概览

AI 生成的概览

一个远程 MCP 服务器,让助手对钱包、域名、邮件认证、邮箱地址和网址执行预检核查。

可以做什么
它提供六个查询工具:按美国财政部 OFAC 制裁名单筛查加密钱包地址、解析 DNS 记录、评估域名的 SPF、DMARC、DKIM 与 MX 配置、通过 RDAP 查询域名注册时长、在不发信的情况下验证邮箱地址,以及逐跳跟踪网址重定向并给出安全标记。结果以结构化 JSON 返回,包含判定、评分和编码问题。
适用场景
适合助手在采信陌生钱包、域名、邮箱地址或链接之前进行核查,例如检查发件域名的邮件认证、域名注册时长,或短链接最终指向何处。
运行要求
远程 streamable HTTP 端点;未声明软件包、环境变量或请求头。说明中称每次调用通过 x402 收费 0.01 美元,因此需要支持支付的客户端。需要能访问该端点的网络。
安装前请注意
说明称每次调用经 x402 收费 0.01 美元,使用会产生费用并需配置支付。查询内容(钱包地址、域名、邮箱地址、网址)会发送给第三方服务。返回结果仅为参考信号,不构成保证。

ofac_wallet_screen

OFAC SDN Wallet Screen

Screens a crypto wallet address (EVM, BTC, TRON, SOL, XMR and every other chain OFAC lists) against all Digital Currency Addresses on the US Treasury OFAC SDN list. Returns sanctioned true/false, verdict block/no_match, SDN entity name, sdnType, programs and the list publish date. Use when an agent is about to send funds to, pay, or accept funds from an unfamiliar wallet. $0.01 USDC on Base. Paid tool: call it once to get the x402 PaymentRequired object, then retry with params._meta["x402/payment"].

输入参数address必填

dns_lookup

DNS Records Lookup

Resolves live DNS records for any domain or hostname via 1.1.1.1: A, AAAA, CNAME, MX, NS, TXT, SOA and CAA in one call (type=ALL), or a single type incl. SRV, PTR, DS, DNSKEY, HTTPS. Clean JSON with TTLs, NXDOMAIN flag and DNSSEC-authenticated bit. A URL or email address is reduced to its host. Use when an agent needs to verify a domain, find mail servers or nameservers, or read TXT/SPF records. $0.01 USDC on Base. Paid tool: call it once to get the x402 PaymentRequired object, then retry with params._meta["x402/payment"].

输入参数name必填type

email_auth_check

Email Auth Check (SPF/DMARC/DKIM)

Checks a domain's email authentication: parses SPF (+all, ?all, multiple records, over 10 DNS lookups), DMARC (p, sp, pct, rua), DKIM keys (your selector or 15 common ones) and MX, then returns an A-F grade, 0-100 score and coded issues (spf_missing, dmarc_p_none, ...). Use when an agent must judge if a domain can be spoofed, debug deliverability, or vet a sender/vendor domain. $0.01 USDC on Base. Paid tool: call it once to get the x402 PaymentRequired object, then retry with params._meta["x402/payment"].

输入参数domain必填selector

whois_domain_age

Domain Age & Registrar (RDAP)

Looks up a domain in its registry's RDAP server (the ICANN successor to WHOIS, found via the IANA bootstrap): registration date, age in days/years, newlyRegistered (<30 days), expiry, last change, registrar name + IANA ID, EPP status, nameservers and DNSSEC. No personal contact data. Use when an agent must judge if a domain, sender or vendor is brand-new (a phishing/fraud signal). Unsupported TLDs return 400, uncharged. $0.01 USDC. Paid tool: call it once to get the x402 PaymentRequired object, then retry with params._meta["x402/payment"].
