OpenSearch MCP Server

Example Use Cases

• 1

  Inspect OpenSearch index mappings and field types to understand data schemas before querying.

• 2

  Run read-only search queries against specified OpenSearch indices to retrieve relevant documents.

• 3

  Integrate OpenSearch data into LLM workflows and tooling via the Model Context Protocol (e.g., Claude Desktop, Cursor, VS Code Copilot, Windsurf).

Description

This MCP server exposes OpenSearch cluster metadata (index mappings) as resources and provides a read-only search tool for executing queries against specified indices. It is designed to let LLMs and agent frameworks inspect index schemas and retrieve documents without modifying cluster data. The server is intended for easy integration with MCP-aware apps and tools (examples in the README include Claude Desktop, Cursor, GitHub Copilot for VS Code, and Windsurf) and is distributed as an npm package to run via npx.
