Capabilities

Tools

6 tools
dns_lookup
Look up DNS records for a domain via Cloudflare DNS-over-HTTPS. Returns A, AAAA, MX, NS, TXT, CNAME, and SOA records. Use to see where a domain is hosted, who runs its mail and DNS, and what verification/policy TXT records it publishes.
Input schema 
{'type': 'object', 'required': ['domain'], 'properties': {'types': {'type': 'array', 'items': {'type': 'string'}, 'description': 'Optional subset of record types, e.g. ["MX","TXT"]. Defaults to all common types.'}, 'domain': {'type': 'string', 'description': 'Domain name, e.g. stripe.com'}}}
domain_intel
Registration intelligence for a domain via RDAP (the modern WHOIS). Returns registrar, creation/expiration/last-changed dates, domain age in years, EPP status codes, nameservers, DNSSEC state, and abuse contact. Use to vet a company, assess a lead, or judge how established a domain is.
Input schema 
{'type': 'object', 'required': ['domain'], 'properties': {'domain': {'type': 'string', 'description': 'Domain name, e.g. stripe.com (no scheme)'}}}
domain_report
One-call full dossier on a domain: registration (RDAP), DNS records, email deliverability, and website tech stack, combined into a single report. Use for fast lead qualification, company research, or recon without four separate calls.
Input schema 
{'type': 'object', 'required': ['domain'], 'properties': {'domain': {'type': 'string', 'description': 'Domain name, e.g. stripe.com'}}}
email_deliverability
Assess whether a domain (or the domain of an email address) can receive mail and how strong its sender authentication is. Returns MX presence, SPF and DMARC policy, whether it's a free consumer provider (gmail, etc.) or a known disposable/temp-mail provider, and an overall verdict. Use to qualify leads and flag throwaway signups.
Input schema 
{'type': 'object', 'required': ['domain_or_email'], 'properties': {'domain_or_email': {'type': 'string', 'description': 'A domain (stripe.com) or an email address (a@stripe.com)'}}}
subdomains
Discover subdomains of a domain from public Certificate Transparency logs (crt.sh). Useful for mapping a company's public surface (app., api., staging., etc.). Best-effort: crt.sh can be slow; returns a note if unavailable.
Input schema 
{'type': 'object', 'required': ['domain'], 'properties': {'domain': {'type': 'string', 'description': 'Registrable domain, e.g. stripe.com'}}}
tech_stack
Fingerprint the technology behind a website by fetching its homepage. Detects web server, CMS/framework (WordPress, Shopify, Next.js, etc.), CDN, analytics, and returns the page title, final URL after redirects, and key response headers. Use for competitive research and lead enrichment.
Input schema 
{'type': 'object', 'required': ['domain'], 'properties': {'domain': {'type': 'string', 'description': 'Domain or full URL, e.g. shopify.com'}}}
