dechonet

DechoNet is a domain-reconnaissance MCP server for AI agents. Point it at a domain or IP and it returns a graded, severity-rated diagnosis with concrete remediation steps — not just raw records. **Start here** - `security_scan` — one-shot audit (DNS, SSL, HTTP, email, ports, propagation, rDNS, ASN) → 0–100 health score with a prioritized action list. **Then drill in** - `dns_lookup` — A/AAAA/MX/TXT/NS/SOA/CAA + DNSSEC and SPF/DMARC syntax checks - `dns_propagation` — one record across 8+ global resolvers (stale vs updated) - `ssl_check` — served certificate, chain, TLS version, HSTS → A+…F grade - `http_security` — CSP/HSTS/X-Frame-Options and redirect-chain audit → grade - `email_auth` — MX, SPF, DKIM (15 selectors), DMARC, BIMI, MTA-STS, DANE - `email_header_analysis` — parse a raw header block: hops, auth results, delays - `port_scan` — common TCP ports, open/closed + service names - `reverse_dns` — PTR + FCrDNS verification - `asn_lookup` — operator, prefixes, cloud/CDN/ISP cla
