mcp-server-elasticsearch

Overview

The Elasticsearch MCP Server connects AI agents to Elasticsearch data using the Model Context Protocol. It enables natural language interactions with Elasticsearch indices, allowing agents to query, analyze, and retrieve data without custom APIs. The server provides tools like list_indices, get_mappings, search, esql, and get_shards to interact with Elasticsearch data through natural language conversations.
