GuniWeb SAP MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 191 installs a week from npm. Last commit 7 Sep 2026.
SAP S/4HANA and ECC: OData V2/V4, IDoc and RFC/BAPI for n8n and other MCP clients
Today is the operative word: we check GuniWeb SAP MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start:
SAP_BASE_URL (Base URL of the SAP system, including any path segment in front of /sap/opu/odata (e.g. https://s4.example.com or https://gateway.example.com/prefix)), SAP_AUTH_TYPE (Authentication type: basic, oauth2, apikey, ias, xsuaa, btp-principal, saml-bearer), SAP_CLIENT (SAP client (Mandant). Appended to every request — a client-dependent Gateway answers 401 without it), SAP_USERNAME (SAP user for basic authentication), SAP_PASSWORD (Password for basic authentication), SAP_MCP_DEMO (Set to true to start a built-in mock S/4HANA instead of connecting to a real system. No SAP_* configuration needed — for trying the server out).
