It is possible to use it from other plugin by the following way.

Example

---

require MT;
my $app = MT->instance;
my $dumper = $app->component('Dumper');
my %config_hash = (
'dump_entry' => 1,
'dump_entry_yaml' => 1,
'dump_entry_yaml_file' => 'entries.yaml',
'dump_entry_fields' => {
'id' => 'id',               # Outout id field.
'title' => 'name',          # Output title field as name.
'permalink' => 'permalink', # Output Permalink.
'entry_email' => 'email',   # Output Custom Fields field that specified by tagname.
},
);
foreach my $k (keys %config_hash) {
$dumper->set_config_value($k, $config_hash{$k}, 'blog:1');
}

出力例(entries.yaml)
