“Elastic Agent Builder MCP server”

 Elastic · upstream description ↗ Our analysis follows below.

01 / THE REASONING

## Why this made the selection.

 - Uses the documented successor to the deprecated standalone Elasticsearch MCP server.
- The setup distinguishes a shared API-key identity from per-user OAuth permissions.

### A good fit for

 - Querying an authorized Elastic data space or using its reviewed Agent Builder tools from an external client.

### Weigh up before choosing

 - OAuth is documented for Serverless projects; Elastic Stack deployments use the API-key path.
- A shared API key gives callers one shared identity; the tool catalog can include workflows and should not be assumed read-only.

02 / THE REVIEW RECORD

## What we actually inspected.

Source review has boundaries. A clear record is more useful than a “safe” badge.

### Material inspected

 - https://www.elastic.co/docs/explore-analyze/ai-features/agent-builder/mcp-server (setup, access and capability sections)

### Our findings

 - The endpoint uses /api/agent_builder/mcp, with /s/{SPACE_NAME} for a custom space.
- Cross-project searches use the default search scope of the selected space, so the MCP URL affects data scope.

### Not established by this review

 - Authentication, service availability and tool execution were not tested.
- The hosted implementation source and licence were not established.

The review applies to the material and revision named here. A newer upstream release can change its behavior.

03 / PUT IT TO WORK

## Connect a server deliberately.

Upstream setup instructions ↗
 - Copy the MCP URL from the Agent Builder Tools interface, including the intended Kibana space.
- Configure a limited API key, or register an OAuth application connection on a supported Serverless deployment.

### Before you start

 - An Elastic deployment with Agent Builder and access to the intended tools/data space.

### Compatibility

A client supporting the documented remote transport and authentication flow.

### Transports

HTTP

### Remote service / documented account access

 - Uses the Agent Builder tool catalog under API-key or user permissions, including configured workflows.

### Cost model

Elastic deployment, account and tool/service usage determine cost.
