概覽

AI 產生的概覽

一個託管驗證套件，讓助理按次付費驗證歐盟增值稅號、IBAN、電子郵件地址、地名和車輛識別碼。

可以做什麼: 驗證歐盟/歐洲經濟區增值稅號，進行格式與校驗和預檢並即時查詢 VIES，回傳註冊狀態及可取得的公司資訊。離線驗證 IBAN 的長度、mod-97 校驗和、國家與銀行識別碼。檢查電子郵件地址的語法、即時 MX 記錄、一次性網域和角色地址。將地名或國家/州/城市輸入解析為正規化名稱、ISO 代碼、層級、人口和座標。解碼 VIN，進行校驗位驗證並透過 NHTSA vPIC 完整解析品牌、車型、年份和引擎。
適用情境: 適合助理需要快速、權威地驗證增值稅號、IBAN、電子郵件、地點或車輛 VIN 等業務識別碼時，例如清理客戶或供應商資料、檢查表單輸入。
執行需求: 遠端 streamable-HTTP 端點 valid.fabtally.com，或透過 npx 執行本機 npm 套件 fabtally-valid-mcp。不需帳號或 API 金鑰，但每次工具呼叫都需透過 x402 以 Base 上的 USDC 付費；未付費的呼叫會回傳付款挑戰。可用 FABTALLY_VALID_BASE 設定選用的基礎位址。

安裝前請注意

每次呼叫都收費，透過 x402 付款載荷以 Base 上的 USDC 結算，助理可能在使用者未明確要求時產生支出。增值稅查詢會把號碼傳送給官方 VIES 服務，電子郵件檢查會把網域傳送給 DNS，VIN 解碼會傳送到 NHTSA vPIC API。結果不構成法律、稅務或財務建議。

安裝

在 SourceWeft 中

README

FabTally Valid — MCP server

A developer validation suite — the per-call utilities incumbents charge for (Vatstack $0.01–0.09/call) or lock behind subscriptions, unified. Fronts the Valid HTTP API at https://valid.fabtally.com. Holds no private key.

Tools (all paid; a call with no payment returns the decoded x402 402 challenge)

Tool	Price	What it does
`validate_vat`	$0.003	Flagship. EU/EEA VAT: `{country_code, vat_number}` → per-country format + checksum pre-check AND a live VIES lookup, returning valid/registered plus the registered company name & address when VIES has them (cached ~1h to shield the flaky VIES).
`validate_iban`	$0.001	`{iban}` → ISO 13616 length + mod-97 checksum, country, human-formatted grouping, and bank identifier (German Bankleitzahl, UK bank code + sort code, …) extracted from the BBAN where derivable. Pure-offline.
`validate_email`	$0.002	`{email}` → RFC-ish syntax + live MX-record (DNS) existence + disposable/throwaway-domain detection (bundled blocklist) + role-address flag (`info@`, `admin@`). Stateless & non-PII: the address is never stored and no SMTP mailbox is probed.
`geo_lookup`	$0.002	`{query:"Munich, Bavaria, Germany"}` or `{country,state,city}` → normalized names, ISO 3166-1/-2 codes, country→subdivision→city hierarchy, population and coordinates, over a bundled open dataset (no per-day API limits).
`decode_vin`	$0.002	`{vin}` → 17-char format + North-American check-digit validation and a full NHTSA vPIC decode: make, model, year, body class, engine, plant country. VIN-only (never plate→owner).

Every tool also accepts an optional x_payment (base64 x402 payload) that is forwarded as the X-PAYMENT header to settle the call and return the real result. Humans can instead prepay by card and use an X-FabTally-Key credit key against the HTTP API.
