Au dernier audit MCP Hub, le serveur MCP « io.github.everyai-com/fee-fighter » 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 4 outils

• annual_cost≈ 749 tokens

  Project the cumulative cost of a fee list over 1-30 years by straight multiplication of each recurring fee's annualized amount, with one-time fees counted once (no compounding or inflation), with a per-fee breakdown. Use for 'what will these cost me over N years'. It does not flag fees: use audit_fees to find problem charges, benchmark_fees for typical ranges.

    Non-empty list of fees to project, each {name, amount, frequency, category?}; category is accepted but not used here

• audit_fees≈ 813 tokens

  Audit a list of fees: annualize each one (monthly x12), total the yearly cost and monthly average, and flag charges above the typical US range for their category, duplicate names and one-time fees of $30+ worth disputing. Use when the user lists fees to review. For a multi-year projection use annual_cost; for typical ranges alone use benchmark_fees.

• benchmark_fees≈ 687 tokens

  Look up typical US consumer fee ranges (min/max per charge, USD) for one category such as bank_overdraft, or the full 14-category table when category is omitted. Use to answer 'is this fee normal?' questions. To check a user's own list of fees against these ranges, use audit_fees.

  • category · string · optionnel
    Category key (case-insensitive; spaces/hyphens become underscores), one of: bank_overdraft, bank_monthly_maintenance, atm_out_of_network, late_payment, gym_membership_monthly, streaming_monthly, airline_checked_bag, airline_seat_fee, ticket_convenience, rental_application, subscription_app_monthly, delivery_fee, airline_change_fee, hotel_resort_fee. Omit to get the full table; an unknown key returns an error listing valid keys.
