概览

AI 生成的概览

远程 MCP 服务器,用于邮件送达率:审计发信域名的 SPF、DKIM、DMARC、MX 与 TLS,监控变更并检查邮箱地址。

可以做什么
  • 审计发信域名:MX、展开 include 并统计查询次数的 SPF、DMARC 策略、DKIM、MTA-STS、TLS-RPT 与 BIMI,并给出评级和修复建议
  • 对比多次审计结果,并注册域名由服务器每日检查,变更以 JSON POST 到 webhook
  • 将超过 10 次查询上限的 SPF 记录扁平化,返回需要发布的 TXT 记录
  • 获取修复套件,按邮件服务商给出应发布的具体 DNS 记录
  • 检查邮箱地址的语法、域名是否收信、拼写建议以及一次性或共享邮箱标记
  • 查询域名注册信息(RDAP)、TLS 证书状态和 SpamCop/PSBL 黑名单,并根据原始邮件头解释认证结果
适用场景
适合管理发信域名时,让助手诊断邮件为何进入垃圾箱、核对 SPF/DKIM/DMARC 配置,或持续关注 DNS 变更。也适合在信任某个发件方之前快速查看域名年龄、证书和黑名单情况。
运行要求
远程 Streamable HTTP 端点,连接无需密钥。免费工具每次调用最多审计 3 个域名。付费功能通过 Base 主网的 USDC x402 支付,或使用通过开通接口获得的带额度 API 密钥。
安装前请注意
部分工具需要付费:verify_email 每次消耗 1 个额度或 0.01 USDC,修复套件、额度包和 guard pass 均以 Base 上的 USDC 支付,涉及钱包交易。watch_sending_domains 会把域名变更数据发送到你提供的 webhook 地址。地址检查仅到域名层面,无法确认具体收件箱是否存在。

README

VerifyPulse MCP Server & Agent Client

Public Model Context Protocol (MCP) server card and client interface for VerifyPulse (https://verifypulse-seven.vercel.app), which checks whether email will arrive: daily sending-domain monitoring, on-demand DNS audits and domain-level address checks, paid in USDC on Base over x402.


What VerifyPulse does

  • Sending-domain audits: MX, SPF with every include expanded and the true lookup count, DMARC policy and DKIM keys
  • Daily monitoring: signed webhook alerts when a domain's SPF, DKIM, DMARC, MX or MTA-STS changes
  • Bulk-sender checks: a domain's DNS against the Gmail and Yahoo SPF, DKIM and DMARC requirements
  • Domain age and TLS checks: RDAP registration data and certificate status
  • Address checks: RFC 5322 syntax, the domain's MX records, typos, and disposable and shared-mailbox flags

What it does not do

Address checks are domain-level. VerifyPulse does not offer mailbox verification and cannot confirm that a specific inbox exists. GET /v1/x402/verify-email runs no SMTP probe and reports smtp_check: not_performed. The MCP verify_email tool may attempt one, but the hosting platform commonly filters outbound port 25, so a mailbox result cannot be promised.


Remote MCP server (Streamable HTTP)

Connect any MCP client that supports remote servers:

json
{  "mcpServers": {    "verifypulse": {      "type": "http",      "url": "https://verifypulse-seven.vercel.app/mcp"    }  }}
  • Endpoint: POST https://verifypulse-seven.vercel.app/mcp
  • Protocol: JSON-RPC 2.0 (Model Context Protocol), no key needed to connect

x402 payments on Base Mainnet

  • Network: Base Mainnet (eip155:8453)
  • Token: USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913)
  • Recipient: 0x42871B99A3AA942D3B8EC7E43D37979886E856cA
  • Facilitators: https://facilitator.xpay.sh, then https://facilitator.payai.network (POST /settle)
  • Direct: a recent Base USDC transfer hash to the recipient in X-PAYMENT or X-Payment-TxHash, redeemable once

Quick start (Python)

