Est-ce que com.ducktax/ducktax est sûr ?

Au dernier audit MCP Hub, le serveur MCP « com.ducktax/ducktax » 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 20 outils

• categorise_transactions≈ 302 tokens

  Categorise bank-statement transaction descriptions into the fixed vocabulary this product maps to balance sheet lines (sales, software, owner-in, …). Send description strings only, never amounts or dates. Sum the amounts per returned category yourself, then call totals_to_figures. One statement import is one quota unit; previously seen descriptions are answered from a shared cache free.

  Paramètres, retour & exemple (2)

  Paramètres

  • tradingType · string · requis
    What the company does, to resolve ambiguous merchants. One of: software, consulting, creative, retail, construction, property, hospitality, other. lookup_company suggests one from the SIC codes.
  • descriptions · array · requis
    The raw description strings, one per transaction.

• check_accounts≈ 992 tokens

  Derive a small-company balance sheet (micro-entity, in UK terms) from raw figures and validate it. Returns the derived sheet for the current and prior year, the figures the authority would reject (negatives where it wants a positive, share capital left at nil), and whether they are complete enough to hand to a filing product. It does NOT check that the sheet balances and cannot: retained earnings is derived as the balancing figure, so both sides always agree. Do not tell anybody their sheet was checked for internal consistency. Free and instant: call it after every change to the figures. All money in major units (pounds not pence, dollars not cents). Pass lastFiledAs from lookup_company and it also warns when figures showing activity are about to be filed dormant again.

• check_filing_extension≈ 573 tokens

  Whether a company can still apply to its registrar for more time to file, how many days are left to apply, and what being late costs if that window is missed. This is usually the most useful thing to tell somebody who has just found a deadline: applying is free, takes about 15 minutes, and has to be done BEFORE the deadline it extends, so the option expires on the same day the penalty starts. Returns nextAction first. It PREPARES an application and can never submit one: the application is made by a director on the registrar’s own service, which this tool links to. It does not file accounts. Give a company number to read the deadline off the register (quota-charged, cached results free), or give the dates yourself and it costs nothing.

• dormant_figures≈ 197 tokens

  The complete set of figures for a dormant company: share capital, the matching cash, and zeros everywhere else. The register says when the last accounts were filed dormant, and for those companies this collapses the whole form to one call. Amounts in major units.

• draft_extension_reason≈ 436 tokens

  Turn a short factual account of what went wrong into the reason text for an application for more time to file accounts, framed in the terms the registrar actually applies. It uses only the facts you give it: it will not invent circumstances, and where something is missing it leaves a bracketed placeholder rather than filling it in. The person must check every sentence before using it, because they are certifying it to the registrar. Ask them what happened, do not supply it yourself. This tool does not submit the application and does not file accounts. Quota-charged as an explanation; identical input is answered from cache free.

  • jurisdiction · string · requis · GB | IE | US | AU
    ISO country code. Register access exists for GB and AU.
  • circumstances · string · requis

• save_filing≈ 1013 tokens

  Save a set of figures to the user's account, or update a saved one by passing its id from list_saved_filings. Figures in major units. The filing is saved even when validation finds problems, because a work in progress is worth keeping, and the problems come back in the response so you can raise them.

  Turn categorised bank-statement totals into balance sheet figures, applying the rules that stop an import lying: only income categories reach turnover, only expense categories reach operating costs, and the owner topping up the account is never sales.

• track_company_deadlines≈ 482 tokens

  Watch a company by its register number and get reminded before its filing deadlines. Which channels are actually available depends on the server: the reply reports what will really be sent, and it can be nothing at all, so read it rather than assuming. No saved filing is needed: this is for the deadline itself, which matters months before any figures exist. Reminders go out on a ladder of days before the deadline (default 90, 60, 30, 14, 7, 1), and each one states the company, the deadline, the date, the days remaining and the penalty for missing it. Calling this again updates the settings and un-mutes a company that was untracked.

  Paramètres, retour & exemple (5)

  Paramètres

  • push · boolean · requis
    Send reminders as web push to signed-in browsers.
  • email · boolean · requis

    ISO country code. Deadline reminders exist where the register publishes deadlines.
  • companyNumber · string · requis
    The register identifier: GB company number (e.g. 15379140) or AU ABN.
  • remindDaysBefore · array · optionnel
    Days before the deadline to warn, e.g. [60, 14, 1]. Omit to use this server’s default ladder. Only the tightest rung that applies is ever sent, so a long ladder does not mean a burst of messages.

• untrack_company_deadlines≈ 238 tokens

  Stop sending deadline reminders about a company. This mutes rather than forgets, which is the only thing that holds: a company implied by a saved filing would otherwise be re-added by the next scan. track_company_deadlines un-mutes it again.
