The Model Context Protocol (MCP) Server implementation for HANA CLI.

## Overview

The MCP Server exposes HANA CLI functionality to AI coding assistants like Claude, enabling:

- AI-assisted database queries
- Automated schema analysis
- Intelligent data recommendations
- Code generation for data operations

## Repository Files

Complete technical documentation is available in the project:

- **Main Overview:** [MCP Server Development Index](./index.md)
