## OpenSearch MCP Server
**opensearch-mcp-server-py** is a Model Context Protocol (MCP) server for OpenSearch that enables AI assistants to interact with OpenSearch clusters. It provides a standardized interface for AI models to perform operations like searching indices, retrieving mappings, and managing shards through both stdio and streaming (SSE/Streamable HTTP) protocols.

**Key features:**
- Seamless integration with AI assistants and LLMs through the MCP protocol
- Support for both stdio and streaming server transports (SSE and Streamable HTTP)
- Built-in tools for common OpenSearch operations
- Easy integration with Claude Desktop and LangChain
- Secure authentication using basic auth or IAM roles