Sending-domain audits are free for up to 3 domains per call, with no key:

python
import jsonimport urllib.request
req = urllib.request.Request(    "https://verifypulse-seven.vercel.app/v1/guard/audit",    data=json.dumps({"domains": ["github.com"]}).encode(),    headers={"Content-Type": "application/json"},)with urllib.request.urlopen(req) as resp:    print(json.loads(resp.read().decode()))

工具

12

inspect_domain_dns

Free. Audit one sending domain: MX hosts, SPF with every include expanded and the true DNS lookup count against the limit of 10, DMARC policy including inheritance from the parent domain, and published DKIM keys. Returns a grade and the fixes to make.

输入参数domain必填

audit_sending_domains

Free for up to 3 domains per call. Audit several sending domains at once and get a grade, SPF lookup count, DMARC policy, DKIM status, MTA-STS (policy checked against the MX hosts), TLS-RPT, BIMI and fixes for each, plus a snapshot to pass to monitor_sending_domains later.

输入参数domains必填

monitor_sending_domains

Free for up to 3 domains per call. Report what changed in SPF, DKIM, DMARC, MX, MTA-STS, TLS-RPT and BIMI since a previous run. Pass the `snapshots` object returned by the previous call as `previous`; the server stores nothing. The first call returns a baseline with no changes.

输入参数domains必填previous

watch_sending_domains

Hosted monitoring. Register domains for a daily server-side check of SPF, DKIM, DMARC, MX, MTA-STS, TLS-RPT and BIMI; when something changes, the changes are POSTed as JSON to your https webhook_url. Free for up to 3 domains (renew every 30 days). For 4 to 20 domains in one watch, call without a pass: the result is an x402 payment request for the pass that covers them ($5 for up to 50 domains), payable in params._meta["x402/payment"] or with api_key credits; the paid call returns the pass and starts the watch. Returns a token to list or delete the watch.

输入参数api_keydomains必填guard_passwebhook_url必填

flatten_spf

Free. Replace the includes in a domain's SPF record with the IP ranges they resolve to, and return the TXT records to publish. Use it when an SPF record is at or over the 10-lookup limit.

输入参数domain必填

get_fix_kit

Fix a domain whose email goes to spam or fails SPF, DKIM or DMARC. Returns the exact DNS records to publish (host, type, value) for its mail provider, built from live DNS, in order, with the reason for each. Called without payment it returns a free preview of the fixes plus an x402 payment request for $0.25 USDC on Base (or 250 credits with api_key); a domain that needs no new records gets its advice free.

输入参数domain必填api_key

verify_email

Check an email address: syntax, whether its domain accepts mail, typo suggestion, disposable and shared-mailbox flags. Checks the domain, not the individual inbox. Costs one credit with an API key (POST /v1/agent/provision returns a key with 100 free credits), or $0.01 USDC on Base per call over x402.

输入参数email必填api_key

domain_intel

Free. Registration data for one domain from the registry (RDAP): when it was registered and its age in days, expiry, registrar, status codes, nameservers and DNSSEC. Flags domains registered in the last 30 days, a strong spam and fraud signal, and domains about to expire.

输入参数domain必填

check_tls_certificate

Free. The TLS certificate a host serves on port 443: whether it validates, issuer, names covered, expiry and days left.

输入参数host必填

check_blocklists

Free. Whether an IPv4 address, or a domain's MX and A addresses, are listed on the SpamCop and PSBL blocklists. Spamhaus and Barracuda are not queried (their terms require a subscription); the result says which lists were checked.

输入参数target必填

analyze_email_authentication

Free. Explain why an email passed or failed authentication or went to spam. Pass the raw message, or just its headers: checks DKIM signatures (verified when the body is included), whether the sending IP is authorized by SPF, DMARC alignment and policy, what the receiving server recorded, and delays at each relay hop. Returns the reasons in plain words.

输入参数raw必填

get_x402_payment_endpoints

List the paid HTTP endpoints, their prices in USDC on Base, and the free endpoints.

无需输入参数。
