对于销售和潜在客户开发团队：在发送外联前，对每封潜在客户邮件都取得保留、修复、审核或放弃的决定。

1.Connect（免费，无需密钥;可在Claude Desktop、Cursor、Cline、VS Code及任何支持远程可流媒体HTTP的客户端中运行）：

2.问： “[email protected] 可以发邮件吗？” 你的经纪人来电：

3.Get（免费演示端点的真实输出，已裁剪）：

有什么不同

• 决策，而非原始标志：大多数邮件验证者返回15个布尔，让代理自行猜测。这返回了该做什么。
• 拼写错误已修复，而非仅标记：[email protected] 返回为 fix -> [email protected]。
• 一个准备发送列表：score_batch 返回 send_list]，即已保留地址的去重列表及修正地址，以及保留/修复/复查/丢弃计数。
• B2B意识：职位收件箱（info@、sales@）和免费邮箱会发送到review，原因是它们只到达公司，但很少送到决策者手中。
• 不会发送邮件（没有可能导致IP被屏蔽的SMTP探测），且它是MCP原生，配备免费无密钥演示端点。

无代码版本

不搭建代理？同样的评分也存在于现成工具中：

B2B Email & Domain Scorer — remote MCP server

For sales and lead-gen teams: get a keep, fix, review or drop decision for every lead email before you send outreach.

1. Connect (free, no key; works in Claude Desktop, Cursor, Cline, VS Code and any client that supports remote Streamable HTTP):

{
  "mcpServers": {
    "email-scorer": {
      "url": "https://email-scorer.mohamed-bahaa53000.workers.dev/demo/mcp"
    }
  }
}

2. Ask: “Is [email protected] OK to email?” Your agent calls:

{"name":"score_email","arguments":{"email":"[email protected]"}}

3. Get (real output from the free demo endpoint, trimmed):

{"action":"fix","send_to":"[email protected]",
 "action_reason":"Likely typo: send to [email protected] instead",
 "verdict":"risky","score":10,"reasons":["likely_typo","typo_domain_is_disposable_or_parked"]}

What makes it different

• Decisions, not raw flags: most email validators return 15 booleans and leave your agent to guess. This returns what to do.
• Typos fixed, not just flagged: [email protected] comes back as fix -> [email protected].
• A ready-to-send list: score_batch returns send_list, the deduplicated list of kept plus corrected addresses, and keep/fix/review/drop counts.
• B2B-aware: role inboxes (info@, sales@) and free mailboxes go to review with the reason, because they reach a company but rarely a decision-maker.
• No mail is sent (no SMTP probing that can get your IP blocklisted), and it’s MCP-native with a free, keyless demo endpoint.

No-code version

Not building an agent? The same scoring comes in ready-made tools:

• Free email list cleaner checks and cleans up to 25 emails in your browser, with no sign-up.
• Free n8n template: Lead Scoring & Routing scores form leads with Gemini, logs them to Sheets and alerts Slack.

Try it free

• No key, right now: point any MCP client at https://email-scorer.mohamed-bahaa53000.workers.dev/demo/mcp (10 tool calls per IP per day).
• Free RapidAPI plan: 100 requests/month on the Basic plan, no card needed. Pro is $3.99 for 30,000.

This is a hosted (remote) MCP server using Streamable HTTP. There is nothing to install or run locally, and this repository holds documentation and the MCP Registry manifest only. The server code is not open source.
