The Cursor button in the github repo doesn't seem to work - when clicked, it opens a new tab with the pictured URL and doesn't route to Cursor like the VS Code button does.

It should link to cursor://anysphere.cursor-deeplink/mcp/install?name=MongoDB&config=eyJjb21tYW5kIjoibnB4IC15IG1vbmdvZGItbWNwLXNlcnZlciAtLXJlYWRPbmx5In0%3D

Likely reason why is that it's a cursor:// link and GitHub ignores non-HTTP links. This is the case for my link above too which is actually has a markdown link to itself but is ignored.
