Bugbot - cursor mentions in PR comment threads not working (GitHub Enterprise)

Support Help

Hi there!

I’m working on a repository in GitHub Enterprise with a bugbot integration through a corporate Cursor account.

What works: The automated review integration is working fine. Cursor successfully adds inline comments pointing out issues in the code.

The issue: When I try to interact with Cursor in the thread of one of those comments using @cursor, I get the following error:

Unable to authenticate your request. Please make sure to connect your GitHub account to Cursor. Go to Cursor

What I’ve tried: In addition to the team-level integration, I connected my personal GitHub account directly via Dashboard > Integrations. After doing this:

  • Automated reviews still work as expected

  • When I mention @cursor in a comment thread, the response changed to “Taking a look!”, but nothing happens after that. No follow-up response ever comes.

If I comment “cursor review” outside of the comment threads (e.g., in the main PR conversation), it triggers a new review normally.

Questions:

  1. Is this supposed to work?

  2. If so, any suggestions on what might be causing this issue?

Thanks in advance for any help!

Hey, thanks for the detailed report.

The supported ways to manually run Bugbot are:

  • Leave a cursor review or bugbot run comment in the main PR conversation
  • Automatic reviews when the PR is updated

Tagging @cursor in threads with inline comments may currently be supported only in a limited way. It’s not clearly listed in the docs as a supported trigger. Still, the fact that it replies “Taking a look!” suggests it partly recognizes the mention but doesn’t actually run, which sounds like a bug.

To help us investigate, could you share:

  1. A link to the PR where this happened (or the repo name)?
  2. The approximate time of your last attempt (date and time)?

For now, the reliable workaround is to use cursor review in the main PR conversation to trigger a review.
