Getting Started

---

Step 1: Configure OData Connectivity for OpenAI Applications

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

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

2. Select "OData" from the Add Connection panel

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

   The User and Password properties, under the Authentication section, must be set to valid OData user credentials. In addition, specify a URL to a valid OData server organization root or OData services file.

   
4. Click Save & Test
5. Navigate to the Permissions tab in the Add OData 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 OData services 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 OData 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 OData data
           agent = MCPAgent(
               name="data_assistant",
               model=model,
               mcp_servers=[mcp_server],
               instructions="""You are a data query assistant with access to OData data through CData Connect AI.
   
               You can help users explore and query their OData services in real-time.

               - Explore table structures
               - Execute SQL queries
               - Provide insights about the data
   
               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 OData services (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
