• list_indices: List all indices.
• get_index: Returns information (mappings, settings, aliases) about one or more indices.
• create_index: Create a new index.
• delete_index: Delete an index.

Document Operations

• search_documents: Search for documents.
• index_document: Creates or updates a document in the index.
• get_document: Get a document by ID.
• delete_document: Delete a document by ID.
• delete_by_query: Deletes documents matching the provided query.

Cluster Operations

• get_cluster_health: Returns basic information about the health of the cluster.
• get_cluster_stats: Returns high-level overview of cluster statistics.

Alias Operations

• list_aliases: List all aliases.
• get_alias: Get alias information for a specific index.
• put_alias: Create or update an alias for a specific index.
• delete_alias: Delete an alias for a specific index.

Configure Environment Variables

Copy the .env.example file to .env and update the values accordingly.

Start Elasticsearch/OpenSearch Cluster

Start the Elasticsearch/OpenSearch cluster using Docker Compose:

# For Elasticsearch
docker-compose -f docker-compose-elasticsearch.yml up -d

# For OpenSearch
docker-compose -f docker-compose-opensearch.yml up -d

The default Elasticsearch username is elastic and password is test123. The default OpenSearch username is admin and password is admin.

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

Stdio

Option 1: Using uvx

Using uvx will automatically install the package from PyPI, no need to clone the repository locally. Add the following configuration to 's config file claude_desktop_config.json.

// For Elasticsearch
{
  "mcpServers": {
    "elasticsearch-mcp-server": {
      "command": "uvx",
      "args": [
        "elasticsearch-mcp-server"
      ],
      "env": {
        "ELASTICSEARCH_HOSTS": "https://localhost:9200",
        "ELASTICSEARCH_USERNAME": "elastic",
        "ELASTICSEARCH_PASSWORD": "test123"
      }
    }
  }
}

// For OpenSearch
{
  "mcpServers": {
    "opensearch-mcp-server": {
      "command": "uvx",
      "args": [
        "opensearch-mcp-server"
      ],
      "env": {
        "OPENSEARCH_HOSTS": "https://localhost:9200",
        "OPENSEARCH_USERNAME": "admin",
        "OPENSEARCH_PASSWORD": "admin"
      }
    }
  }
}

Option 2: 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.

// For Elasticsearch
{
  "mcpServers": {
    "elasticsearch-mcp-server": {
      "command": "uv",
      "args": [
        "--directory",
        "path/to/src/elasticsearch_mcp_server",
        "run",
        "elasticsearch-mcp-server"
      ],
      "env": {
        "ELASTICSEARCH_HOSTS": "https://localhost:9200",
        "ELASTICSEARCH_USERNAME": "elastic",
        "ELASTICSEARCH_PASSWORD": "test123"
      }
    }
  }
}

// For OpenSearch
{
  "mcpServers": {
    "opensearch-mcp-server": {
      "command": "uv",
      "args": [
        "--directory",
        "path/to/src/elasticsearch_mcp_server",
        "run",
        "opensearch-mcp-server"
      ],
      "env": {
        "OPENSEARCH_HOSTS": "https://localhost:9200",
        "OPENSEARCH_USERNAME": "admin",
        "OPENSEARCH_PASSWORD": "admin"
      }
    }
  }
}

SSE

Option 1: Using uvx

# export environment variables
export ELASTICSEARCH_HOSTS="https://localhost:9200"
export ELASTICSEARCH_USERNAME="elastic"
export ELASTICSEARCH_PASSWORD="test123"

# By default, the SSE MCP server will serve on http://127.0.0.1:8000/sse
uvx elasticsearch-mcp-server --transport sse

# The host, port, and path can be specified using the --host, --port, and --path options
uvx elasticsearch-mcp-server --transport sse --host 0.0.0.0 --port 8000 --path /sse

Option 2: Using uv

# By default, the SSE MCP server will serve on http://127.0.0.1:8000/sse
uv run src/server.py elasticsearch-mcp-server --transport sse

# The host, port, and path can be specified using the --host, --port, and --path options
uv run src/server.py elasticsearch-mcp-server --transport sse --host 0.0.0.0 --port 8000 --path /sse

Streamable HTTP

Option 1: Using uvx

# export environment variables
export ELASTICSEARCH_HOSTS="https://localhost:9200"
export ELASTICSEARCH_USERNAME="elastic"
export ELASTICSEARCH_PASSWORD="test123"

# By default, the Streamable HTTP MCP server will serve on http://127.0.0.1:8000/mcp
uvx elasticsearch-mcp-server --transport streamable-http

# The host, port, and path can be specified using the --host, --port, and --path options
uvx elasticsearch-mcp-server --transport streamable-http --host 0.0.0.0 --port 8000 --path /mcp

Option 2: Using uv

# By default, the Streamable HTTP MCP server will serve on http://127.0.0.1:8000/mcp
uv run src/server.py elasticsearch-mcp-server --transport streamable-http

# The host, port, and path can be specified using the --host, --port, and --path options
uv run src/server.py elasticsearch-mcp-server --transport streamable-http --host 0.0.0.0 --port 8000 --path /mcp
