The Elasticsearch/OpenSearch MCP Server enables seamless interaction with Elasticsearch or OpenSearch databases through the Model Context Protocol (MCP). This server provides a comprehensive set of tools for searching documents, managing indices, and administering clusters.

Features

General Operations

  • general_api_request: Perform HTTP API requests for any Elasticsearch/OpenSearch API without a dedicated tool

Index Operations

  • list_indices: List all indices
  • get_index: Retrieve information about indices (mappings, settings, aliases)
  • create_index: Create a new index
  • delete_index: Delete an index
  • create_data_stream: Create a new data stream
  • get_data_stream: Get information about data streams
  • delete_data_stream: Delete data streams and backing indices

Document Operations

  • search_documents: Search for documents
  • index_document: Create or update documents
  • get_document: Retrieve documents by ID
  • delete_document: Delete documents by ID
  • delete_by_query: Delete documents matching a query

Cluster Operations

  • get_cluster_health: Get basic cluster health information
  • get_cluster_stats: Get high-level cluster statistics

Alias Operations

  • list_aliases: List all aliases
  • get_alias: Get alias information for specific indices
  • put_alias: Create or update aliases
  • delete_alias: Delete aliases

Configuration

Configure the MCP server using these environment variables:

Authentication

  • Basic Authentication:
    • ELASTICSEARCH_USERNAME and ELASTICSEARCH_PASSWORD
    • OPENSEARCH_USERNAME and OPENSEARCH_PASSWORD
  • API Key Authentication (Elasticsearch only - recommended):
    • ELASTICSEARCH_API_KEY

Connection Settings

  • ELASTICSEARCH_HOSTS / OPENSEARCH_HOSTS: Comma-separated list of hosts (default: https://localhost:9200)
  • ELASTICSEARCH_VERIFY_CERTS / OPENSEARCH_VERIFY_CERTS: Whether to verify SSL certificates (default: false)

Security Controls

  • DISABLE_HIGH_RISK_OPERATIONS: Set to true to disable all write operations (default: false)
  • DISABLE_OPERATIONS: Comma-separated list of specific operations to disable

When DISABLE_HIGH_RISK_OPERATIONS is enabled, all write operations are hidden, including:

  • Index: create_index, delete_index
  • Document: index_document, delete_document, delete_by_query
  • Data Stream: create_data_stream, delete_data_stream
  • Alias: put_alias, delete_alias
  • General: general_api_request

Example:

# Disable all high-risk operations
export DISABLE_HIGH_RISK_OPERATIONS=true

# Disable specific operations
export DISABLE_OPERATIONS="delete_index,delete_document,delete_by_query"

Getting Started

Start Elasticsearch/OpenSearch Cluster

Launch a local 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

Default credentials:

  • Elasticsearch: username elastic, password test123
  • OpenSearch: username admin, password admin

Access the dashboard at http://localhost:5601.

Running the MCP Server

Using stdio Transport

Option 1: Using uvx (Recommended)

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

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

For API key authentication:

{
  "mcpServers": {
    "elasticsearch-mcp-server": {
      "command": "uvx",
      "args": [
        "elasticsearch-mcp-server"
      ],
      "env": {
        "ELASTICSEARCH_HOSTS": "https://localhost:9200",
        "ELASTICSEARCH_API_KEY": "<YOUR_ELASTICSEARCH_API_KEY>"
      }
    }
  }
}

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 repository

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

Using SSE Transport

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

# Start server (default: http://127.0.0.1:8000/sse)
uvx elasticsearch-mcp-server --transport sse

# Or with custom host, port, path
uvx elasticsearch-mcp-server --transport sse --host 0.0.0.0 --port 8000 --path /sse

Using Streamable HTTP Transport

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

# Start server (default: http://127.0.0.1:8000/mcp)
uvx elasticsearch-mcp-server --transport streamable-http

# Or with custom host, port, path
uvx elasticsearch-mcp-server --transport streamable-http --host 0.0.0.0 --port 8000 --path /mcp

Version Compatibility

The MCP server supports multiple Elasticsearch and OpenSearch versions:

MCP Server Database Compatibility
elasticsearch-mcp-server-es7 Elasticsearch 7.x
elasticsearch-mcp-server Elasticsearch 8.x
elasticsearch-mcp-server-es9 Elasticsearch 9.x
opensearch-mcp-server OpenSearch 1.x, 2.x, 3.x

To use a specific version:

# For Elasticsearch 7.x
uvx elasticsearch-mcp-server-es7

# For Elasticsearch 9.x
uvx elasticsearch-mcp-server-es9

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "elasticsearch-mcp-server" '{"command":"uvx","args":["elasticsearch-mcp-server"],"env":{"ELASTICSEARCH_HOSTS":"https://localhost:9200","ELASTICSEARCH_USERNAME":"elastic","ELASTICSEARCH_PASSWORD":"test123"}}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

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

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json
  • Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

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

3. Restart Claude Desktop for the changes to take effect
