From court to code: Build an agentic RAG assistant with Elasticsearch

Oct 17, 2025

Want to see what it really takes to build a smart AI assistant? How about one that can help you make the right fantasy basketball picks?

In this live session, we’ll demonstrate how to instantly activate and ground a high-performance AI agent using the Elastic Agent Builder, and we’ll show how it powers real-world use cases like smarter player picks.

Join JD Armada, developer advocate, for a 20-minute live coding session to learn about:

  • Agent Builder Activation: Enabling the Agent Builder in Elastic's serverless environment with no extra infrastructure setup
  • Data Grounding: Uploading and indexing an NBA dataset directly into Elastic, and automatically defining the data schema
  • ESQL as a Tool: Registering powerful ESQL queries (averages, comparisons) as specialized tools the agent uses for accurate answers
  • External Integration: Exposing the agent via MCP so it can be called and reused by external applications and other LLMs (like Claude Desktop)
  • Insight Generation: Building a custom agent to answer complex, high-value questions like, “Who’s a better pick for my fantasy team, LeBron or Curry?”

Key Highlights:

  • Live demo of an AI assistant that returns real-time, stat-based comparisons
  • See how to expose the agent as an MCP service for seamless external integration across your organization
  • Observing the agent’s reasoning process with built-in tool call traces and structured responses
