Everything in ABAP / Standard ABAP

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.

No published releases; repository quiet for 49 months.

Stateful apps cannot be operated: a stateful session lives in one HTTP request and an MCP call is one request, so `app_start` refuses them. The repository carries no release yet and states the addon has not been run in production use, the 7.02 downport is lint-only with no 7.02 system having run it, and the ABAP Cloud HTTP service setup is written down but still to verify on your own system.

Server side only, and deliberately: the author states there is no realistic way to support the SSE streaming a client needs, so there are no notifications, no `listChanged`, no `subscribe` and no logging. It is also frozen — protocol versions up to 2025-11-25 and no further, with everything after that in a separate V2 SDK, so starting here today is starting on a closed branch.

Stateless by design: with no `Mcp-Session-Id` and no SSE, notifications of any kind, `resources/subscribe` and stream-close cancellation are excluded, which the author states are protocol-level impossibilities on stateless ICF rather than gaps to be filled later within this design. ABAP Cloud is not supported and not planned, the stated reason being SAP pushing its own MCP strategy and features in BTP; the first iteration targets 7.5x classic, with 7.02 to 7.4x served from a separate generated downport repository. No authorization object and no default auth check are delivered, so a user who may call the ICF node may call every `AREA`/`SERVER` registered under it until `check_authorization` is redefined.

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.

Not on the [SAP BTP ABAP environment](artifact:btp-abap-environment) or another cloud ABAP system: the maintainer states the tool is not cloud ready, because the data sources and system tables it reads CDS metadata from are not released for cloud development. It is designed for SAP S/4HANA on-premise or private cloud, and the shipped Fiori application is configured for A4H and developer systems.

Not an end-user app: it reads from any table the user names and writes into tables of the Z/Y namespace, with no authorisation check of its own, so the README asks a project to add its own checks on `S_TABU_DIS`/`S_TABU_NAM` and to restrict who may run it before it is used beyond a development system. XLSX upload and download are not ready for ABAP Cloud yet, and of the upload apps only the JSON one writes the file's rows back to the database.

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.

The app writes to whatever table is passed in the URL parameter `table` and carries no authorisation check of its own, so past a development system it needs authorisation checks added and a restriction on who may run it.

Quiet No published releases; repository quiet for 75 months.

Functional boundary The maintainer calls the project beta, states there are no experiences with productive usage, and leaves productive use at your own risk. Two further conditions are stated: the implementation used a NetWeaver ABAP stack 7.50 and a 7.40 was not tested, and a system user has to be maintained for the websocket services, because the external websocket tools do not support user-based authorization.

For an app that calls `client->set_session_stateful( )`, which needs the ICF session of the system it runs on; apps keeping their state in the draft table, the abap2UI5 default, work unchanged. For an app that reads a request header through the user exit on the source system, because the consumer forwards method, body, path, query string and status, not headers.

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.

Not reachable Not reachable since 2026-10-20.

Functional boundary `run_class` executes code in your system — that is the point and it is also the risk.

Classic BOPF only: business objects of the ABAP Programming Model for SAP Fiori are not handled, and on [the BTP ABAP environment](artifact:btp-abap-environment) or S/4HANA Public Cloud classic BOPF enhancements do not exist. It is version 0.1.0, verified on S/4HANA 2025 (SAP_BASIS 816) on-premise only, and [arc-1](artifact:arc-mcp-arc-1) still marks the plugin API it is built on as experimental. ARC-1 loads no extensions on its multi-target routes and offers none of these tools in its `hyperfocused` tool mode.

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.

Not for S/4HANA Public Cloud or [the BTP ABAP environment](artifact:btp-abap-environment), where the README states there is no `SUBMIT`, NAST or SOAP-RFC; the floor elsewhere is SAP_BASIS 7.50, the `/sap/bc/soap/rfc` service active, and an SAP user with `S_RFC` on the kit's function group as well as the authorizations for the reports and the spool. Print output is NAST messages only, so S/4 Output Management through BRF+ or APOC is outside it, and editing covers SmartForms alone, with Adobe Forms and SAPscript previewable but not editable. A report that opens a popup, calls a screen or is a dialog transaction cannot be run at all.

A compiled binary rather than an npm package, shipped prebuilt per platform and through pip and uvx. It collects anonymous usage telemetry by default, switched off with `--no-telemetry` or `DATAZOO_DISABLE_TELEMETRY=1`. And the BW reach is what distinguishes it — if the work is plain ABAP, that half is weight you are not using.

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.

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.

Its maker offers it commercially.

Reach is the reason to use it and the reason to be careful: reading cluster tables and spool output goes well past what a development tool is normally pointed at. Decide what an agent may reach before granting it, not after.

Smart Form content cannot be read or written, and HR Forms (`PE51`) are not implemented. Installing it needs SAP GUI or WebGUI once, to register the OData services in `/IWFND/MAINT_SERVICE` and to redefine the write service in `SEGW`, and the extension is built against a locally linked ARC-1.

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.

OData v2 only, and untouched since August 2025 — the same author's [Go port](artifact:oisee-odata-mcp-go) is where v4 support and the tool-explosion work went.

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.

Host-specific: outside Kiro the automatic context activation is the part that does not come with it, and what remains is prose you would have to wire in yourself. Breadth over depth by design — thirty-five skills across six product areas is an orientation layer, not a substitute for the focused sets in each.

