Elasticsearch

A Model Context Protocol server for Elasticsearch clusters. Enables LLMs to manage indices and execute queries.

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.
