What is "mdc:" link schema?

What is mdc: link schema in Cursor?
Not .mdc file, but mdc: link schema in .mdc rule files. For example: [filename](mdc:filename) syntax.
I’m just trying to understand why this prefix can’t be dispensed with?
And that it has one problem - it breaks the URL of the link.

I have similar problems - this kind of override keeps popping up automatically and breaking links.

Here is an example of a broken URL caused by a Cursor in a *.mdc file:

- **Detail Planning (Detailplaneeringud)**: [https://gis.sauevald.ee/arcgis/rest/services/Detailplaneeringud](mdc:https:/gis.sauevald.ee/arcgis/rest/services/Detailplaneeringud)

I created a bug report: Cursor Incorrectly Modifies URLs in .mdc Files by Adding 'mdc:' Prefix
