Usage with Claude Desktop

Add to the "mcpServers" section of your claude_desktop_config.json:

{
  "mcpServers": {
    "elasticsearch": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-elasticsearch",
        "http://localhost:9200"
      ]
    }
  }
}

Docker one liner to run container :

docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -e "xpack.security.enabled=false" docker.elastic.co/elasticsearch/elasticsearch:8.11.3

Replace the URL with your Elasticsearch endpoint.
