Overview

What is Elasticsearch MCP Server?

A Model Context Protocol (MCP) server implementation that provides Elasticsearch interaction. It enables searching documents, analyzing indices, and managing a cluster through a set of tools, designed for use with MCP clients like Claude Desktop.

How to use Elasticsearch MCP Server?

Configure the server in your MCP client (e.g., Claude Desktop) by setting environment variables ELASTIC_HOST, ELASTIC_USERNAME, and ELASTIC_PASSWORD to point to your Elasticsearch cluster. Use the provided tools via natural language commands, such as "List all indices in the cluster" or "Show me the cluster health status."

Key features of Elasticsearch MCP Server

list_indices: List all indices in the Elasticsearch cluster.
get_mapping: Retrieve mapping configuration for a specific index.
get_settings: Get settings configuration for a specific index.
search_documents: Search documents using Elasticsearch Query DSL.
get_cluster_health: Get health status of the cluster.
get_cluster_stats: Get statistical information about the cluster.

Use cases of Elasticsearch MCP Server

Query and explore indices in your Elasticsearch cluster via natural language.
Monitor cluster health and statistics without manual API calls.
Retrieve index mappings and settings for troubleshooting or documentation.
Search documents using complex Query DSL without writing raw JSON.
