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,
