Everything in the atlas

Only on SAP S/4HANA 2023 and 2025, on premise or private cloud: [SAP S/4HANA Cloud, Public Edition](external:sap-s4hana-cloud-public-edition) and the [SAP BTP ABAP environment](artifact:btp-abap-environment) are listed as coming soon, and a 2023 system has to leave out `ZABAP_PRC_EVENTS_SE_2025`, whose event-based side effects rely on APIs released with S/4HANA 2025. Not for a system that already carries a copy, because object names are global and two versions cannot live side by side, and not for a productive system by way of the `ZABAP_PRC_DEMO*` packages, which the README states are not intended for one and whose init classes delete and rebuild their own tables on every run. While the major version is 0 the public API is not stable: minor bumps carry breaking changes with no deprecation period, so productive use means pinning a tag and reading the CHANGELOG before every upgrade.

There is nothing here for ABAP for Cloud: the requirements name Standard ABAP releases only, and a CDS/SADL based OData service for `ABAP for Cloud` compatibility stands under Limitations & Todo.

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.

On an [SAP BTP ABAP environment](artifact:btp-abap-environment) system only the generated code is left: DDIC creation is not supported on ABAP Cloud, because classic DDIC object creation over REST is not available there. Create DDIC is also disabled where ADT is not installed in the same Eclipse, and Insert into Editor then works with any editor implementing `ITextEditor` instead of the ABAP one.

The project states that until v1.0.0 is reached, breaking changes may occur without prior notice. Rule items do not chain: every rule operates on the original input string, so a format whose second step needs the result of the first needs a custom logic class. A REPLACE rule whose replacement produces the exact same string as the input is reported as `no match`, which the documentation records as a known limitation.

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.

Not where the UI library itself is expected to bind data: the documentation leaves binding a component's content and events to the host framework. Not from a CDN script tag: the project publishes none, so it assumes a build step.

Where the release and programming model offer durable locks, as RAP draft handling does, the README states that those solve the problem at the kernel level and the lock manager is for where that is not an option. A running handler occupies one background work process for as long as any lock is held, and only generated `ENQUEUE_*` modules can be locked.

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.

Neither the package manifest nor the repository tree declares a licence.

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.

Not where SAP's own Google Workspace integration already applies: the README opens by announcing a native integration between Google Workspace and [SAP S/4HANA](external:sap-s4hana), whose first set of features is included in SAP S/4HANA Cloud 2208 and SAP S/4HANA 2022 and needs an additional licence for the SAP Document Management Service. Not where end users cannot each hold a regular Google account, since there is no way to use an enterprise account or to log on to Google Drive through single sign-on, and not where the redirect URL Google calls cannot reach a public top-level domain server. No SAP standard support is provided for it.

DataZoo GmbH calls the extension experimental and states that minimal testing and benchmarking were done. The Business Source License 1.1 it carries restricts offering the software to third parties on a hosted or embedded basis, so an embedding product needs a commercial licence. Telemetry is on by default and is switched off per session with `SET erpl_telemetry_enabled = false` or for the machine with `DATAZOO_DISABLE_TELEMETRY=1`.

Not for a table whose contents matter, and not for one chosen at run time: the name of the table is fixed in the calling code, and the maintainer's own warning is "only hardcode the table name, don't use with important tables, use at own risk!"

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.

Neither the package manifest nor the repository tree declares a licence.

Only on SAP S/4HANA 2023 and 2025, on premise or private cloud: [SAP S/4HANA Cloud, Public Edition](external:sap-s4hana-cloud-public-edition) and the [SAP BTP ABAP environment](artifact:btp-abap-environment) are listed as coming soon, and a 2023 system has to leave out `ZABAP_PRC_EVENTS_SE_2025`, whose event-based side effects rely on APIs released with S/4HANA 2025. Not for a system that already carries a copy, because object names are global and two versions cannot live side by side, and not for a productive system by way of the `ZABAP_PRC_DEMO*` packages, which the README states are not intended for one and whose init classes delete and rebuild their own tables on every run. While the major version is 0 the public API is not stable: minor bumps carry breaking changes with no deprecation period, so productive use means pinning a tag and reading the CHANGELOG before every upgrade.

Input arrives only as JSON, or as plain XML if the ABAP built-in transformation is switched on, whatever the output format is set to. Cross-site calls are limited to JSONP: the maintainer lists CORS support as planned.

DataZoo GmbH calls the extension experimental and states that minimal testing and benchmarking were done. The Business Source License 1.1 it carries restricts offering the software to third parties on a hosted or embedded basis, so an embedding product needs a commercial licence. Telemetry is on by default and is switched off per session with `SET erpl_telemetry_enabled = false` or for the machine with `DATAZOO_DISABLE_TELEMETRY=1`.

