> Elasticsearch MCP Server with a Semantic-to-Lexical layer for Business rules

Hello guys,

this is A generic [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) server that connects LLMs to Elasticsearch, with a **Semantic-to-Lexical (S2L) layer** that translates technical field names into business knowledge — without hardcoding any domain logic in the server itself.
