Integration Pattern with CData Connect AI

Mistral models integrate with CData Connect AI through the function calling API. This enables models to invoke external tools for live data access across 350+ enterprise sources.

CData Connect AI exposes data sources via managed MCP (Model Context Protocol) connectors. Mistral’s Le Chat supports native MCP connectivity out of the box, enabling direct integration with CData Connect AI’s Remote MCP Server. For other Mistral products—including La Plateforme API and custom agent deployments—programmatic connectivity is available through the official Python and TypeScript SDKs using the function calling framework.

Le Chat Direct Integration (Out-of-the-Box)

Mistral Le Chat provides built-in support for custom MCP connectors. Follow these steps to connect Le Chat to enterprise data sources through CData Connect AI:

1. Log into CData Connect AI, navigate to Sources, and click Add Connection. Select your data source and configure the required authentication properties. Click Save & Test to verify connectivity.
2. Navigate to Settings → Access Tokens in CData Connect AI and click Create PAT. Give the token a descriptive name and copy the generated Personal Access Token (PAT) immediately—it is only visible at creation.
3. Log into Le Chat and navigate to Intelligence → Connectors. Click Add Connector and select Custom MCP Connector.
4. Configure the connector with the following details:
   • Connector Name: A descriptive name (e.g., CData_Connect_AI)
   • Connector Server: https://mcp.cloud.cdata.com/mcp
   • Authentication Method: API Token Authentication
   • Header Name: Authorization
   • Header Type: Basic
   • Header Value: [email protected]:YourPAT (replace with your CData Connect AI email and PAT)
5. Click Connect to establish the connection. Verify the MCP connector appears in the Connections section.
6. Start a new chat in Le Chat and click Enable Tools to activate your MCP connector. Run discovery queries such as Get Catalogs or Get Tables to explore available data sources.

Once configured, you can interact with live enterprise data conversationally—running queries, retrieving records, and automating tasks using natural language.

Tool Invocation Flow

The integration follows a request-response pattern where Mistral models generate function calls that CData Connect AI executes:

1. User Query: Natural language request referencing enterprise data
2. Tool Selection: Mistral evaluates available tools and selects appropriate CData Connect AI functions
3. Function Call Generation: Model outputs structured JSON with function name and parameters
4. Remote Execution: CData Connect AI executes the query against the configured data source
5. Result Processing: Mistral receives tabular/SQL results and synthesizes a natural language response

Programmatic Function Calling Implementation

For La Plateforme API and custom deployments, Mistral’s function calling uses JSON schema definitions to describe available tools. Tools are defined with query parameters, schema specifications, and result formats:

from mistralai import Mistral

client = Mistral(api_key="your-api-key")

tools = [
    {
        "type": "function",
        "function": {
            "name": "query_data",
            "description": "Execute SQL query against enterprise data source via CData Connect AI",
            "parameters": {
                "type": "object",
                "properties": {
                    "query": {
                        "type": "string",
                        "description": "SQL SELECT statement to execute"
                    },
                    "catalog": {
                        "type": "string",
                        "description": "Data source catalog name"
                    }
                },
                "required": ["query", "catalog"]
            }
        }
    }
]

response = client.chat.complete(
    model="mistral-large-latest",
    messages=[
        {"role": "system", "content": "You query enterprise data using CData Connect AI."},
        {"role": "user", "content": "Show me Q4 sales by region from Salesforce"}
    ],
    tools=tools,
    tool_choice="auto"
)

Structured Output Handling

Mistral models demonstrate strong performance with structured data responses. When CData Connect AI returns SQL results or tabular data, Mistral parses column headers, data types, and row values to generate accurate summaries.

The response_format parameter with json_object type ensures consistent structured outputs for downstream processing.

Prompt Engineering for Data Workflows

For optimal performance with CData Connect AI, system prompts should include:

• Available data source catalogs and their schemas
• SQL dialect guidance (CData uses SQL-92 with bracket-quoted identifiers)
• Expected output formats for query results
• Error handling instructions for connection failures or invalid queries

Error Handling Behavior

When CData Connect AI returns errors (connection timeouts, SQL syntax errors, permission denied), Mistral models acknowledge the failure and request clarification. For production deployments, implement retry logic and explicit error schemas in tool definitions.
