How to Connect to Live Presto Data from Sourcegraph Amp (via CData Connect AI)

Sourcegraph Amp is a modern AI agent environment designed for building intelligent, production-ready assistants capable of stateful reasoning, automatic context management, and native MCP (Model Context Protocol) integration. When combined with CData Connect AI, you can leverage Amp to create agents that interact with your Presto data in real time using natural language or SQL-based queries.

CData Connect AI provides a secure, cloud-to-cloud interface for accessing Presto data. Through the Connect AI Remote MCP Server, Amp connects directly to Presto, enabling live data queries and operations without replication. With optimized pushdown capabilities, CData Connect AI executes SQL operations including filters, aggregations, and joins directly in Presto for fast, real-time performance.

In this article, we demonstrate how to configure the Amp agent to conversationally explore your Presto data using natural language or SQL. With Connect AI, you can easily build agents that have secure, live access to Presto along with hundreds of other enterprise data sources.

Prerequisites

1. An active CData Connect AI
2. The Sourcegraph Amp VS Code extension or Amp CLI installed
3. Node.js v20 or higher installed
4. Access to Presto

Getting Started

---

Step 1: Configure Presto Connectivity for Sourcegraph Amp

Connectivity to Presto from Amp is made possible through CData Connect AI Remote MCP. To interact with Presto data from Amp, 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

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

Step 2: Set Up Amp for CData Connect AI

Copy the MCP Endpoint

Amp communicates with Connect AI through the hosted MCP endpoint:

https://mcp.cloud.cdata.com/mcp

This endpoint provides secure, cloud-to-cloud communication between Amp and your Connect AI workspace.

Generate Base64 Credentials

To authenticate Amp with Connect AI, generate your Base64-encoded credentials. For example, in PowerShell:

{Convert}::ToBase64String{(Text.Encoding)}::ASCII.GetBytes("[email protected]:yourPAT")

Replace [email protected] with your Connect AI email and yourPAT with your Personal Access Token.

Register the MCP Server in Amp

Once you have your Base64 string, register the CData Connect AI MCP server with Amp using the following command:

amp mcp add cdata-connect-ai -- npx -y mcp-remote@latest https://mcp.cloud.cdata.com/mcp --header "Authorization: Basic "

This adds your Connect AI configuration to Amp's settings file, enabling communication with CData Connect AI.

Verify Your Connection and Explore Data

Create a New Thread

Start a new Amp session to begin interacting with your data:

amp thread new



Enter the Interactive Chat

Connect to the new thread using:

amp

.


Verify MCP Servers

Inside the Amp shell, check your registered MCP servers:

list mcp

.


Confirm Your Data Source

Confirm that your connected Presto data appears as a catalog by running

getCatalogs

.

Step 3: Build Intelligent Agents with Live Presto Data Access

With your Amp application configured and connected to CData Connect AI, you can now build sophisticated agents that interact with your Presto data using natural language. The MCP integration provides your agents with powerful data access capabilities.

Available MCP Tools for your Agent

Your Amp application has access to the following CData Connect AI MCP tools:

• getCatalogs: Lists all data source catalogs (e.g., Presto1)
• getSchemas: Returns database schemas within the connected catalog
• getTables: Lists all tables and views available under a given schema
• getColumns: Returns column definitions for a specific table or view
• queryData: Executes SQL queries (SELECT, INSERT, UPDATE, DELETE)
• getProcedures: Lists stored procedures or API endpoints
• getProcedureParameters: Returns metadata for stored procedure parameters
• executeProcedure: Invokes stored procedures (e.g., Presto actions)

Key Features of Amp

Amp provides several production-ready capabilities that make it ideal for building intelligent, data-aware AI agents:

• Automatic Context Management: Amp maintains and recalls conversational context automatically, enabling seamless multi-turn interactions without manual state tracking.
• Stateful Conversations: Preserve context and memory across multiple queries to create natural, human-like conversations.
• Native MCP Integration: Amp natively supports the Model Context Protocol (MCP), allowing secure, real-time access to live data from CData Connect AI and other MCP-compatible servers.
• Tool-Oriented Architecture: Tools are treated as first-class components with managed invocation, input validation, and error handling.
• Efficient Context Handling: Amp optimizes prompts dynamically, ensuring relevant information is preserved even when approaching model token limits.
• Cross-Source Querying: Combine and query multiple connected data sources within a single conversational workflow.
• Fine-Grained Permission Controls: Define and enforce tool access levels to maintain data governance and secure integrations.
• Developer-Friendly CLI and SDK: Manage MCP connections, configure agents, and test workflows easily from the Amp CLI or VS Code extension.

Example Use Cases

Here are some examples of what your Amp agents can do with live data access through CData Connect AI:

• Data Analysis Agent: Identify trends and anomalies in Presto data.
• Report Generation Agent: Generate reports from natural language prompts.
• Interactive Chatbot: Explain insights conversationally using live data.
• Data Quality Agent: Monitor and flag real-time data inconsistencies.
• Automated Workflow Agent: Trigger alerts based on defined data conditions.

Testing Your Agent

Once your agent is running, you can interact with it through natural language queries. For example:

• "Show me all new leads from the past 30 days."
• "What are the top-performing campaigns this quarter?"
• "Analyze revenue growth and highlight anomalies."
• "Generate a summary report of current opportunities."
• "Find all records where status is pending approval."
