Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. The “Just a moment…” page indicates that Epic Games’ documentation site uses Cloudflare bot protection, which blocks Cursor’s indexing crawler.

However, Unreal Engine documentation is already built into Cursor.

1. Open Chat and type @
2. Look for Unreal Engine in the suggestions

If the built-in documents don’t include the Python API version you need (5.6), please let me know and I’ll pass it on to the team.

Hi deanrie,
I tried and built-in @UnrealEngine doc don’t have python content.
