Discussion: I built an MCP server with claude code that gives Claude real-time DNS and email security scanning

Saw an interesting discussion on r/ClaudeAI about this — wanted to bring it here. **Original topic:** I built an MCP server with claude code that gives Claude real-time DNS and email security scanning > Hey all — I built an open-source MCP server that lets Claude scan any domain for DNS and email security issues. Built 100% with claude code, running as a cloudflare worker Ask Claude to "scan example.com" and it runs 10 checks: SPF, DMARC, DKIM, DNSSEC, SSL/TLS, CAA, MTA-STS, NS, MX, and subdomain... What are your thoughts? Has anyone here dealt with MCP server? --- *Discuss more at [0n MCP](https://www.0nmcp.com) — the hub for [generative AI tools](https://www.0nmcp.com).*
