Au dernier audit MCP Hub, le serveur MCP « tax.terminal/filing » 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.

• continue_filing_session≈ 1010 tokens

  Checks the taxpayer's completed draft packet for a federal return and, when it passes, holds it as an unsigned draft and returns the link to the filing page; otherwise returns a list of problems to correct. This call files nothing and sends nothing to the IRS: the taxpayer reviews, signs and files personally on the filing page. Takes the filing session's continuationHandle, completedReturnPacketJson (the whole packet as one JSON string, in this server's packet schema) and packetSchemaSha256 (that schema's digest); any other argument, including a schema argument, is refused by name. The packet holds only facts the taxpayer stated in this chat and figures printed on documents the taxpayer gave in it. The tax year is return.taxYear=2025 inside the packet. Returns status filing_session_ready with one filingSessionUrl when the packet is accepted: the only response that contains the link, which the taxpayer opens to give permission, review the return and sign it. Otherwise returns blockers, each with a path, a rule and a plain detail, and no link: that packet is not kept, every blocker that can be checked arrives in one response, a check that depends on a missing or refused answer runs once that answer is corrected, and the same handle accepts a corrected packet. The packet is accepted, and on the packet-first order the filing link issued, only when it holds every item the return and the filing page need from this conversation, the agentIdentity section included (where the link came first, the filing page waits for that accepted packet); each missing item comes back as its own blocker naming its path and the exact question for the taxpayer, all in one response, and only what the law has the taxpayer enter personally, the review and the signature are left for the filing page. A link left unopened for 15 minutes lapses, and sending the same packet again returns a new one. An accepted packet is held until the taxpayer gives permission on the filing page; declining there, or expiry, erases it. Federal only: no state, territory or local return is filed. The return has no taxpayer identity fields: the taxpayer's own details go only in the packet's separate, required agentIdentity section, which the filing page shows for the taxpayer to confirm. Business identifiers printed on each source form, such as an employer's or payer's name and EIN, are packet fields. The filing session's status reports progress.

• get_filing_status≈ 1457 tokens

  Answers a taxpayer's question about the filing created through this service: reads ordered, status-only results for every jurisdiction in its one current Terminal Tax filing. IRS results appear only for a filing whose taxpayer signed the optional status-sharing consent on the filing page; otherwise the status is results_emailed, and Terminal Tax emails the results to the taxpayer. Takes the filing session's continuationHandle, or no arguments under the legacy OAuth grant. Reads no return content, payment data, identity, raw IRS rejection text or filing history.

• get_packet_schema≈ 1410 tokens

  Takes the filing session's continuationHandle. Returns the packet schema a completed return packet is checked against (the packet holds no Social Security number, ITIN or PIN: the taxpayer types those on the filing page): requestPacketSchema=true returns the schema digest (packetSchemaSha256, sent with the completed packet), an outline whose larger parts are named sections, the section list and the packetStarterTemplates list; packetSchemaSection=<name> returns one section and packetStarterTemplate=<id> one complete starter packet, in which each taxpayer-specific value is the placeholder REPLACE_WITH_TAXPAYER_VALUE, refused by path until replaced, with its askTheTaxpayer messages (the questions for the taxpayer) and each preset answer listed in presets with how it is settled. Read-only: no tax facts are sent here and no return is written. The tax year is return.taxYear=2025 inside the packet, not a tool argument; any other argument is refused by name.
