Your Mastra Agent Now Has an Inbox With Priority Notifications

You can connect external sources like GitHub, Slack, Sentry, Datadog, and have your agent act on emitted events using Mastra’s signal system. These events are durable and they have priority.

Agent notification inboxes and priority signals let you build more attentive agents. An AI SRE agent could wake up and try to auto-remediate a 5XX error from Datadog. A personal assistant agent could text you when it receives urgent email in your inbox.

This is not an email inbox though stay tuned.

Before this, you could inject context into an agent’s memory thread using sendSignal(), but there wasn’t a standard shape for durable records, priority-aware delivery, or a tool agents could use to read notifications and action high priority items.
