opensearch-project/opensearch-mcp-server-py
opensearch-mcp-server-py is the OpenSearch project's official MCP server for its search and analytics engine. It gives an assistant a standard interface to a cluster: running search queries against indices, listing indices and retrieving their mappings so the model knows the field structure before querying, inspecting cluster and index state, and managing shards. Because mapping retrieval is a first-class tool, the normal pattern is discovery before querying — the model asks what fields exist and of what type, then composes a query that will actually match, rather than guessing at an index it has never seen. Two transports are supported: stdio for a local client such as Claude Desktop, and streaming over SSE or streamable HTTP for a server deployment where several clients or a remote agent connect over the network. The project also documents an agent memory feature, tying conversational state to OpenSearch itself. It is written in Python and lives in the opensearch-project GitHub organisation under the Apache 2.0 licence, which matters for adoption: it is maintained alongside the engine rather than by a third party, so tool coverage tracks OpenSearch releases. The audience is teams running OpenSearch for logs, observability or application search who want analysts to query it in natural language.
