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.

Exports AsyncAPI documents for a CAP service's events
Generates Open Resource Discovery documents from a CAP model
Exposes a CAP service as OData V2

CAP Node.js server behind the OData Deep Dive tutorials
Generates OpenAPI documents from a CDS service
Swagger UI for a CAP service's OpenAPI definition
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.

CAP Node.js attachments with database, S3, Azure or GCP storage
CAP attachments stored in an SAP Document Management repository
If document versions are required, [@cap-js/sdm](artifact:cap-js-sdm) excludes versioned repositories in its [documented restrictions](https://raw.githubusercontent.com/cap-js/sdm/ad13b61f21816ebead2d08264a74521cfb75846c/README.md).
CAP Node.js attachments plugin with database or cloud storage
CAP caching plugin for query results and remote service responses
When user-dependent responses are cached without user-aware or explicit operation keys, or translated responses share keys across locales. These cases require key isolation; locale-aware keys are off by default.
Data federation for CAP via delegation, caching and replication
Collaborative draft support for CAP Node.js services
The maintainer marks this under active development; public APIs, annotation names and OData contracts may still change.

CAP-to-CAP data federation over SAP HANA synonyms
When your adoption policy excludes experimental dependencies: the [maintainer’s README](https://github.com/cap-js/cds-federation-synonyms#about-this-project) explicitly labels this plugin experimental.

Transactional processing of asynchronous and periodic CAP events
If you need sub-second fan-out to external consumers this is the wrong layer — reach for [Event Mesh](artifact:btp-event-mesh) or Kafka. Without [Redis](external:redis), periodic processing still works but instant dispatch degrades to polling.

Business notifications from CAP to SAP Build WorkZone
Annotation-driven mail on CAP entity lifecycle events
Node below 22, or [@sap/cds](artifact:sap-cds) below 9: the package declares the first in engines and the second as a peer dependency. Any mail path other than Microsoft Graph, until a provider is written for it: graph is the only kind that sends, and basic, the kind configured by default, is the base class such a provider extends.
Copy of @cap-js/notifications published under another scope
Reach for the original unless you know why you are not. This is a republished copy rather than a fork with a direction of its own: the README points at cap-js/notifications for the details, and nothing here says what was changed or why.

Composite CAP app from separately deployed services
CAP travel-booking app built on xflights master data
CAP service for typed decisions about one text or JSON state
CAP Java is outside it: the plugin is written for CAP Node.js applications, and `cds add decisions` prints a message and writes nothing in a Java project. A decision needs an answer, so the service cannot be queued: a truthy `queued`, `outboxed` or `outbox` setting fails with `INVALID_CONFIG`, which rules out handing a call to the outbox. The package is not yet on npm, so it is installed from a GitHub release archive, and the subclass hooks, the HTTP mock server, the `cds add` facet and the provider test kit are marked experimental.

CAP service kind putting eleven model providers behind one API
Financial Risk Analyzer built by an agent grounded in SAP MCP servers
CDS plugin for building agents inside a CAP service
Not as a gateway or proxy for SAP Application APIs: capire's guide states that CAP-level agents are intended only for exposing custom CAP application services and are not an SAP-endorsed architecture or pathway for agentic access to those APIs, and sends the reader to the SAP Architecture Center for the endorsed routes. Not as the screen a user of the application talks to, either — the chat preview in the generic index.html page is marked experimental and for local development.

No public repository is declared on the package, so the README is the documentation.
UI5 web interface for an agent built in a CAP service
Not where the agent is reached over anything other than A2A: the README states the plugin does not speak anything other than A2A as @cap-js/agents serves it. Not where an upgrade has to be uneventful either — it pins @cap-js/agents to exactly 0.9.1, calls that package pre-1.0 and days old at the time of writing, and says this plugin inherits that instability and to expect breakage on upgrade.

Every CDS service in both samples is marked `@requires: 'any'` and left publicly accessible, which the README says simplifies the testing and deployment process, and it asks for proper authentication mechanisms to be applied in their place.

CDS plugin and UI5 controls for AI text features via SAP AI Core
It is text processing, not an agent: there is no tool calling, no retrieval and no conversation. It needs SAP AI Core, and the backend half needs [@sap-ai-sdk/orchestration](artifact:sap-ai-sdk-orchestration) installed alongside it — an optional peer, so a frontend-only install stays lean.
