  "instructions": "DechoNet domain-reconnaissance tools (free, no API key). Recommended workflow: 1) security_scan for the overall verdict, then the specific tool for each flagged area (dns_lookup, ssl_check, http_security, email_auth, subdomain_discovery, lookalike_domains, owasp_check, impersonation_exposure). 2) When the user cares about this domain going forward, call watch_domain once — DechoNet then re-checks it daily and records every change. 3) On a later session about the same domain, start with domain_changes: it reports what changed since the last lookup or watch check (grade drops, new issues, cert renewals, DNS drift) — something a fresh one-off lookup cannot tell you. Every result is interpreted (status, key numbers, issues with severity and confidence, concrete actions) and ends with a link to the full interactive report you can hand to the user. All tools except watch_domain are read-only. Setup guide for humans: https://dechonet.com/mcp",
