Roster is an Administration view for monday.com. It pulls together the access picture that monday shows across separate screens — board ownership, subscribers, team routes, and guest presence — into one list, with the risky patterns flagged.
Coverage limit
Even for an account admin, monday's API does not return private boards the admin is not a member of. There is no superuser token that reads every board on an account — a token reflects the same access as the person who owns it.
Roster can see: main (public) boards, shareable boards, and private boards the signed-in admin is personally a member of. It cannot see private boards outside that set, and it says so on screen rather than presenting a partial view as a complete one.
In practice this rarely hides the risky patterns above — everyone-permission boards, stray guests, and owner sprawl tend to live on public and shareable boards, which Roster does cover. A closed private board, by its nature, is already closed to everyone outside it.
