The Model Context Protocol (MCP) server lets external MCP hosts use the tools you have built in Elastic Agent Builder. For example, you can run an ES|QL query against your data from Claude Desktop without opening Kibana.
The server is available at a Kibana endpoint, with an optional space ID in the path for custom spaces. Hosts such as Claude Desktop, Cursor and VS Code connect to that endpoint. The page describes two ways to authenticate. API keys suit automation and shared machine-to-machine use, and work on Elastic Stack deployments and Serverless projects. OAuth 2.1 suits interactive hosts acting for a person, where each user consents separately and acts with their own permissions, and it works only on Serverless projects.
Built-in and custom tools are available through the server, with a few built-in tools excluded because they only return results that the Agent Builder chat can use. When projects are linked through cross-project search, tool calls use the default search scope for the space in the URL.
The audience is developers and teams who already use Elastic data and want to query it or run Agent Builder tools from an MCP host. The page links to setup guides for specific hosts. It states that Agent Builder has a 14-day free trial, but it does not give plan prices for the MCP server.
