Est-ce que com.professorsausages/sausage-onchain est sûr ?

Au dernier audit MCP Hub, le serveur MCP « com.professorsausages/sausage-onchain » est classé « Non encore testé ». Référencé dans l'annuaire. Seul le pentest comportemental fait foi, et il n'a pas encore été exécuté sur ce serveur. Le verdict est réévalué en continu ; consultez la fiche pour l'état à jour.

Méthode : MCP Hub analyse la description de chaque outil (couche 1) et, pour le verdict fort, exécute le serveur dans une micro-VM isolée avec leurres et réseau bloqué (couche 2). On publie des noms et des compteurs, jamais le contenu brut renvoyé par un outil.

Les 12 outils

• address_screen≈ 306 tokens

  Screen a crypto address against the full live OFAC SDN list, segmented by chain. Returns a verdict with the matching SDN entries as evidence — never a silent all-clear. Paid: call without x_payment to receive this call's exact terms (amount, asset, network), sign them, then call again with x_payment. The free `pricing` tool lists every price at once.
