Comparisons and setup guides on Claude, SAP ECC and S/4HANA and MCP servers, from sandbox deployments and the open-source sap-mcp-server, with sources and dates.

Each piece here answers one question a company on SAP asks before it lets an AI layer near its system: what SAP has actually said, what the open-source server does and does not do, and what a pilot has to settle before production. The claims are tied to sources listed at the end of every page and carry an as-of date, because SAP's conditions move.

Nothing here is a product tour. The comparison names the conditions on both routes, the setup guide is meant to be run against a sandbox, and both say where there is no production reference yet.
