Extensions temporarily disappearing from Cursor Marketplace

Hi team,

We’ve been seeing cases where some extensions temporarily become unavailable in the Cursor Marketplace, even though they are still present and downloadable from Open VSX.

This has shown up in our CI (where extension installs occasionally fail), but we’ve also observed the same behavior directly in the Cursor IDE UI: extensions that were previously available simply don’t show up or can’t be installed, and then reappear later without any changes on our side.

Examples of affected extensions include:

  • yzhang.markdown-all-in-one, which was unavailable for some time around Dec 23rd but is now back

  • redhat.vscode-xml, which was unavailable for some time around Dec 30th but is now back

  • github.vscode-github-actions, which is unavailable as of writing this (Jan 2nd)

Here’s what the error message looks like:
❯ cursor --install-extension github.vscode-github-actions
Installing extensions…
Extension ‘github.vscode-github-actions’ not found.
Make sure you use the full extension ID, including the publisher, e.g.: anysphere.csharp
Failed Installing Extensions: github.vscode-github-actions

What’s interesting is that during these windows, the extensions remain available on Open VSX, which suggests this is not an upstream removal. This made us wonder whether this could be due to some form of caching, synchronization delay, rate limiting, moderation/copyright checks, or other filtering on the Cursor marketplace side.

We’re considering switching to installing pinned .vsix files directly from Open VSX to make things more deterministic, but wanted to check first:

  • Is this kind of temporary unavailability expected or a known issue?

  • Are there best practices for ensuring reliable extension availability, especially for automated or reproducible setups?

Thanks in advance for any insight — happy to provide examples or logs if useful.

Best,

Thank you for this detailed report. Extensions should not be flaking like this. We are looking into it.

I can confirm this issue. I faced the same problem when trying to install Github action extension.

This issue should be fixed – please let us know if you continue to see extensions disappearing that were previously visible.

I had issues installing the DevContainers extension, but today it stopped being an issue.

@ravirahman

We just experienced this with tooltitudeteam.tooltitude-pb extension. It was available yesterday, and today, it disappeared.


I get it with Console Ninja too. Happened before with Dev container.

Even worse when I try to install a VSIX manually I cant even select it in the finder after downloading it

Always something like SimpleURLLoaderWrapper.

This should have been fixed a while ago IMO not particuarly happy

@tooltitude @Peter_Cox Apologies for these issues; there was an issue with our security scanning that incorrectly flagged Console Ninja and ToolitudePb. These extensions should be visible on the marketplace.

@ravirahman I just released a new version, and the build disappeared again.

@ravirahman If there’s a way to send you a private message, I could send you information about what I found out about this so far.

Thanks for the speedy fix, I can now install it again!
