mcp-server-elasticsearch

Why we included this project

Elasticsearch shops that want their AI agents to talk to the data they already store will get a clear template here. The server exposes Elasticsearch indices to MCP-compatible clients, so an assistant can ask questions in natural language and pull records without you writing bespoke API calls for each case. It runs as a Docker image and supports stdio for local clients plus streamable-HTTP for web integrations, authenticating with an API key or username and password against an 8.x or 9.x cluster. The honest caveat is that Elastic has deprecated this server in favor of its Agent Builder MCP endpoint, so treat it as a working reference for the pattern and a stopgap rather than a long-term dependency. If you are figuring out how to give a chatbot read access to your search index, the setup and protocol choices here show one workable way to do it.
