Cursor Extension Integration
Integrate VS Code extensions with Cursor IDE. Covers the Open VSX Registry, VSIX installation for Microsoft-exclusive extensions, conflict resolution with AI features, and recommended extension stacks.
Extension Marketplace: Key Difference from VS Code
Cursor uses the Open VSX Registry instead of Microsoft's VS Code Marketplace. This is because Microsoft's marketplace terms restrict access to VS Code products only.
Impact: Most popular extensions are on Open VSX. Some Microsoft-published extensions are not.
Or right-click an extension > Disable (Workspace) to disable only for the current project.
Extension Settings Sync
Cursor does not sync extensions between machines automatically like VS Code Settings Sync. To transfer:
# Export extension list
cursor --list-extensions > cursor-extensions.txt
# On new machine, reinstall all
while read ext; do cursor --install-extension "$ext"; done < cursor-extensions.txt
Enterprise Considerations
Extension allow/deny lists: No built-in mechanism in Cursor. Enforce via documentation and team policy.
VSIX vetting: Review VSIX files before distributing to team (check for telemetry, network calls)
Open VSX vs Marketplace: Some extensions have different publishers on Open VSX. Verify publisher identity.
Extension updates: Extensions auto-update from Open VSX. VSIX-installed extensions do NOT auto-update.
