概要

What is OpenSearch MCP Server?

OpenSearch MCP Server is a Model Context Protocol (MCP) server implementation that provides OpenSearch interaction, enabling searching documents, analyzing indices, and managing a cluster through a set of tools. It is a fork of the Elasticsearch MCP Server converted to work with OpenSearch.

How to use OpenSearch MCP Server?

Clone the repository, then configure Claude Desktop’s config file (claude_desktop_config.json) with the uv command pointing to the local source directory. Set environment variables OPENSEARCH_HOST, OPENSEARCH_USERNAME, OPENSEARCH_PASSWORD, and DASHBOARDS_HOST. Restart Claude Desktop to load the server.

FAQ from OpenSearch MCP Server

How does OpenSearch MCP Server authenticate to the OpenSearch cluster?

Authentication is handled via environment variables OPENSEARCH_USERNAME and OPENSEARCH_PASSWORD. The server uses these credentials to connect to the host specified in OPENSEARCH_HOST.

What are the runtime dependencies?

The server requires uv (Python package manager) and the source code cloned from the repository. No additional system-wide installations are described beyond a Python environment.

Can I run the server without a local Docker cluster?

The README shows starting an OpenSearch cluster with Docker Compose, but the server itself only requires a reachable OpenSearch host. You can point it at any existing cluster by configuring the environment variables.

Does the server support OpenSearch Dashboards?

Yes, it includes a DASHBOARDS_HOST environment variable to connect to Dashboards (Kibana equivalent) for UI access.

What transport and security options are available?

The server uses MCP (stdio-based) transport. Security is provided by the username/password authentication sent over HTTPS (the example uses https://localhost:9200).
