TLDR: Elastic has launched Agent Builder, a new developer tool designed to significantly speed up the creation of custom AI agents. This platform allows organizations to build AI agents that directly leverage their proprietary data within Elasticsearch, streamlining the complex process of ‘context engineering’ to ensure agents access relevant information efficiently.
Elastic (NYSE: ESTC) has announced the release of Agent Builder, a comprehensive new platform aimed at empowering developers to rapidly construct custom AI agents using their organization’s unique data. Unveiled on October 21, 2025, Agent Builder is deeply integrated with Elasticsearch, Elastic’s renowned search platform, and is designed to simplify the often-complex process of ‘context engineering’ – ensuring AI agents retrieve and utilize the most relevant organizational data at the opportune moment.
According to Ken Exner, Chief Product Officer at Elastic, “AI agents don’t just need lots of data, they need the right data and tools, with relevance, guardrails, and observability built in.” He further emphasized that while developers already depend on Elasticsearch for finding answers within their diverse business data, Agent Builder elevates this capability by making Elasticsearch one of the fastest platforms for building precise AI agents where retrieval, governance, and orchestration are all handled natively within a single environment.
The new offering addresses a critical challenge faced by many enterprises: scattered and unstructured data sets that hinder AI agents from delivering accurate and contextually relevant responses. Agent Builder provides a unified suite of features that extends Elasticsearch’s capabilities, streamlining the entire operational lifecycle of agents, including development, configuration, execution, customization, and monitoring.
Key capabilities of Elastic Agent Builder include:
Immediate Conversational Functionality: A built-in, native conversational agent allows users to interact with enterprise data directly within Elasticsearch using natural language, transforming data into an active, conversational partner.
Intelligent Built-In Tools for Relevance: The platform includes powerful search capabilities that automatically select the correct indexes, understand data structures, translate natural language into optimized semantic, hybrid, or structured queries, and return only the most relevant context to Large Language Models (LLMs).
Custom Tool Development: Developers can create bespoke tools using Elasticsearch’s ES|QL query language for precise data control.
Bespoke AI Agent Creation: Users can define an agent’s entire persona with custom system prompts, control its tool access, and configure specific security profiles.
Secure Integration: Agent Builder supports integration with Model Context Protocol (MCP) endpoints and agent-to-agent (A2A) communication, all while maintaining robust governance through Elasticsearch’s execution layer.
