Provides tools for OData interaction with SAP S/4HANA, allowing discovery of services, retrieval of entity metadata and field values, and execution of CRUD queries on SAP entities.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@SAP S/4HANA MCP Server Discover available SAP OData services"
That's it! The server will respond to your query, and you can continue using it as needed.
