Everything in the atlas

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.

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.

Not for production: the README states local and development instances only, and the server refuses a HAC URL whose host is not private unless `HAC_ALLOW_REMOTE=true` overrides that guard. Masking applies to `config_get` only, so `logs_tail` and `monitoring_info` output, thread dumps included, is unmasked and may carry sensitive data, and whatever a tool returns goes to the MCP client and its model. Certificate checks are disabled whenever `HAC_INSECURE_TLS=true` is set, which the README names as typical for local HAC.

Not for a project below the 2211-jdk21.1 baseline: older releases and the JSP Accelerator are covered only as explicitly marked legacy material, so a JSP storefront or a pre-JDK-21 platform is outside what the guides are written against. Knowledge with reach only through one script — it can tell an agent what to write and, apart from `query-items.sh`, cannot let it read what a given system contains.

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.

Two skills, narrowly scoped: nothing here scaffolds an application or answers what a component's API is — that is [@ui5/webcomponents-mcp-server](artifact:ui5-webcomponents-mcp-server), which reads the same library's documentation.

Guidance, not access: these are instructions handed to an agent, and what the agent can then read of your project comes from [@ui5/mcp-server](artifact:ui5-mcp-server) or the editor. A modernisation workflow that runs autonomously across a codebase is also a thing to point at a branch rather than at main.

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

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.

A team that does not keep one long-lived branch per environment has no environment branches for it to compare feature branches against. What it reports is the merge state of branches in Git, so it says nothing about whether a merged change has been built or deployed to the environment.

Not in a project whose dependencies must all carry an open-source licence: KAEV is proprietary software, its licence page states that downloading or viewing the npm package does not by itself grant permission to use, copy, modify, redistribute, sublicense, sell, host or create derivative works, and the LICENSE file shipped with the package carries the controlling terms. Not as the last word on whether a UI5 application is secure: its rule reference states that a heuristic finding is not proof of a vulnerability, and its documentation puts professional security review beside it rather than under it.

Lowercase HTML tags such as `<div>` typecheck but throw: the default renderer constructs UI5 controls, and the HTML-aware renderer plugin is described as planned. `withScope` restores the previous scope on a synchronous return only, so an `await` inside its callback leaks the scope on runtimes without `AsyncLocalStorage`. A view that has to stay adaptable through UI5 flexibility has no path here yet: the project's [Devtoberfest session](content:devtoberfest-2026-ui5-views-type-safe-tsx) states that flexibility support is not built in yet.

Where the login cannot be completed by configuration. Its authentication page states that multi-factor authentication is not supported, because a media break between browser and phone cannot be managed out of the box.

The page and the [abap2UI5](artifact:abap2ui5-abap2ui5) service have to share an origin: an `endpoint` that resolves to another origin is refused, and abap2UI5 rejects a POST whose `Origin` names another host. A host that routes by the URL hash, such as a Fiori elements app or an app with a UI5 router, needs abap2UI5 1.146.0 or later, because 1.145.0 clears the host's hash after every roundtrip. One frontend per page: the first control that starts decides which endpoint the frontend comes from.

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

Functional boundary It reports what the change log says, not what your application uses, so it cannot tell you which of the listed changes touches your code. The repository carries no licence file, which leaves the code itself with no grant attached even though the hosted app is open to use.

It shows the wiring and a converted view pair, not the runtime's API surface; the directives, the plugin SPI and the binding forms are demonstrated in [@ui5-community/jsx-runtime-showcase](artifact:ui5-community-jsx-runtime-showcase) instead.

Its views are not a template for application code: every showcase view overrides `getController()` to return itself so a sample stays readable in one file, and the gotchas page says not to ship that in production, where a view keeps a separate `*.controller.ts`. Routing from a sample, an `ODataModel` v2 or v4, `sap.ui.mdc.Table`, forms and custom control authoring in TSX are absent by decision and documented as deferred.
