OpenSearch MCP Server

Overview

This Repository Fork of elastic-mcp-server and Converted to opensearch-mcp-server MCP Server. It is a Model Context Protocol (MCP) server implementation that provides opensearch interaction. This server enables searching documents, analyzing indices, and managing cluster through a set of tools.

A Model Context Protocol (MCP) server implementation that provides opensearch interaction. This server enables searching documents, analyzing indices, and managing cluster through a set of tools.

Features

Index Operations

list_indices: List all indices in the Opensearch cluster.
get_mapping: Retrieve the mapping configuration for a specific index.
get_settings: Get the settings configuration for a specific index.

Document Operations

search_documents: Search documents in an index using Opensearch Query DSL.

Cluster Operations

get_cluster_health: Get health status of the cluster.
get_cluster_stats: Get statistical information about the cluster.

Start Opensearch Cluster

Start the Opensearch cluster using Docker Compose:

docker-compose up -d

This will start a 3-node Opensearch cluster and Kibana. Default Opensearch username opensearch, password test123.

You can access Kibana from http://localhost:5601.

Usage with Claude Desktop

Using uv with local development

Using uv requires cloning the repository locally and specifying the path to the source code. Add the following configuration to Claude Desktop's config file claude_desktop_config.json.

you need to change path/to/src/opensearch_mcp_server to the path where you cloned the repository.

{
  "mcpServers": {
    "opensearch": {
      "command": "uv",
      "args": [
        "--directory",
        "path/to/src/opensearch_mcp_server",
        "run",
        "opensearch-mcp-server"
      ],
      "env": {
        "OPENSEARCH_HOST": "https://localhost:9200",
        "OPENSEARCH_USERNAME": "opensearch",
        "OPENSEARCH_PASSWORD": "test123",
        "DASHBOARDS_HOST": "https://localhost:5601"
      }
    }
  }
}

On macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
On Windows: %APPDATA%/Claude/claude_desktop_config.json

Restart Claude Desktop to load the new MCP server.

Now you can interact with your Opensearch cluster through Claude using natural language commands like:

"List all indices in the cluster"
"How old is the student Bob?"
"Show me the cluster health status"