BUSL-1.1 rather than node-rfc's Apache-2.0, so a product you distribute has to be read against the licence and its Additional Use Grant first, and the source is closed: the GitHub repository is the issue tracker and the documentation, nothing else. `RfcServerOptions.bgRfcHandlers` raises instead of accepting handlers, so a server receiving inbound bgRFC units is outside what this does. An ABAP `MESSAGE`-raised failure still arrives with its T100 template rather than the rendered sentence, and the dump name is not reported as `key` for that case.

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.

Every gate here runs off-system, so what the class does on a real system and what the view does on the oldest UI5 release it has to serve are what the `pitfalls` catalogues carry and no local run can see. It runs abap2UI5 app classes, so ABAP that is not one has nothing here to deploy into. In system mode the sandbox tools are not offered, and an `app_act` event runs on the system as the configured user.

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.

It reads a UI5 project and the framework's own documentation, not a running system or a backend: a question about the service behind the app is answered somewhere else. Node.js v20.17 or v22.9 and above.

Written for Amazon Q Developer and Kiro, and the central deployment path is ECS Fargate — the further you are from AWS, the more of it is scaffolding you do not need. Python rather than the Node most of this group uses. Its README says the repository is no longer maintained and that the latest version of ABAP Accelerator is shared after registering with AWS for [Modernization Agents for SAP on AWS](https://github.com/aws-for-sap/Modernization-Agents-for-SAP-on-AWS).

A Python 3.10+ CLI, installed with pipx rather than through any SAP-provided package manager. Its own README lists what it does not do yet: where-used, syntax check and unit test runs — for those it says to reach for [ADT/Eclipse](external:eclipse) or an MCP server. First release, v0.1.0, and no standalone LICENSE file in the repository — the MIT grant is in the README and in pyproject.toml's project metadata rather than its own file.

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.

A system that reports itself productive, or whose role the probe cannot prove non-productive, is write-locked with no override, so changing code in production is not something this does. The permission ladder constrains the package, object name and transport request the server itself passes on a write, and is not a sandbox around ABAP it executes: `abap_run`, `abap_test` and the opt-in `core.eval` run under the connected technical user's SAP authorisations, which is where the boundary actually sits. Data preview, dump variable contents and driving a transaction by batch input stay off in every mode, `admin` included, until each is named explicitly.

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.

Single-tenant today, one technical user, with per-user principal propagation on the roadmap — so a shared deployment cannot yet act as the developer who asked. The sibling edition [ARC-1](artifact:arc-mcp-arc-1) speaks ADT directly if you would rather not depend on the language server.

The diff holds only while the object is inactive, since after activation the previous version is gone and a watched journal directory is what the maintainer points to instead. It adds no write path of its own: the IDE writes through SAP's extension, and the README states arc-1 can stay on `SAP_ALLOW_WRITES=false`. DDIC metadata files are skipped, because SAP's own stub for them says they are not supported in ABAP development tools for VS Code.

It lives inside Eclipse and inherits everything that implies — the session is a developer's, not a pipeline's. And it is version-bound: ADT 3.60 or newer for 0.5.1, with 0.3.x the path for ADT 3.58 and 3.59.

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.

Freestyle SQL and `abap_run` mean an agent can read data and execute code, which is well past reading source. Neither is something to grant on a system where the distinction between development tooling and business data matters.

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.

Development and sandbox systems only: the README warns against pointing it at production. Transport release is never executed, since the tool exists to show the policy stopping it, and separation of duties is checked against the `identity.approvers` list in the policy file rather than against SAP authorisations, so it holds as far as that file does and no further. The write path has been tested with ABAP classes and other object types may need adjustments, there is deliberately no tool that creates or deletes an object, and one server instance serves one SAP system.

Its own README opens by calling the server experimental. It also writes: locking, editing and activating in a system an agent can reach is a permissions decision before it is a tooling one.

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.

There is nothing to clone here: "Access is provided through a registration page. Once registered, you will receive access to the GitHub repository containing the agents, deployment guides, and documentation", and that repository answers 404 to anyone who has not registered, so neither the agent code nor the deployment guides can be read before the form is filled in. AWS states the agents are published as an unsupported solution, with customers responsible for testing and securing the code before deploying in production, and that they are intended for non-production SAP environments rather than production systems. The documentation link in the README is still a placeholder.

