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

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.
Usage with Claude Desktop
Option 1: Installing via Smithery
To install Elasticsearch Server for Claude Desktop automatically via Smithery:
npx -y @smithery/cli install elasticsearch-mcp-server --client claude
Option 2: Using uvx
Using uvx
will automatically install the package from PyPI, no need to clone the repository locally. Add the following configuration to Claude Desktop'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 3: 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"
}
}
}
}
- 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 Elasticsearch/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"
Usage with Anthropic MCP Client
uv run mcp_client/client.py src/server.py
