Example Usage

Once connected, just ask your AI naturally:

You

"Check if example.com has proper email security set up"

I'll check the email security configuration for example.com.

tool: email_security({domain: "example.com"})
SPF: v=spf1 -all // found
DMARC: v=DMARC1; p=reject // found
DKIM: no selectors found // not detected
Score: 75/100 (B)

More things you can ask:

▸ "What's the SSL cert expiry for github.com?"

▸ "Scan ports 80, 443, 8080 on my-server.com"

▸ "Has DNS propagated for my-domain.com?"

▸ "What ASN does 1.1.1.1 belong to?"

▸ "Check security headers for my-site.com"

▸ "Traceroute to 8.8.8.8"

▸ "Is 203.0.113.5 on any blacklists?"

▸ "Calculate subnet details for 10.0.0.0/16"
