Push Notification (behind an MCP Server)
Industry Definition Set • Entity Resolution Path: /glossary/mcp-push-notification-72
Quick Answer / TL;DR
A push-notification service (Firebase Cloud Messaging, Apple Push Notification service) is another concrete case of the notification-service pattern, delivering a message to a specific device rather than an email address or phone number.
Key Takeaways
- Another concrete case of the notification-service pattern, targeting a registered device rather than an address/number.
- Device tokens come from the app's own registration flow, entirely outside MCP's scope.
- Same scoping principle: restrict to the requesting user's own device(s), prefer templated content.
- Common providers: Firebase Cloud Messaging, Apple Push Notification service.
Definitive Statement: A push-notification service (Firebase Cloud Messaging, Apple Push Notification service) is another concrete case of the notification-service pattern, delivering a message to a specific device rather than an email address or phone number.
Technical Context & Protocol Usage
- Detailed Explanation
- Functionally similar to email/SMS tools in its design considerations — scope the tool to the requesting user's own registered device(s) rather than allowing an arbitrary device token to be targeted, and prefer templated content over fully agent-composed free text. Push notifications typically require a device token obtained through the app's own registration flow, which is itself outside MCP's scope; the MCP tool just triggers a send once that token is already on file.
Format & Payload Metadata
Format: Push-provider-specific API (FCM, APNs)
Latency: Typically hundreds of milliseconds to a few seconds for delivery
Real-World Implementation Use Case
An MCP tool sends a push notification via Firebase Cloud Messaging to the requesting user's own registered device when a long-running task completes, using a fixed template rather than agent-composed text.
