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"
      }
    }
  }
}

• 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”
