The management save/update body takes is_private, author_user_id and
share_user_ids (absent keeps each; a new material gets the caller as
author), and the managed material shows them. New routes PATCH
/materials/{id}/visibility, PUT /materials/{id}/shares and GET /users,
with the MCP tools bm_manage_set_material_visibility,
bm_manage_set_material_shares and bm_manage_list_users. The /bmadmin
form gets the private switch, the author picker and shared_with.
- 28 typed tools over /api/v1/bm: list, show, create and update for
courses and meetings, plus delete for class sessions, readings,
deadlines and materials (save upserts on title and course)
- inputs mirror Fillable and Rules; enums, lengths and date formats in
the field descriptions; no seed, me or dry_run tool
- materials accept meeting_id (absent keeps, null clears, must exist)
and the managed material JSON shows it
- README: MCP tools section
