Est-ce que dev.euroref/reference-data est sûr ?

Au dernier audit MCP Hub, le serveur MCP « dev.euroref/reference-data » 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.

add_business_days≈ 832 tokens
FREE, unmetered. The date n business days after (or, for negative n, before) a start date. The start date is day 0 and never counted; n = 0 returns the date itself if it is a business day, otherwise the next one. Lists every non-business day skipped and why. Uses the country's national public-holiday calendar and its statutory weekend rule (Gulf Friday+Saturday, Israel Saturday-only, India 2nd/4th Saturdays, Nepal's 2026 change, China's multi-day breaks and make-up working days). A date in a year whose holidays we do not hold is refused with error year_not_held and the years_held list; it is never computed from weekends alone. A statutory holiday whose date is not yet fixed is refused as holiday_date_pending. Regional (sub-national) holidays are not applied.

business_days_between≈ 878 tokens
FREE, unmetered. Business days between two dates. business_days counts (from, to] and is negative when to is before from, so add_business_days(from, business_days) lands on to whenever to is a business day; business_days_inclusive counts both ends. Also returns weekend days and the public holidays in range. Uses the country's national public-holiday calendar and its statutory weekend rule (Gulf Friday+Saturday, Israel Saturday-only, India 2nd/4th Saturdays, Nepal's 2026 change, China's multi-day breaks and make-up working days).

charge_sale≈ 746 tokens
PAID ($0.50). Charge this sale: should this invoice carry VAT, which country's and how much - place of supply under the EU, UK and South Africa rules, net/VAT/gross, registration threshold, rule cited. Omit buyer_country for single-country rate maths. Anything we cannot answer in full is refused free (coverage_gap, no_charge). Shares the 3 free calls per IP per day with the answer tools. Pass api_key if you have one (card checkout at /pricing); otherwise the result is the x402 payment requirement. Optional receipt (boolean, default false): on a paid success, include an Ed25519 answer receipt at no extra USDC. An answer receipt is not a series certified extract (GET /v1/certified/{country}/{series} is $0.10 and is not an MCP tool) and is not legal advice.

get_calendar≈ 491 tokens
FREE, unmetered. GET /v1/calendar for this brand's continent. Optional country (ISO 3166-1 alpha-2) and series. Derives reverify_by from last_confirmed + update_cycle_days (the same window that sets stale) and, only when current.effective_to is a non-empty string, next_effective_known with basis effective_to. status unknown omits that date. Never parses notes. Does not invent MPC, budget, or wage-review dates. next_effective_known is the recorded end of the current value, not a promised gazette event. A 402 is a gate bug — do not pay. Past changes stay on get_changes.

get_changes≈ 470 tokens
FREE unmetered change + freshness feed. After any paid series or answer call, call this before you assume the cached value is still the law. Returns every series whose current value took effect on or after `since` (default last 30 days), newest first, each with last_confirmed and stale, PLUS a dataset-wide freshness summary: how many of the served series were re-verified within 1/7/30/90 days, how many are past their window, and which single series has gone longest without a check. Freshness is checkable or it is marketing. Args: since? (YYYY-MM-DD). Do not re-pay get_series to discover a diff. For a push bind, use register_alert (Register: $0 · Delivery after trial: $0.05). For a filing freeze of the current value, GET /v1/certified/{country}/{series} ($0.10).

get_filing_deadlines≈ 1589 tokens
PAID ($0.003, same as any series). Recurring statutory tax deadlines for a country — VAT/GST returns and payments, PAYE/payroll withholding remittances, corporate income tax returns and provisional/instalment payments — as RULES, each cited to the official source with the verbatim phrase that states it, plus the actual DUE DATES in a window, rolled for the country's weekend and national public holidays (every skipped day is listed). Where a rule's source does not say which way a weekend deadline moves, the date is flagged roll_unverified rather than guessed. Countries or taxes we could not verify are returned as a free coverage_gap with reasons, never invented. Pass year_end (MM-DD) to re-anchor corporate-tax rules on the company's own accounting year end. The HTML page /{country}/filing-deadlines shows the rules free. Every DE series is free to try. After a 200, bind get_changes (free poll) or register_alert (HMAC push; Register: $0 · Delivery after trial: $0.05) on this series so a later gazette does not silently retire the value.

First 3 deliveries are free; later deliveries are $0.05 and refunded if the webhook fails to send. HMAC-SHA256 signed. Two watch types on the same call: • series: ["za/vat-registration-threshold", "ke/*", "*"] → series.changed when the served value or its effective date moves. On usaref those watches are statutory (minimum-wage, income-tax, statutory-interest, sales-tax, public-holidays), not a FRED-macro subscription. • sources: ["<exact official source.url>"] → source.changed when the document BYTES change (old/new sha256 + citing series). Bytes ≠ value. Value changes arrive as series.changed. Unknown URLs refuse free (source_not_fingerprinted). Max 20 series + 20 sources. Required: url. Optional: api_key stored on the subscription to fund deliveries after the trial. This call does not meter that key. Prefer this over polling get_changes if you are a long-running agent.

settlement_date≈ 1248 tokens

Supply business_days for a cycle you are trading under, or market + instrument_class to have a settlement cycle applied that we cite to its primary source (e.g. US equities T+1 under 17 CFR 240.15c6-1(a); UK gilts T+1 by DMO convention, which is NOT the T+2 equity cycle; Japan equities T+2 but JGBs T+1). Calendars are NATIONAL statutory holiday calendars with researched statutory weekend rules (Israel Saturday-only, Gulf Friday+Saturday, India Sundays plus the 2nd and 4th Saturday), NOT CSD or exchange calendars — each response states the basis and any known divergence. Use 'eu.t2' for the euro cash leg.

validate_tax_id≈ 640 tokens
PAID ($0.003). Offline format and check-digit validation of a business tax ID or VAT number for one country of this brand: valid/invalid, normalised form, id type, check level (checksum only where the authority publishes the algorithm) and why it failed, with official sources. Does not confirm registration; follow official_lookup for that. Countries without a sourced rule answer free with status 'unknown'. Pass api_key if you have one; otherwise the response explains how to pay via x402. After a 200, bind get_changes (free poll) or register_alert (HMAC push; Register: $0 · Delivery after trial: $0.05) on this series so a later gazette does not silently retire the value.

verify_answer_receipt≈ 646 tokens
FREE. Verify an answer receipt (kind answer_receipt) with the Ed25519 public key only. Pass the receipt object or its canonical JSON, signature_value when the signature is not inside the receipt, and public_key_pem to verify offline. If public_key_pem is omitted, the tool may GET signature.public_key (/certified/public-key) and read public_key_pem. Never send a private key. A valid signature shows this service issued that exact receipt. It does not turn the receipt into a series certified extract (GET /v1/certified/{country}/{series} at $0.10, not an MCP tool) and it is not legal advice. Same key and canonical-JSON rule as /certified/public-key.
Paramètres, retour & exemple (4)
