Six CAP features in one package, from replication cache to rate limits
It is a bundle, not a plugin with one job. Depending on it for one feature brings the rest.
Exposes a CAP service as OData V2
WebSocket and Socket.IO adapter for CDS services
Exports AsyncAPI documents for a CAP service's events
GraphQL protocol adapter generated from the CDS model
Exposes CAP services as MCP servers for AI agents
SAP prohibits gateway/proxy use for SAP Application APIs; the Atlas applies that prohibition to CAP wrappers around those APIs. Data changes require application-defined unbound actions, and the adapter supplies no rate limiting, agent-action audit logging, approval workflows or policy enforcement. In beta, with nine releases in the six weeks after the first, so pin it.
Generates OpenAPI documents from a CDS service
Generates Open Resource Discovery documents from a CAP model
Generates an MCP server from annotated CDS entities and actions
MCP server inside a CAP application with model and query tools
CAP plugin letting the REST adapter accept XML payloads
CAP plugin serving the Cardano blockchain as OData V4
MCP server exposing the ODATANO Cardano-to-OData bridge as tools
The repository the package declares has been deleted — verified against the GitHub API, not just a failed fetch. The package is still on npm, so it installs; the source it was published from is no longer readable, which is a harder thing to discover than a stale version number.
CAP plugin indexing the Midnight blockchain, exposed as OData V4
MCP server exposing the NIGHTGATE Midnight attestation layer
Compiler from a CDS service to SEGW model and data provider classes
The generated files are copied or deployed into the ABAP system by hand, the fourth step of its own usage list, so nothing keeps an activated service in step with the model it was generated from. Its peer dependency is `@sap/cds` ^9.8, so it does not install into a project on an earlier CAP release.
CAP Node.js runtime
CDS plugin adding embedded analytics to CAP for SAP Analytics Cloud
Not in a project on CAP 7 or earlier: the package declares `@sap/cds` >=8 and `@sap/cds-compiler` >=5 as peer dependencies.
MCP server answering plain-English questions against a CDS schema
MCP server generated from a CDS model, forked from @gavdi/cap-mcp
Not published to npm. Install from source.
Captures CAP service errors, deduplicates them and mails alerts
Alerting by mail is not telemetry — if you need traces and metrics correlated across handlers, that is a different layer. It also publishes no repository, so the package is the only thing to read.
Swagger UI for a CAP service's OpenAPI definition
MCP adapter turning a CAP Java service into an MCP server
SAP prohibits gateway/proxy use for SAP Application APIs; the Atlas separately excludes CAP wrappers around those APIs from its assessed scope. Data changes require application-defined unbound actions, and the adapter supplies no rate limiting, agent-action audit logging, approval workflows or policy enforcement.
OData V2 protocol adapter built into the CAP Java runtime
OData V4 protocol adapter for CAP Java Application Services
Generates Open Resource Discovery documents from a CAP Java model
Maven bill of materials pinning CAP Java module versions
Eclipse plug-in turning JSON or XML into ABAP types and DDIC objects
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.

ABAP-native MCP endpoint that drives opted-in abap2UI5 apps
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.
MCP server SDK written in ABAP
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 ABAP MCP server SDK for the 2026-07-28 protocol draft
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.
Generates ABAP client classes and server stubs from OpenAPI
Framework for multi-step ABAP processes with monitoring
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.

Functional boundary The maintainer records SSL as a known issue: an SAP Basis problem in older systems that depends on the remote certificate, so a system that cannot carry the remote certificate chain will not complete the call. It is published as free to use at your own risk, with no support statement behind it.

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.
MCP server publishing SAP functions as tools from config tables
Not reachable Not reachable since 2026-10-20.
Functional boundary What it exposes is whatever somebody put in the configuration table, which moves the governance question inside the SAP system and out of the server — an advantage if that table is controlled and a hazard if it is not. The web management interface is a second surface to secure alongside the MCP one.

Local ABAP server serving /IWBEP/ OData v2 without an SAP system
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.

Regex RuleSets that read barcode strings into named fields
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.
