The official OpenSearch client for Node.js
Opensearch MCP server exists for a simple reason — assistants are far more useful when they can act on Opensearch directly instead of describing what you should do. The official OpenSearch client for Node.js.
The OpenSearch JavaScript client provides a safer and easier way to interact with your OpenSearch cluster. Rather than using OpenSearch from the browser and potentially exposing your data to the public, you can build an OpenSearch client that takes care of sending requests to your cluster.
The server ships on npm as @opensearch-project/opensearch, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Once Opensearch is connected, these are the calls the assistant has available:
Setup — If you prefer to add the client manually or just want to examine the source code, see [opensearch-js](https://github.com/opensearch-project/opensearchThis sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Opensearch's toolset — Setup — is a fair guide to whether it matches your workflow. It is maintained by GitHub Actions; worth a glance at recent repository activity before you build anything load-bearing on it.
