概覽

AI 產生的概覽

一個遠端 MCP 伺服器,讓助理對錢包、網域、郵件驗證、電子郵件地址和網址執行預檢核查。

可以做什麼
它提供六個查詢工具:依美國財政部 OFAC 制裁名單篩查加密錢包地址、解析 DNS 記錄、評估網域的 SPF、DMARC、DKIM 與 MX 設定、透過 RDAP 查詢網域註冊時間、在不寄信的情況下驗證電子郵件地址,以及逐跳追蹤網址重新導向並提供安全標記。結果以結構化 JSON 回傳,包含判定、評分和編碼問題。
適用情境
適合助理在採信陌生錢包、網域、電子郵件地址或連結之前進行核查,例如檢查寄件網域的郵件驗證、網域註冊時間,或短網址最終導向何處。
執行需求
遠端 streamable HTTP 端點;未宣告套件、環境變數或標頭。說明指出每次呼叫透過 x402 收費 0.01 美元,因此需要支援付款的用戶端。需要能連線至該端點的網路。
安裝前請注意
說明指出每次呼叫經 x402 收費 0.01 美元,使用會產生費用並需設定付款。查詢內容(錢包地址、網域、電子郵件地址、網址)會傳送給第三方服務。回傳結果僅為參考訊號,不構成保證。

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"].

輸入參數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"].

輸入參數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"].

輸入參數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"].

輸入參數domain必填

Email Address Verify (MX, no SMTP)

Checks an email address without sending mail or opening SMTP: syntax, domain exists, MX records (or RFC 5321 A/AAAA fallback), RFC 7505 null MX, MX host resolves, disposable-domain list (~9.9k domains), role account (info@, support@) and free provider. Verdict deliverable_domain, risky, undeliverable or unknown. Cannot prove the mailbox itself exists. Use when an agent validates a signup, lead or contact email before using it. $0.01 USDC.
