  "summary": "Elastic's built-in MCP endpoint in Kibana (Elastic 9.2+ and Serverless) exposing Agent Builder tools, such as ES|QL queries, to external MCP hosts.",
  "description": "Endpoint: `{KIBANA_URL}/api/agent_builder/mcp` (or `/s/{SPACE_NAME}/api/agent_builder/mcp` for a custom space). Authenticate with an API key (Elastic Stack deployments and Serverless) or OAuth 2.1 through an application connection (Serverless only, per-user consent). Exposes built-in and custom Agent Builder tools, including Elastic Workflows; a few built-in tools are not available over MCP. Agent Builder requires the appropriate Elastic Stack subscription or Serverless feature tier. It supersedes the standalone `elastic/mcp-server-elasticsearch`, which is deprecated and only gets critical security updates.",
