Step 1: Configure CockroachDB Connectivity for OpenAI Applications

Connectivity to CockroachDB from OpenAI applications is made possible through CData Connect AI Remote MCP. To interact with CockroachDB data from your OpenAI assistant, we start by creating and configuring a CockroachDB connection in CData Connect AI.

  1. Log into Connect AI, click Sources, and then click Add Connection
  2. Select "CockroachDB" from the Add Connection panel
  3. Enter the necessary authentication properties to connect to CockroachDB.

    Set the following to connect to CockroachDB.

    • Server: The host name or IP address of the server.
    • Port: The port number of the CockroachDB server. If not specified, the default port is 26257.
    • Database: The name of the Cockroach database. If not specified, you connect to the user's default database.
    • User: The Cockroach DB user account used to authenticate.
    • Password: The password used to authenticate the user.
  4. Click Save & Test
  5. Navigate to the Permissions tab in the Add CockroachDB 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 OpenAI application. 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 CockroachDB data from your OpenAI application.

Step 2: Configure Your OpenAI Python Application for CData Connect AI

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

  1. Ensure you have Python 3.8+ installed and install the required dependencies: 
    pip install openai python-dotenv httpx
  2. Clone or download the OpenAI MCP client from GitHub: 
    git clone https://github.com/CDataSoftware/openai-mcp-client.git
cd openai-mcp-client
  3. Set up your environment variables. Create a .env file in your project root with the following variables: 
    OPENAI_API_KEY=YOUR_OPENAI_API_KEY
MCP_SERVER_URL=https://mcp.cloud.cdata.com/mcp
MCP_USERNAME=YOUR_EMAIL
MCP_PASSWORD=YOUR_PAT
OPENAI_MODEL=gpt-4
    Replace YOUR_OPENAI_API_KEY with your OpenAI API key, YOUR_EMAIL with your Connect AI email address, and YOUR_PAT with the Personal Access Token created in Step 1.
  4. If creating your own application, here's the core implementation for connecting to CData Connect AI MCP Server: 
    import os
import asyncio
import base64
from dotenv import load_dotenv
from mcp_client import MCPServerStreamableHttp, MCPAgent

# Load environment variables
load_dotenv()

async def main():
    """Main chat loop for interacting with CockroachDB data."""
    # Get configuration
    api_key = os.getenv('OPENAI_API_KEY')
    mcp_url = os.getenv('MCP_SERVER_URL', 'https://mcp.cloud.cdata.com/mcp')
    username = os.getenv('MCP_USERNAME', '')
    password = os.getenv('MCP_PASSWORD', '')
    model = os.getenv('OPENAI_MODEL', 'gpt-4')

    # Create auth header for MCP server
    headers = {}
    if username and password:
        auth = base64.b64encode(f"{username}:{password}".encode()).decode()
        headers = {"Authorization": f"Basic {auth}"}

    # Connect to CData MCP Server
    async with MCPServerStreamableHttp(
        name="CData MCP Server",
        params={
            "url": mcp_url,
            "headers": headers,
            "timeout": 30,
            "verify_ssl": True
        }
    ) as mcp_server:

        # Create AI agent with access to CockroachDB data
        agent = MCPAgent(
            name="data_assistant",
            model=model,
            mcp_servers=[mcp_server],
            instructions="""You are a data query assistant with access to CockroachDB data through CData Connect AI.

            Always explain what you're doing and format results clearly.""",
            api_key=api_key
        )

        await agent.initialize()
        print(f"Connected! {len(agent._tools_cache)} tools available.")
        print("
Chat with your CockroachDB data (type 'exit' to quit):
")

        # Interactive chat loop
        conversation = []
        while True:
            user_input = input("You: ")
            if user_input.lower() in ['exit', 'quit']:
                break

            conversation.append({"role": "user", "content": user_input})

            print("Assistant: ", end="", flush=True)
            response = await agent.run(conversation)
            print(response["content"])

            conversation.append({"role": "assistant", "content": response["content"]})

if __name__ == "__main__":
    asyncio.run(main())
  5. Run your OpenAI application: 
    python client.py
