Everything in ABAP / Standard ABAP

A descendant rather than a distinct idea: if what you need is the ADT surface itself, its ancestors are entered here too and one of them may already be in your stack.

Commercial Its maker offers it commercially.

Functional boundary The MIT licence covers the connector only: connecting to SAP needs a licensed ABAPilot backend installed in your system, so this is a commercial decision wearing an open-source badge on one half. Its own published checks did not cover writes, activation, transports or authorisation boundaries.

Archived The declared repository is archived.

Functional boundary With one SAP system the README says to point the client at that arc-1 directly. Version 1 exchanges tokens within a single subaccount, so backends spread across subaccounts are out; it keeps its session map in memory, so more than one instance needs sticky sessions or a shared store. It routes deterministically and runs no model, which is a different thing from an assistant that reasons across systems. The `/all` endpoint drops the per-connection isolation, and the maintainer's answer to that is a PROD backend set read-only at the SAP end rather than a tool surface that hides the writes.

It puts create, update and delete on business entities behind natural language. Whatever the destination's principal may change, an agent may change — and "create a new customer" is a sentence, not a form somebody signed off.

Its README says it plainly and so does this entry: this is not a simulation, every tool call reaches a live BW system, and write operations produce real changes. BW modelling objects are the definition of a warehouse — the blast radius of a wrong one is every report built on it.

Two licences, by which package you install: the standalone server, `@mcp-abap-adt/core`, is AGPL-3.0-only, a licence to read before shipping anything built around it; the library, `@mcp-abap-adt/lib`, is Apache-2.0. The destination model also expects service keys sitting in a local directory, which is a secrets decision to make deliberately.

LISA does the translation step only: it does not discover objects or manage transports, and its README pairs it with [an ADT MCP server](artifact:sap-adt-mcp-server) for those. Every write needs a transport request, and which object types it can write differs between public cloud or [the SAP BTP ABAP environment](artifact:btp-abap-environment) and on-premise or private cloud, and by release. Running it locally is meant for development and testing, not production.

Every tool its README lists reads — Get and Search, nothing that writes. Locking, editing, activation and transports are the other server, [mcp-abap-abap-adt-api](artifact:mario-andreschak-mcp-abap-adt-api), and mixing the two is how you end up with two MCP servers pointed at one system.

It reads documentation, never a system: nothing in it opens a package.json, a CDS model or an ABAP client, so a question about what your own project does has to be answered elsewhere. The offline half is only as fresh as the submodules the last build pinned, and the index answers where something is written down rather than which of two packages fits a task.

Not a system to run a business application on: there is no business application in it, and what it implements of the language, the dictionary and Gateway is a stated subset of each. It is a clean-room reimplementation of the `/IWBEP/` interfaces that bundles no SAP source and no standard DDIC, so a service that reads standard objects has nothing to read, and `ANORMALIES.md` records every place the runtime differs from SAP before any workaround is written.

It answers about the object catalogue, not about your code: nothing here reads your system, so it will tell you a table is not released and not that you used it. That check is ATC's, and this is what makes ATC's answer actionable.

It needs an S-user with SAP Support Portal access, so there is nothing to search without a support contract behind the login. The maintainer states it uses private SAP APIs behind authentication, asks the reader to check whether that use breaches SAP's terms of service, and disclaims both liability and any guarantee that it keeps working. MFA is handled only by typing the code into a visible browser, so a headless deployment cannot complete a login that demands one.

No license Neither the package manifest nor the repository tree declares a licence.

Functional boundary The data is illustrative: availability is binary and backup capacity unlimited, and the model carries no inventory; nothing in it is forecast or priced. The recall half runs only against classic ABAP, because its openCypher trace goes through ADBC, which is not released for ABAP Cloud, and it expects an SSH tunnel to the A4H system it was built against. A plain `npm start` passes no model key, so the agent cannot be used on a server started that way.

The Markdown is a snapshot of whatever help.sap.com served when the pipeline last ran, and the Standard library is scraped from the `latest` index, so which release a page describes follows from the scrape date rather than from anything the corpus states. `package.json` states ISC and the repository carries no LICENSE file, so what the copied SAP documentation may be used for is not stated in it.
