Awesome! Two things:

1. Let's link this to an issue. Either one in the backlog or let's create a new one describing the work (for traceability).
2. The official title is "Open MCT" (2 words). I left a suggestion in the review.

Thanks for this! It should be good to merge once those two issues are addressed.
