injectRequestClose

injectRequestClose(): RequestCloseFn

type RequestCloseFn = () => Promise<void>;

import { injectRequestClose } from "ng-mcp-ui/web";

export class PollWidget {
  private readonly requestClose = injectRequestClose();

  async done() {
    await this.requestClose();
  }
}

The call tears down the whole view. It is not the same as a close of a modal.

You want	Use
Remove the view	injectRequestClose
Close a modal and keep the view	MCP_MODAL close()
Make the view smaller	injectDisplayMode with "inline"

Write your state first

The view can go away as soon as the promise resolves. If you use injectViewStore, its host writes are debounced, therefore a pending write can be lost.

Call flush() first.

this.store.flush();
await this.requestClose();

Host support

Supported on the two host runtimes, through different host calls.

Host	Call
Apps SDK	The close request of the host.
MCP Apps	The teardown request of the host.
