Elastic Agent Builder
Elastic Cloud Serverless projects are autoscaled environments, fully managed by Elastic and available on Elastic Cloud. Availability This functionality is generally available and ready for production usage. Serverless interfaces and procedures might differ from classic Elastic Stack deployments. The Elastic Stack includes Elastic's core products such as Elasticsearch, Kibana, Logstash, and Beats. Availability This functionality is generally available and ready for production usage. This functionality is in technical preview and is ready for evaluation. Use with caution in production; it is not recommended for mission-critical workloads. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features. Specific Support terms apply. Unless stated otherwise on the page, this functionality is available when your Elastic Stack is deployed on Elastic Cloud Hosted, Elastic Cloud Enterprise, Elastic Cloud on Kubernetes, and self-managed environments. This documentation corresponds to the latest patch available for each minor version. If you're not using the latest patch, check the release notes for changes.

Elastic Agent Builder is an AI conversational platform that lets you create AI agents that answer questions and take actions over your Elasticsearch data using natural language. Agents combine LLM reasoning and context engineering with built-in and custom tools that query your indices, so responses are grounded in your data. Key use cases include:
- Chat with your Elasticsearch data immediately using the chat interface, preconfigured agents, and built-in tools available out of the box.
- Build custom agents and tools tailored to your specific use cases using the UI or APIs.
- Import tools from external MCP servers to give your agents additional capabilities.
- Expose tools and agents to external systems like Claude Desktop, Cursor, and LangChain apps through the MCP server, A2A server, and REST APIs.

To get started you need an Elastic deployment and you might need to enable the feature.
Get started with Elastic Agent Builder
This feature requires the appropriate Elastic Stack subscription or Serverless project feature tier.
- Elasticsearch relevance and security: Leverage Elasticsearch's search capabilities for precise context retrieval, with secure data access controls.
- Built-in agents and tools: Get started immediately with pre-configured agents and tools available out of the box.
- Chat UI: Chat with agents in real time using natural language.
- Custom and external tools: Build targeted custom tools to deliver precise context, or import external tools through the Model Context Protocol.
- Skills: Extend agents with domain-specific expertise using built-in skills or custom skills that bundle knowledge and tools for specific task domains.
- Custom agents: Create agents with tailored instructions and toolsets for specific use cases.
- MCP and A2A servers: Expose tools and agents to external clients through the MCP server and A2A server.
- Kibana REST APIs: Work with Agent Builder functionalities programmatically, including agents, tools, and conversations.
- Elastic Workflows integration: Automate complex processes within your deployment using the Elastic-native automation engine. Your agents can trigger workflows and workflows can invoke agents in their steps.
The Elastic Agent Builder framework consists of four key components: Agent Chat, Agents, Skills, and Tools.
Agent Chat is the synchronous chat interface for interacting with agents through natural language. The chat UI enables real-time communication where you can ask questions, request data analysis, and receive immediate responses from your configured agents. You can also chat with agents programmatically.
Agents are powered by custom LLM instructions and the ability to use tools to answer questions, take action, or support workflows. Each agent translates natural language requests into specific actions using the tools assigned to it. Choose from a set of built-in agents, or create your own.
Skills are reusable instruction sets that give agents specialized expertise for particular task domains. A skill bundles knowledge content and tools so the agent knows how to approach a specific type of task. Skills load selectively based on the user's query, keeping agent configurations clean while enabling deep domain expertise. Choose from a set of built-in skills, or create your own.
Tools are modular, reusable functions that agents use to search, retrieve, and manipulate Elasticsearch data. Tools are the primary mechanism for connecting agent capabilities to your data. Choose from a set of built-in tools, or create your own and assign them to your custom agents.
On Elastic Cloud Hosted and Elastic Cloud Serverless, Elastic Agent Builder comes with preconfigured models ready to use. You can also configure other model providers using inference endpoints, including local LLMs deployed on your infrastructure.
