Sometimes, especially on public services, you may want to allow people to create their own rooms, but prevent some options from being modified by normal users.

For example, using this module you can prevent users from making rooms persistent, or making rooms publicly visible.


You need to supply a list of options that will be restricted to admins. Available options can vary, but the following table lists Prosody’s built-in options (as defined in XEP-0045):

Name Description
muc#roomconfig_roomname The title/name of the room
muc#roomconfig_roomdesc The description of the room
muc#roomconfig_persistentroom Whether the room should remain when empty
muc#roomconfig_publicroom Whether the room is publicly visible
muc#roomconfig_changesubject Whether occupants can change the subject
muc#roomconfig_whois Control who can see occupant’s real JIDs
muc#roomconfig_roomsecret The room password
muc#roomconfig_moderatedroom Whether the room is moderated
muc#roomconfig_membersonly Whether the room is members-only
muc#roomconfig_historylength The length of the room history

Some plugins may add other options to the room config (in Prosody 0.10+), for which you will need to consult their documentation for the full option name.


Enable the plugin on a MUC host (do not put it in your global modules_enabled list):

Component "" "muc"
modules_enabled = { "muc_config_restrict" }
muc_config_restricted = {
  "muc#roomconfig_persistentroom"; -- Prevent non-admins from changing a room's persistence setting
  "muc#roomconfig_membersonly"; -- Prevent non-admins from changing whether rooms are members-only


trunk Doesn’t work (uses is_admin)
0.12 Works?


With the plugin installer in Prosody 0.12 you can use:

sudo prosodyctl install --server= mod_muc_config_restrict
