Cursor cloud agent can't see our alert notifications

Where does the bug appear (feature/product)?

Cloud Agent (GitHub, Slack, Web, Linear)

Describe the Bug

The Cloud Agent can’t see Slack notifications sent by our monitoring app, i.e., notifications from AlertManager (Victoria Metrics).

Steps to Reproduce

Tag @cursor, or use a Cursor Automation with the read_slack_messages tool and ask it to look at messages in a Slack channel that has alerts from AlertManager. It cannot see the messages. It can see other messages in the channel sent by humans and can also see notifications sent by 3rd party integrations such as Sentry and Mixpanel.

Expected Behavior

The Cursor agent should be able to see all notifications in a channel

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey @Shahar_Barak!

What you’re seeing isn’t a Slack permissions problem - it’s on our side. Some alert apps (Alertmanager / Victoria Metrics style) put the alert body in a message format our Slack reader doesn’t currently extract, so those posts get dropped even though human messages and apps like Sentry/Mixpanel show up fine. This is something we’ve seen before, and it’s an issue we’re tracking.

Until that’s fixed, the most reliable workarounds are:

  1. Use a Slack Workflow (or similar) to re-post the alert text as a normal plain message into the channel (or a companion channel) that @Cursor / your automation reads
  2. When you @Cursor in an alert thread, paste the alert body into your message so the agent has the content directly

I’ll post here when there’s an update. Slack setup docs for reference: Cursor Slack integration
