Everything in ABAP

In the Eclipse mode the server lives in a developer's IDE, binds to 127.0.0.1 and answers any request carrying an `Origin` header with HTTP 403, so a pipeline or a remote agent has nothing to reach; the standalone mode on the runtime of the ADT for VS Code extension is the documented route with no IDE open. A new connection starts in write mode, so the 11 write tools are live against a connected system until someone presses Toggle Read-Only. The dropins route for the two bundles is documented as untested.

Universal mode trades discoverability for size: one generic tool is harder for a model to pick correctly than a named one, which is why it is not the default. On a small service, standard mode is the better answer.

Read-only does not mean low-stakes: a complete picture of who can do what in an SAP system is exactly what an attacker would want, and the ready-made endpoint is the vendor's rather than yours — the README also documents running the server yourself. The authentication is careful; the question of what leaves your landscape is still yours.

An Eclipse installation older than the 2026-03 release, or a Java below 21, cannot take it: both are listed prerequisites, and 2026-03 is named as the oldest release the current ADT installs on. The tenant, region, client ID and client secret are entered per installation in Eclipse preferences, so each developer configures the Cloud ALM connection in their own IDE.

Driving the GUI reaches whatever a user can reach, which is business data and not a development surface. Decide what an agent may do in a session before granting one, not after. Windows only. The HTTP transport is meant for team use but binds to localhost, and unattended multi-user operation is listed as not yet available — a limitation and also the safer default.
