opensearch-mcp-server

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.

• 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.

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

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

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"
