You can install an empty service, one that does not actually run anything. This is often called a 'recipe about nothing'. It should look something like this:

service {
    name "empty"
    type "WEB_SERVER"

    lifecycle {

        locator {
            NO_PROCESS_LOCATORS
        }
    }

}

Add your custom commands here and you can run them from the Cloudify CLI/REST API as usual. Note the use of the NO_PROCESS_LOCATORS directive - this tells the USM not to perform any process liveness scans.