The commands it writes stop production systems, delete data and import transports, which is why execution is deliberately somebody else's decision. BTP and cloud operations are explicitly out of scope and planned as a separate plugin.

GPL-3.0, which is a licence to read before vendoring any of it into something you ship. Forty plugins is also a lot of always-available surface — the ledger is there because breadth and verification pull in opposite directions, and it does not resolve that so much as report it.

It is a plugin for one server — its own — so it is a stack rather than a component. And the guard is only as good as the profile labels: a production system registered as `DEV` is a production system with the safety off.

Stateful apps cannot be operated: a stateful session lives in one HTTP request and an MCP call is one request, so `app_start` refuses them. The repository carries no release yet and states the addon has not been run in production use, the 7.02 downport is lint-only with no 7.02 system having run it, and the ABAP Cloud HTTP service setup is written down but still to verify on your own system.

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.

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.

It says so itself, in bold, and the atlas repeats it: not legal advice and not a compliance decision. Only SAP, your contract, or SAP support can answer bindingly, and the skill routes legal, commercial and roadmap questions there rather than guessing at them. Treat the output as evidence gathered, not as a verdict.

It is a plugin for one server — its own — so it is a stack rather than a component. And the guard is only as good as the profile labels: a production system registered as `DEV` is a production system with the safety off.

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.

`APP_TITLE` is not applied by the exit: the `title` field was removed from `z2ui5_if_ui5_exit=>ty_s_http_config` in abap2UI5 1.145.0, so an app that wants it as its browser tab title sets it while it runs. The live theme preview runs the frontend action `THEMING` / `setTheme` and needs UI5 1.118 or later; on an older release a saved theme applies with the next page load. The code is written for ABAP 7.50 and the README states there is no downported 7.02 version, no 702 branch and no workflow that builds one.

It sees [abap2UI5](artifact:abap2ui5-abap2ui5) only: the figures come from the framework's HTTP handler, its monitor hook and its draft table, so nothing outside abap2UI5 appears in them. The usage, error and performance tabs stay empty until the handler line is in place or the user exit sets `check_monitor_active`. Recording which employee used which application, when and how fast, is subject to works council co-determination in Germany (§ 87 (1) no. 6 BetrVG); user tracking is `HASH` by default, `NAME` stores user names, and the request recorder keeps the complete request and response of every roundtrip for two days by default.

Not on ABAP Cloud: the system tables and the classic Workbench APIs the screens use are not released for the ABAP Cloud language version, and there is no 7.02 version below the 7.50 floor either. Not where the full original function is needed, since only the listed transactions exist and about 300 buttons and fields are shown disabled. The authorization checks are rebuilt rather than the originals, which is why the README asks that the screens be tried with a restricted user on a sandbox before the ICF service is opened to more people.

Not as it stands on a system past development: it reads the contents of any table the user names without an authorisation check of its own, so access is bounded only by whatever restrictions exist on the underlying handler or service. The README asks for your own checks first, naming `AUTHORITY-CHECK` on `S_TABU_DIS`/`S_TABU_NAM`, and for a restriction on who may run the app. There is no 7.02 downport either, because the selection-screen dependency has no `702` branch.

It runs whatever SQL a user types without an authorisation check of its own, and the native path additionally uses ADBC, which bypasses ABAP authorisations and client separation; the README asks anyone running it beyond a development system to add authorisation checks and restrict who may start the app. The native console needs Standard ABAP, so on ABAP Cloud only the Open SQL console is available.

Not below SAP_BASIS 7.40 SP08, and not on [SAP S/4HANA Cloud Public Edition](external:sap-s4hana-cloud-public-edition) or [the SAP BTP ABAP environment](artifact:btp-abap-environment), where the classic transport check, the report and job calls and the cluster table `INDX` it rests on do not exist and the maintainer names gCTS as the answer instead. Only on a development system where every developer is trusted: each developer's GitHub token is kept in a cluster table encrypted with a key held in the same table, so anybody who can run ABAP on that system can read both, and the separation between author and reviewer holds only as far as that trust does. Not where the gate has to be unconditional — `#NOREVIEW` in a request's short text skips the check for that request, `ZTR_DISABLED` switches it off for a system, a check that cannot reach GitHub lets the release go on, and nothing checks who writes the marker.

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.

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. It has also not been touched since February 2025, which the maintenance reading states — the three later entries here are where the CI, the Web GUI and the testing framing went.

Functional boundary 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. And a UI test is slower and more brittle than the layer below it: this is for what only the screen can answer.

Functional boundary Not against a system holding local repository changes that have not been pushed: Pull Repos overwrites every repository named in zdevsysinit_params, which is why the maintainer leaves that box unticked and calls it a danger zone.

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.

Stateful apps do not work through it: an app calling `client->set_session_stateful( )` needs the ICF session of the system it runs on, and the consumer opens a new HTTP connection per request without forwarding the `sap-contextid` header that addresses that session. Request headers do not cross either, and a user exit on the source system sees the path of the node `/sap/bc/z2ui5_http_srv` rather than the consumer's. For ABAP Cloud there is only the `cloud` branch, which the README describes as an unmaintained prototype from 2025-11, consumer side only and with no CI.

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.

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.
