Features

Index Operations

- list_indices: List all indices in the Elasticsearch 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 Elasticsearch Query DSL.

Cluster Operations

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

Start Elasticsearch Cluster

Start the Elasticsearch cluster using Docker Compose:

docker-compose up -d

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

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

Usage with Claude Desktop

1. Add the following configuration to Claude Desktop's config file claude_desktop_config.json:

{
  "mcpServers": {
    "elasticsearch": {
      "command": "uv",
      "args": [
        "--directory",
        "path/to/elasticsearch_mcp_server/src",
        "run",
        "server.py"
      ],
      "env": {
        "ELASTIC_HOST": "<your_elastic_url>",
        "ELASTIC_USERNAME": "<your_elastic_username>",
        "ELASTIC_PASSWORD": "<your_elastic_password>>"
      }
    }
  }
}

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

3. Restart Claude Desktop to load the new MCP server.

Now you can interact with your Elasticsearch 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"
