Sap S4hana Odata

An MCP (Model Context Protocol) server for querying SAP S/4HANA Business Partner data via OData V2 API. Connects directly to on-premise S/4HANA systems using Basic Authentication.

Tools

Tool	Description
list_business_partners	List business partners with OData filtering, sorting, pagination, and field selection
get_business_partner	Get a specific business partner by ID with optional $expand for addresses, roles, etc.

Setup

npm install
cp .env.example .env   # then edit with your S/4HANA connection details
npm run build

Configuration

All settings are in .env:

Variable	Required	Description	Example
S4HANA_HOSTNAME	Yes	S/4HANA application server hostname	s4hana.example.com
S4HANA_SYSNR	Yes	SAP system number (00-99)	50
S4HANA_USE_HTTPS	No	Use HTTPS (default: true)	true
S4HANA_USERNAME	Yes	SAP technical user	TECH_USER
S4HANA_PASSWORD	Yes	Password	secret123
S4HANA_CLIENT	No	SAP client number	001
S4HANA_ODATA_PATH	No	OData service path (default: /sap/opu/odata/sap/API_BUSINESS_PARTNER)	/sap/opu/odata/sap/API_BUSINESS_PARTNER

Port Calculation

The HTTP/HTTPS port is derived from the system number:

• HTTPS port = 443 + system number (e.g. sysnr 50 -> port 44350)
• HTTP port = 80 + system number (e.g. sysnr 50 -> port 8050)

Finding Your Connection Details

Run transaction SMICM in SAP GUI to find the hostname, system number, and active ports:

1. Open SAP GUI and enter tcode SMICM
2. Go to Goto > Services to see the list of active HTTP/HTTPS services
3. Note the hostname and port numbers — the system number is the last two digits of the port (e.g. port 44350 means sysnr 50)
