Build Agents in Relevance AI with Access to Live Presto Data via CData Connect AI
Relevance AI is an AI automation and agent-building platform that enables organizations to create autonomous workflows powered by natural language reasoning. Users can visually design agents that interact with APIs, databases, and third-party systems to complete everyday business tasks or data operations.
By integrating Relevance AI with CData Connect AI through the built-in MCP (Model Context Protocol) Server, your agents can query, summarize, and act on live Presto data in real time. This connection bridges Relevance AI intelligent workflow engine with the governed enterprise connectivity of CData Connect AI ensuring every query runs securely against authorized sources without manual data export.
This article outlines the steps to configure Presto connectivity in Connect AI, register the CData MCP Server in Relevance AI, and build an agent that interacts with live Presto data.
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 Relevance AI
Connectivity to Presto from Relevance AI is made possible through CData Connect AI's Remote MCP Server. To interact with Presto data from Relevance AI, we start by creating and configuring a Presto connection in CData Connect AI.
- Log into Connect AI, click Sources, and then click Add Connection
- Select Presto from the Add Connection panel
-
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.
- Click Save & Test
- 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 Relevance AI. It is best practice to create a separate PAT for each integration to maintain granular access control.
- Click the gear icon () at the top right of the Connect AI app to open Settings
- On the Settings page, go to the Access Tokens section and click Create PAT
- Give the PAT a descriptive name and click Create
- Copy the token when displayed and store it securely. It will not be shown again
With the Presto connection configured and a PAT generated, Relevance AI can now connect to Presto data through the CData MCP Server.
Step 2: Configure Connectivity in Relevance AI
The CData Connect AI MCP endpoint and authorization details are registered within Relevance AI so that agents can call live data from Connect AI.
- Sign in to Relevance AI and create an account if you do not already have one
- From the sidebar, navigate to Agents and then click on New Agent
- Select Build from scratch and name the agent (eg; CData MCP Server)
- Inside the agent editor, select Advanced and then switch to the MCP Server tab
- Click + Add Remote MCP Tools
- In the dialog that appears, fill out the fields as follows:
- URL: https://mcp.cloud.cdata.com/mcp
- Label: Any custom label (eg; cdata_mcp_server)
- Authentication: Select Custom headers
- Add header key:value pair. Combine your email and PAT as email:PAT and encode that string in Base64 and then prefix with the word Basic
- Key: Authorization
- Value: Basic base64(email:PAT)
Click Connect to establish the connection. Relevance AI will verify your credentials and register the CData Connect AI MCP Server for use in agents.
Step 3: Build and Run a Relevance AI Agent with Live Presto Data
- Switch to the Run tab for your agent
- Enter a task for example, "List the five most recent incidents from ServiceNow"
- The agent will query Connect AI via the MCP endpoint and display live results from Presto data
With the connection complete, Relevance AI agents can now issue queries, retrieve records, and perform AI-driven tasks over live Presto data through CData Connect AI MCP Server.