Real SAP calls need the proprietary [SAP NetWeaver RFC SDK](external:sap-nw-rfc-sdk) and the `pyrfc==3.3.1` release the README calls archived and yanked, on Python 3.11, so without those only the demo backend answers. Not over HTTP as it stands: credentials are read from the environment for stdio, and the README says not to expose the server over HTTP without implementing the MCP authorization specification and deployment-level rate limiting. Multi-tenant auth and RBAC beyond the one server-wide policy, rate limiting, metrics and tracing, and deployment packaging are listed as not built. The result limits protect the client and not the system, since the README states they cannot reduce work already performed inside SAP, and the MCP tool annotations that describe read and write risk are advisory metadata rather than an authorisation boundary, so the service account's `S_RFC` and table authorisations are still what decides.

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.

Read-only in practice, and the documentation is Korean; the tool names are English but the guidance around them is not.

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.

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

Functional boundary It consumes the `@experimental` public API, which the README says may break in any release. The RFC tool dials as one shared technical user with its own credentials, so SAP's log records that user and not the person behind the agent.

Every gate here runs off-system, so what the class does on a real system and what the view does on the oldest UI5 release it has to serve are what the `pitfalls` catalogues carry and no local run can see. It runs abap2UI5 app classes, so ABAP that is not one has nothing here to deploy into. In system mode the sandbox tools are not offered, and an `app_act` event runs on the system as the configured user.

The embedded preview needs a system that accepts basic auth: the documentation states that pure SSO or SAML without a basic-auth fallback is not supported, and points at `external` mode, which opens the app in the normal browser with the existing SAP session. On the web only the language half runs; the preview with its proxy, traffic log and screenshot, Ctrl+F3 activation, the render gate, the workspace-wide check and the MCP servers are desktop-only. The agent app tools send nothing until `abap2ui5.agent.enableAppTools` is switched on in User settings, because an event they fire runs as the configured user and changes data on the system for real.

A system that reports itself productive, or whose role the probe cannot prove non-productive, is write-locked with no override, so changing code in production is not something this does. The permission ladder constrains the package, object name and transport request the server itself passes on a write, and is not a sandbox around ABAP it executes: `abap_run`, `abap_test` and the opt-in `core.eval` run under the connected technical user's SAP authorisations, which is where the boundary actually sits.

On ECC the S/4HANA `API_*` services that the three convenience readers default to do not exist, so each one has to be pointed at a Z service of your own or replaced by the RFC tools. `read_table` inherits `RFC_READ_TABLE`'s 512-byte row, so a wide table needs an explicit field list and some fields cannot be selected at all, and the bridge starts a Node process and a fresh logon per call, with no pooling. The audit log is one line per call that includes the call arguments, so every filter and WHERE clause sent to SAP is written to a file that then has to be handled as sensitive.

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.

Not a substitute for testing in a system: the README states that any class calling the database, classic BAPIs or HTTP is shimmed out and stays an on-stack ATC and ABAP Unit concern, and that an off-stack green is CI-grade provenance rather than an in-system pass. It also assumes a particular shape of project. The ABAP has to be abapGit-serialised into a Git repository, Node.js 22 or later has to be available locally and in CI, and the CI has to be GitHub Actions.

The embedded preview needs a system that accepts basic auth: the documentation states that pure SSO or SAML without a basic-auth fallback is not supported, and points at `external` mode, which opens the app in the normal browser with the existing SAP session. On the web only the language half runs; the preview with its proxy, traffic log and screenshot, Ctrl+F3 activation, the render gate, the workspace-wide check and the MCP servers are desktop-only. The agent app tools send nothing until `abap2ui5.agent.enableAppTools` is switched on in User settings, because an event they fire runs as the configured user and changes data on the system for real.

Every skill that touches ABAP needs [arc-1](artifact:arc-mcp-arc-1) itself connected to a real system; nothing else is universal. `modernize-ui5-app` and `convert-ui5-to-fiori-elements` specifically need [the UI5 MCP server](artifact:ui5-mcp-server) for TypeScript conversion guidance and the linter, `convert-ui5-to-fiori-elements` also needs [the Fiori MCP server](artifact:sap-ux-fiori-mcp-server) for its LROP scaffold, and `modernize-ui5-app` needs a browser MCP (Claude in Chrome or Claude's own Preview) for its final render-verification step, since an HTTP 200 alone does not catch a blank page. A skill file alone, without the servers a given skill needs, has nothing to act on.

Knowledge with no reach: without an MCP server connected it can tell an agent what to write and cannot let it read or run anything. The rules target the ABAP Cloud development model, so a classic on-premise codebase is not what they are written against.

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.

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.

Knowledge about theming, not a theme build: nothing here compiles a theme or deploys one, and it says nothing about a custom control's own parameters.

Neither the package manifest nor the repository tree declares a licence.

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.
