• Todas as ferramentas passam nas seis verificações.

Um programa verifica o servidor uma vez por dia: initialize e tools/list, sem modelo. Os tokens são o tamanho das definições, a cerca de quatro caracteres por token. A nota é a média de seis verificações do nome, da descrição, do esquema e das anotações de cada ferramenta; diz se as ferramentas estão bem descritas, não se funcionam. A nota pesa só o que foi medido: se responde (30%), se faz o trabalho do produto (25%), definições (20%), contexto (10%) e uso (15%). Uma parte não medida fica de fora, e uma instrução oculta limita a nota a 40. O estado dos servidores MCP dos fornecedores: método e números →

• list_series

  Included. What this engine covers, the publisher and as-of date behind each series, and the no-guess rule.

• route_claim

  Included. Shows which series a claim would be routed to, the value and date extracted, and the signals behind the score. Returns NO verdict — pay for check_figure when you want one.

• list_card_packages

  Included. The one-off card packages as one machine-readable catalogue: the 11 products and their 13 prices in Australian dollars, the unit one payment buys for each SKU, what the package returns, and where the input is sent. One payment…

• buy_card_package

  Included. Opens a Stripe Checkout Session for one card package and returns its payment link and its session id. This tool charges nothing and produces no artefact: on the card rail the thing that taps is a human. The package's work runs…

• check_figure

  Submit the dated figure you are about to act on. Returns verified, stale, contradicted or unknown, cited to the publisher's own series with its as-of date. Relevant wherever a number is going onto a page, deck or decision. Not advice…

• check_entity

  Verify a legal entity: does this company exist, under which identifier and jurisdiction, and is its registration current? Cited to open primary registers (the GLEIF LEI index and US SEC EDGAR). Returns found, ambiguous, not_found or…

• check_entity_file

  The entity file: ONE paid answer holding everything we hold about one company: the whole picture in ONE call rather than four separate facts stitched together, at the point of signing, onboarding, paying or acquiring a counterparty. It…

• check_entity_file_il

  Israeli company lookup and company register check by company number (nine digits, with its own check digit) or by registered name, Hebrew or English: identity, corporation type, the register's own status and sub-status, description and…

• check_entity_file_ca

  Canadian company lookup and Canadian federal corporation register check by nine-digit Business Number (BN) only: corporation number, BN, governing legislation, every registered name with type, current flag and effective date, the…

• check_sanctions

  Sanctions screening of a name, for whether a person or company is on a sanctions list — and which one. Reads OFAC SDN, the UN consolidated list, the EU Financial Sanctions File and the UK Sanctions List, and returns listed, mismatch…

• check_vat

  An EU VAT number check — VAT validity, and the VAT registration behind it. Reads the official VIES service (European Commission), keyless. Returns valid, invalid or unknown — an outage is NEVER reported as invalid — with the member state…

• verify_citation

  Says whether a citation can be repeated. Submit a DOI, an arXiv ID or a paper title: returns whether it exists, what it is (title, authors, year, container) and whether it has been retracted, cited to Crossref and arXiv. Optionally send…

• verify_package

  Reports on a dependency at the point of installation. Submit a package and version plus its ecosystem: returns whether that exact version exists, whether it is yanked or deprecated, and every advisory OSV lists against it. An invented…

• watch_add

  Watch ONE citation or ONE package version instead of checking it once. Send kind ('citation' or 'package') and the subject (a DOI, an arXiv ID or a title; or npm:[email protected]). The first check is answered immediately and signed, then…

• watch_portfolio

  Watch a whole list instead of one reference at a time: up to 25 citations or package versions re-checked every day for 30 days under one token. US$5 a portfolio — 20 cents a reference, under a cent a check — and the first check on every…

• verify_bulk

  Check a whole list in one call: a bibliography or a dependency manifest. Send items[] of {tool, input} or the citations[]/packages[] shorthand. Up to 12 items at a flat US$0.12 on this door; longer lists pay 0.016667 an item on the…

• check_document

  A whole document in one call: the claims that can be verified against a primary source, each answered by the door that owns it with its own signed receipt, plus one receipt over the document. Extraction is mechanical, so the claim list…
