Step 1: Configure Presto Connectivity for Mistral

Connectivity to Presto from Mistral AI is made possible through CData Connect AI Remote MCP. To interact with Presto data from Mistral, we start by creating and configuring a Presto connection in CData Connect AI.

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

2. Select "Presto" from the Add Connection panel.
👁 Selecting a data source

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

   Set the Server and Port connection properties to connect, in addition to any authentication properties that may be required.

   To enable TLS/SSL, set UseSSL to true.

   Authenticating with LDAP

   In order to authenticate with LDAP, set the following connection properties:

   • AuthScheme: Set this to LDAP.
   • User: The username being authenticated with in LDAP.
   • Password: The password associated with the User you are authenticating against LDAP with.

   Authenticating with Kerberos

   In order to authenticate with KERBEROS, set the following connection properties:

   • AuthScheme: Set this to KERBEROS.
   • KerberosKDC: The Kerberos Key Distribution Center (KDC) service used to authenticate the user.
   • KerberosRealm: The Kerberos Realm used to authenticate the user with.
   • KerberosSPN: The Service Principal Name for the Kerberos Domain Controller.

   • Password: The password used to authenticate to Kerberos.
   👁 Configuring a connection (Salesforce is shown)
   
4. Click Save & Test.
5. Navigate to the Permissions tab in the Add Presto Connection page and update the user-based permissions. 👁 Updating permissions
   

Add a Personal Access Token

A Personal Access Token (PAT) is used to authenticate the connection to Connect AI from Mistral AI. It is a best practice to create a separate PAT for each service to maintain fine-grained access control.

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 descriptive name and click Create. 👁 Creating a new PAT
   
4. Note: The PAT is only visible at creation, so be sure to copy and store it securely for future use.

With the connection configured and a PAT generated, you are ready to connect to Presto data from Mistral AI workflows.

Step 2: Configure the MCP Connector in Mistral Le Chat

With your Presto connection and PAT created in CData Connect AI, the next step is to configure a custom MCP connector inside Mistral Le Chat.

1. Log into Le Chat. 👁 Logging into Mistral Le Chat
   
2. From the left-hand menu, click on Intelligence, then select Connectors. Click Add Connector. 👁 Adding a new connector
   
3. In the dialog, select Custom MCP Connector and enter the following details:
   • Connector Name: For example, CData_Remote_MCP.
   • Connector Server: https://mcp.cloud.cdata.com/mcp (found in the "Connect Data to AI" ribbon in Connect AI).
   • Authentication Method: API Token Authentication.
   • Header Name: Authorization.
   • Header Value: Basic [email protected]:YourPAT (replace "[email protected]" with your CData Connect AI email and "YourPAT" with the PAT created earlier in above format).
   👁 Configuring the MCP connection
   
4. Click Connect to establish the connection.
5. Scroll down to the bottom of the Connections section to confirm that your MCP connection is successfully established. 👁 MCP connection established
   

This step ensures that Mistral Le Chat can securely route queries through the CData Remote MCP Server to your live Presto data.

Step 3: Query Live Presto Data from Mistral AI

Now that your MCP connector is configured in Le Chat, you can begin querying live Presto data directly in your conversations.

1. In Le Chat, click on Chats in the left menu to start a new chat.
2. Enable your MCP connector by clicking the Enable Tools button. 👁 Enabling MCP tools in Le Chat
   
3. Run a discovery query such as Get Catalogs or Get Tables to see the available data sources and schemas connected through CData Connect AI. 👁 Listing connected catalogs and tables
   
4. Test the connection by running a simple query. For example: "Compare the win rate of Opportunities across different industries." 👁 Viewing visual query results (Salesforce is shown)
   👁 Viewing tabular query results (Salesforce is shown)
   

And that's it! You can now interact with live Presto data conversationally inside Mistral Le Chat.
