Elasticsearch MCP server

This is a small helper that connects your AI assistant to Elasticsearch or OpenSearch, the tools many companies use to store and search large amounts of data. Once it is set up, you can just ask questions in plain English instead of writing search queries yourself. It is handy for anyone who works with logs, records, or search data but does not want to learn the query language.

What this MCP server does

You ask your AI a question, like how many records match something or what is in a certain index. The AI sends that request to this helper program running on your computer. The helper then talks to your Elasticsearch or OpenSearch cluster using your login details. It brings the answer back and the AI explains it to you in the chat. If you ask it to change something, like adding or deleting a record, the helper does that too.

What you can do with it

• Search your documents and get matching results
• List all the indices in your cluster
• Check the health and statistics of your cluster
• Look up a single document by its ID
• Create or update a document
• Delete a document or a set of documents
• Test how text gets broken up by an analyzer

Try asking your AI

• “How many documents are in the logs index?”
• “Show me the health of my cluster”
• “Find the last 10 error messages in the logs index”
• “List all the indices and tell me which ones are biggest”

What it gives back to you

You get answers in plain language in your chat window. That could be a count, a list of documents, a summary of your cluster health, or a confirmation that a change was made. For searches, the AI usually shows the matching records or a short summary of them. You do not have to read raw technical output unless you want to.
