Elasticsearch
A Model Context Protocol server for Elasticsearch clusters. Enables LLMs to manage indices and execute queries.
IMPORTANT NOTE : this was built mainly by feeding examples to claude from the postgres mcp server.
Components
Tools
-
search
- Execute search queries against indices
- Input:
index(string): Target index namequery(object): Elasticsearch query DSL
- Returns search hits
-
create_index
- Create new Elasticsearch indices
- Input:
index(string): Index namemappings(object, optional): Index mappings configurationsettings(object, optional): Index settings configuration
-
list_indices
- List all available indices
- No input required
- Returns array of index information
-
index_document
- Index a document
- Input:
index(string): Target index nameid(string, optional): Document IDdocument(object): Document content
- Returns indexing operation result
Resources
The server provides mapping information for each index:
- Index Mappings (
elasticsearch://<host>/<index>/schema)- JSON mapping information
- Field names, types and configurations
- Automatically discovered from metadata
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.
