Use the CData Connect AI Remote MCP Server to enable ElevenLabs agents to securely access live Presto data.

ElevenLabs is a leading AI audio platform that enables developers to build conversational voice agents capable of natural, human-like interactions. The ElevenLabs Conversational AI platform allows you to create voice-powered assistants that can reason through tasks, respond dynamically, and interact with external systems in real time.

By integrating ElevenLabs with CData Connect AI through the MCP (Model Context Protocol), your voice agents gain the ability to query, analyze, and act on live Presto data during conversations. This integration bridges ElevenLabs' conversational AI framework with the governed enterprise connectivity of CData Connect AI, ensuring all data access runs securely against authorized sources without manual data movement.

This article outlines the steps to configure Presto connectivity in Connect AI, generate the required authentication credentials, register the Connect AI MCP Server in ElevenLabs, and verify that your voice agent can successfully interact with live Presto data during conversations.

About Presto Data Integration

Accessing and integrating live data from Trino and Presto SQL engines has never been easier with CData. Customers rely on CData connectivity to:

  • Access data from Trino v345 and above (formerly PrestoSQL) and Presto v0.242 and above (formerly PrestoDB)
  • Read and write access all of the data underlying your Trino or Presto instances
  • Optimized query generation for maximum throughput.

Presto and Trino allow users to access a variety of underlying data sources through a single endpoint. When paired with CData connectivity, users get pure, SQL-92 access to their instances, allowing them to integrate business data with a data warehouse or easily access live data directly from their preferred tools, like Power BI and Tableau.

In many cases, CData's live connectivity surpasses the native import functionality available in tools. One customer was unable to effectively use Power BI due to the size of the datasets needed for reporting. When the company implemented the CData Power BI Connector for Presto they were able to generate reports in real-time using the DirectQuery connection mode.


Getting Started


Step 1: Configure Presto connectivity for ElevenLabs

Connectivity to Presto from ElevenLabs is made possible through CData Connect AI's Remote MCP Server. To interact with Presto data from your voice agents, start by creating and configuring a Presto connection in CData Connect AI.

  1. Log into Connect AI, click Sources, and then click Add Connection
  2. Select Presto from the Add Connection panel
  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.
    • KerberosKeytabFile: The Keytab file containing your pairs of Kerberos principals and encrypted keys.
    • User: The user who is authenticating to Kerberos.
    • Password: The password used to authenticate to Kerberos.
  4. Click Save & Test
  5. Navigate to the Permissions tab and update user-based permissions

Add a Personal Access Token

A Personal Access Token (PAT) is used to authenticate the connection to Connect AI from ElevenLabs. It is best practice to create a separate PAT for each integration to maintain granular access control.

  1. Click the gear icon () at the top right of the Connect AI app to open Settings
  2. On the Settings page, go to the Access Tokens section and click Create PAT
  3. Give the PAT a descriptive name (e.g., "ElevenLabs Voice Agent") and click Create
  4. Copy the token when displayed and store it securely. It will not be shown again

With the Presto connection configured and a PAT generated, ElevenLabs can now connect to Presto data through Connect AI.

Step 2: Add the Connect AI MCP Server in ElevenLabs

ElevenLabs supports connecting to external MCP servers that use SSE (Server-Sent Events) or HTTP streamable transport. The CData Connect AI Remote MCP Server is compatible with this integration.

  1. Log into the ElevenLabs platform and navigate to your agent dashboard
  2. Go to Integrations and click + Add Integration to access the MCP server integrations section
  3. Click on Custom MCP Server to add a new integration
  4. Enter the following configuration:
    • Name: CData Connect AI
    • Description: Access live enterprise data from 350+ sources
    • Server URL: https://mcp.cloud.cdata.com/sse
    • Secret Token: Leave empty (authentication is handled via headers)
    • HTTP Headers: Add a header with key Authorization and value Basic your_email:your_PAT
  5. Replace your_email:your_PAT with your Connect AI login email and the Personal Access Token you created earlier. For example: Basic [email protected]:ABC123...XYZ789
  6. Click Save to test the connection and retrieve available tools from Connect AI
  7. The CData Connect AI MCP server is now available to assign to your voice agents

Step 3: Configure your Voice Agent to use Connect AI

With the MCP server registered, you can now add it to your ElevenLabs voice agents to enable real-time data access during conversations.

  1. Create a new agent or edit an existing agent in the ElevenLabs dashboard
  2. In the agent configuration, navigate to the Tools section
  3. Add the CData Connect AI MCP server you configured in Step 2
  4. Configure the tool approval mode based on your requirements:
    • Always Ask: The agent will request permission before each data query (recommended for sensitive data)
    • Fine-Grained: Set approval requirements per tool/action
    • No Approval: The agent can query data autonomously
  5. Save your agent configuration

Step 4: Interact with live data through your Voice Agent

Your ElevenLabs voice agent can now access and query live Presto data through the CData Connect AI MCP Server during conversations.

  1. Start a conversation with your voice agent
  2. Ask your agent data-related questions such as:
    • "What connections are available?"
    • "Show me the schemas for Presto"
    • "Query recent records from Presto data"
    • "Summarize our latest Data"
  3. The agent will use the Connect AI MCP tools to retrieve live data and respond conversationally

Your ElevenLabs voice agent is now fully configured to access and query live Presto data through the CData Connect AI Remote MCP Server, enabling real-time, data-driven voice interactions for your users.
