How this service works
Inspects live IPv4/IPv6 DNS resolution, TLS certificate issuer/expiry, and HTTP security grade. (Live x402 v2, IETF MPP & MCP endpoint at https://mcp-compiler.agentdiet.dev/v1/tls-scanner)
Output
Returns live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate details (issuer, validity dates, expiry), and an HTTP security header assessment or grade for the queried domain.
Example use cases
Pre-deployment security audit
“Before we go live, can you check the TLS certificate and HTTP security headers for myapp.example.com and tell me if anything looks risky or misconfigured?”
Vendor due diligence OSINT
“I need to vet a new vendor — can you pull the DNS records, TLS cert issuer and expiry, and security header grade for vendorcompany.io so I can assess their infrastructure hygiene?”
Certificate expiry monitoring check
“Our SSL certificate for api.acmecorp.com might be expiring soon — can you check who issued it and exactly when it expires so I know if we need to renew urgently?”
Technical details
Endpoint
GEThttps://mcp-compiler.agentdiet.dev/v1/tls-scanner?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined, single-call OSINT snapshot covering DNS, TLS, and HTTP security headers for a domain — especially useful for security audits, vendor assessments, certificate expiry checks, or infrastructure reconnaissance, without needing to run separate dig/nmap/SSL Labs queries.
Side effects
- Domain does not exist or fails DNS resolution — returns error or empty DNS records
- Domain has no TLS certificate (HTTP-only) — TLS fields absent or null
- Network timeout reaching the target domain — returns timeout or connection error
- Malformed domain input — returns validation error
- Domain blocks scanning or returns misleading headers — results may be incomplete
