I finally added the namespaces in the rule and everything is working accordingly :

def main():
    """add a swrl rule."""
    parser = argparse.ArgumentParser()
    parser.add_argument("--ontology", help="ontology file", required=True)
    parser.add_argument(
        "--destination", help="destination ontology file", required=True
    )

    args = parser.parse_args()

    input_file = args.ontology
    output_file = args.destination

    onto = owl.get_ontology(input_file).load()

    with onto:
        swrl_rule = """ http://maccve/onto#Machine(?m) ^ http://maccve/onto#Package(?p) ^ http://maccve/onto#CVE(?c) ^ http://maccve/onto#mcontains(?m, ?p) ^ http://maccve/onto#has_CVE(?p, ?c) -> http://maccve/onto#contains_CVE(?m, ?c) """

        rule = owl.Imp()
        rule.set_as_rule(swrl_rule)
        onto.save(file=output_file, format="rdfxml")

if __name__ == "__main__":
    main()
