HANA MCP Server

Model Context Protocol (MCP) server for seamless SAP HANA database integration with AI agents and development tools.

🚀 Quick Start

1. Install

npm install -g hana-mcp-server

2. Configure Claude Desktop

Update your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\claude\claude_desktop_config.json
Linux: ~/.config/claude/claude_desktop_config.json

{
  "mcpServers": {
    "HANA Database": {
      "command": "hana-mcp-server",
      "env": {
        "HANA_HOST": "your-hana-host.com",
        "HANA_PORT": "443",
        "HANA_USER": "your-username",
        "HANA_PASSWORD": "your-password",
        "HANA_SCHEMA": "your-schema",
        "HANA_SSL": "true",
        "HANA_ENCRYPT": "true",
        "HANA_VALIDATE_CERT": "true",
        "HANA_CONNECTION_TYPE": "auto",
        "HANA_INSTANCE_NUMBER": "10",
        "HANA_DATABASE_NAME": "HQQ",
        "LOG_LEVEL": "info",
        "ENABLE_FILE_LOGGING": "true",
        "ENABLE_CONSOLE_LOGGING": "false"
      }
    }
  }
}

3. Restart Claude Desktop

Close and reopen Claude Desktop to load the configuration.

4. Test It!

Ask Claude: "Show me the available schemas in my HANA database"

🎯 What You Get

Database Operations

• Schema Exploration: List schemas, tables, and table structures
• Query Execution: Run SQL queries with natural language
• Data Sampling: Get sample data from tables
• System Information: Monitor database status and performance

AI Integration

• Natural Language Queries: "Show me all tables in the SYSTEM schema"
• Query Building: "Create a query to find customers with orders > $1000"
• Data Analysis: "Get sample data from the ORDERS table"
• Schema Navigation: "Describe the structure of table CUSTOMERS"

🖥️ Visual Configuration (Recommended)

For easier setup and management, use the HANA MCP UI:

npx hana-mcp-ui

This opens a web interface where you can:

• Configure multiple database environments
• Deploy configurations to Claude Desktop with one click
• Manage active connections
• Test database connectivity

Required Parameters

Optional Parameters

Database Connection Types

1. Single-Container Database

Standard HANA database with single tenant.

Required: HANA_HOST, HANA_USER, HANA_PASSWORD
Optional: HANA_PORT, HANA_SCHEMA

{
  "HANA_HOST": "hana.company.com",
  "HANA_PORT": "443",
  "HANA_USER": "DBADMIN",
  "HANA_PASSWORD": "password",
  "HANA_SCHEMA": "SYSTEM",
  "HANA_CONNECTION_TYPE": "single_container"
}

2. MDC System Database

Multi-tenant system database (manages tenants).

Required: HANA_HOST, HANA_PORT, HANA_INSTANCE_NUMBER, HANA_USER, HANA_PASSWORD
Optional: HANA_SCHEMA

{
  "HANA_HOST": "192.168.1.100",
  "HANA_PORT": "31013",
  "HANA_INSTANCE_NUMBER": "10",
  "HANA_USER": "SYSTEM",
  "HANA_PASSWORD": "password",
  "HANA_SCHEMA": "SYSTEM",
  "HANA_CONNECTION_TYPE": "mdc_system"
}

3. MDC Tenant Database

Multi-tenant tenant database (specific tenant).

Required: HANA_HOST, HANA_PORT, HANA_INSTANCE_NUMBER, HANA_DATABASE_NAME, HANA_USER, HANA_PASSWORD
Optional: HANA_SCHEMA

{
  "HANA_HOST": "192.168.1.100",
  "HANA_PORT": "31013",
  "HANA_INSTANCE_NUMBER": "10",
  "HANA_DATABASE_NAME": "HQQ",
  "HANA_USER": "DBADMIN",
  "HANA_PASSWORD": "password",
  "HANA_SCHEMA": "SYSTEM",
  "HANA_CONNECTION_TYPE": "mdc_tenant"
}

Auto-Detection

When HANA_CONNECTION_TYPE is set to auto (default), the server automatically detects the type:

• If HANA_INSTANCE_NUMBER + HANA_DATABASE_NAME → MDC Tenant
• If only HANA_INSTANCE_NUMBER → MDC System
• If neither → Single-Container
