mcp4odata
An MCP (Model Context Protocol) server that exposes SAP S/4HANA OData services as tools for LLMs. Deployed on SAP Cloud Foundry (BTP).
Overview
LLM / MCP Client
│ Bearer token (XSUAA)
▼
mcp4odata (CF app)
│ SAP Cloud SDK → BTP Destination Service
▼
SAP S/4HANA (CE_SALESORDER_0001, OData v4)
- Inbound auth: XSUAA Bearer token validation via
@sap/xssec - Outbound connectivity: SAP Cloud SDK
executeHttpRequest()with BTP Destination Service - Two MCP transports: Streamable HTTP (MCP 2025-11-25) and SSE fallback (MCP 2024-11-05)

Local Development
Prerequisites
- Node.js 20+
- SAP BTP subaccount with XSUAA and Destination service instances
Setup
npm install
cp .env.example .env
# Fill in VCAP_SERVICES with your XSUAA and Destination credentials
.env structure (see .env.example for the full template):
VCAP_SERVICES='{ "xsuaa": [...], "destination": [...] }'
S4_DESTINATION_NAME=S4HANA_SALESORDER
PORT=3000
Run
npm run dev # tsx watch mode
npm run build # compile TypeScript → dist/
Test with MCP Inspector
Point the inspector at http://localhost:3000/mcp with a valid XSUAA Bearer token.
BTP Destination Configuration
Create an HTTP destination in the BTP cockpit with:
| Field | Value |
|---|---|
| Name | S4HANA_SALESORDER (or your S4_DESTINATION_NAME) |
| Type | HTTP |
| URL | Your S/4HANA base URL |
| Authentication | OAuth2ClientCredentials |
| Token Service URL | XSUAA token endpoint for S/4HANA |
The SAP Cloud SDK reads the Destination service binding from VCAP_SERVICES, fetches the destination, and injects the Authorization header automatically.
Cloud Foundry Deployment
Prerequisites
brew install cloudfoundry/tap/cf-cli@8
cf login -a https://api.cf.<region>.hana.ondemand.com
cf target -o <org> -s <space>
Create required service instances
cf create-service xsuaa application xsuaa-mcp4odata -c xsuaa-config.json
cf create-service destination lite destination-mcp4odata
Deploy
npm run build
cf push
cf logs mcp4odata --recent
Useful CF commands
cf env mcp4odata # inspect bound service credentials
cf set-env mcp4odata S4_DESTINATION_NAME # override env variable
cf restage mcp4odata # restage after env changes
