远程 MCP 服务器,对域名进行公开的邮件安全评估(SPF、DMARC、DKIM、MTA-STS、DNSSEC、DANE、TLS-RPT)并返回评分结果。
Web executable,通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。
把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体,或 SourceWeft 对话中。智能体会读取该服务器的安装指南,先向你展示发布者、端点和登录方式,经你同意后再把它添加到你的客户端。密钥不会写进任何命令。
阅读 https://sourceweft.com/mcp/one.seclens%2Fseclens/install.md,并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前,先告诉我它的发布者、端点和登录方式,等我确认。不要把 API 密钥写进命令或我会提交的文件;问我密钥应从哪里获取。把它添加到你客户端的 mcpServers 配置中。

}Standalone Go CLI for the public email-security checks on SecLens.ONE.
Scored protocols are SPF, DMARC, DKIM, MTA-STS, TLS-RPT, DANE, and DNSSEC. BIMI is informational and does not change the score. The assessor uses passive DNS and one HTTPS GET to the MTA-STS policy endpoint. It does not send mail.
Protocol logic lives in internal/assessor/rfc*/ packages. Thin bridge files wire DNS lookups and scoring.

_smtp._tls advertisement and reporting URIs.Bulk assessment uses bounded concurrency. Output is text, JSON, or JSONL. JSON DoH resolvers default to Cloudflare. Google and Quad9 are supported.
Anonymous Streamable HTTP at https://seclens.one/mcp.
Tools are get_result, assess_domain, and get_summary.

mcp.json:
Core DNS and HTTP use the Go standard library. One module dependency handles internationalized domain names.
golang.org/x/net/idna handles punycode and IDNA for MTA-STS MX host matching.Run go list -m all after go mod download to inspect the module graph.
Resolver flag values are cloudflare, google, and quad9. Separate a pool with commas.
The CLI measures the same controls as the SecLens Top-1M studies:
