This module blocks configured queries that change server state.
E.g. to make vCard storage read-only:
= {
readonly_stores = { "vcard-temp", "vCard" };
vcard }
With the plugin installer in Prosody 0.12 you can use:
sudo prosodyctl install --server=https://modules.prosody.im/rocks/ mod_readonly
For earlier versions see the documentation for installing 3rd party modules
