up the custom OAuth application.
   • CallbackURL: The redirect URI defined when you registered your app. For example: https://localhost:33333
   • AzureTenant: The Microsoft Online tenant being used to access data. Supply either a value in the form companyname.microsoft.com or the tenant ID.

     The tenant ID is the same as the directory ID shown in the Azure Portal's Entra ID (formerly Azure AD) > Properties page.

   
4. Click Save & Test
5. Navigate to the Permissions tab in the Add HCL Domino 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 HCL Domino 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 HCL Domino data through CData Connect AI.
       
       You can help users explore and query their HCL Domino 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 HCL Domino data through natural language queries. Your agent now has access to your HCL Domino data through the CData Connect AI MCP Server.

Step 3: Build Intelligent Agents with Live HCL Domino Data Access

With your Google ADK agent configured and connected to CData Connect AI, you can now build sophisticated agents that interact with your HCL Domino 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 HCL Domino data access:

• Data Analysis Agent: Build an agent that analyzes trends, patterns, and anomalies in your HCL Domino 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 HCL Domino

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 HCL Domino 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.
