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 00:00 Introduction & agenda 00:40 Why build an agentic RAG assistant 02:47 Solving LLM limitations with Elasticsearch & Agent Builder 05:37 Context engineering & relevance 07:00 Setting up Agent Builder & importing data 12:27 Creating custom tools for fantasy basketball 20:53 Building & configuring the NBA Fantasy Assistant Agent 24:29 Compare players in built-in chat 27:07 Integrating with Claude Desktop via MCP 28:08 Recap, Q&A & closing Resources: - Get the dataset for this session: https://github.com/elastic/elastic-coding-sessions/tree/main/02-agentic-rag-assistant - Search Labs Elastic's blog for developers and data scientists: https://www.elastic.co/search-labs/blog/agentic-rag If you’re looking to deploy powerful, data-grounded AI agents fast, this session is for you.
