概览

AI 生成的概览

一个托管验证套件，让助手按次付费校验欧盟增值税号、IBAN、邮箱地址、地名和车辆识别码。

可以做什么: 校验欧盟/欧洲经济区增值税号，做格式与校验和预检并实时查询 VIES，返回注册状态及可得的公司信息。离线校验 IBAN 的长度、mod-97 校验和、国家与银行标识。检查邮箱地址的语法、实时 MX 记录、一次性域名和角色地址。将地名或国家/州/城市输入解析为规范名称、ISO 代码、层级、人口和坐标。解码 VIN，做校验位验证并通过 NHTSA vPIC 完整解析品牌、车型、年份和发动机。
适用场景: 适合助手需要快速、权威地校验增值税号、IBAN、邮箱、地点或车辆 VIN 等业务标识时，例如清理客户或供应商记录、检查表单输入。
运行要求: 远程 streamable-HTTP 端点 valid.fabtally.com，或通过 npx 运行本地 npm 包 fabtally-valid-mcp。无需账号或 API 密钥，但每次工具调用都需通过 x402 以 Base 上的 USDC 付费；未付费的调用会返回支付挑战。可用 FABTALLY_VALID_BASE 设置可选的基础地址。

安装前请注意

每次调用都收费，通过 x402 支付载荷以 Base 上的 USDC 结算，助手可能在用户未明确要求时产生支出。增值税查询会把号码发送给官方 VIES 服务，邮箱检查会把域名发送给 DNS，VIN 解码会发送到 NHTSA vPIC API。结果不构成法律、税务或财务建议。

安装

在 SourceWeft 中

打开控制台中的 FabTally Valid，将其添加到工作区。
为需要使用其工具的对话启用该服务。

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.

Validate an EU/EEA VAT number: give {country_code, vat_number} and get a per-country format + checksum pre-check AND a LIVE lookup against the official VIES service — returning valid/registered plus the registered company name & address when VIES provides them (cached ~1h to shield the flaky VIES). Without payment returns the x402 challenge; pass x_payment to settle.
