Onesignal user auth MCP integration

No. This toolkit covers users, devices, subscriptions, segments, and outcomes; it exposes no create-notification or send action. Ayro answers in the live channel the customer is already using and updates the OneSignal record so your own campaigns target them correctly.

By alias. View OneSignal User takes an alias label and alias ID, such as an external_id you already set, rather than an email guess. Delete User Alias goes further and requires the user to be identified by one alias while a different alias is the one being removed, which prevents deleting the only identifier on a record.

Update Subscription By Token exists precisely for that case - it enables or disables a subscription using its token when the change is made outside the OneSignal SDK. That means Ayro can honour an opt-out raised over chat, email, or WhatsApp without the customer opening the app.

Yes, one app at a time. Calls are scoped by app_id: View App returns a specific app's settings, View Segments needs the app_id before it will list, and View Broadcasts and View Outcomes are both per app. Ayro targets the app you name rather than merging several workspaces.
