Ask, don’t search
Ask questions. Get real data.
Instead of searching different databases and APIs, simply ask your AI agent. It selects the right MarketXY tools, searches the data, and gives you one useful answer.
“Give me everything you know about example.com.”
“Who owns this domain?”
“Show me the WHOIS history.”
“What company operates this website?”
“Find business emails for this company.”
“Find people connected with this company.”
“Find all domains connected with this email.”
“Show me every domain using this IP.”
“Find subdomains and SSL certificates.”
“Check if this domain has security risks.”
What is MarketXY MCP?
MarketXY MCP is a Model Context Protocol server that connects AI applications directly with MarketXY data. It gives AI agents structured access to domain, WHOIS, company, contact, network, DNS, technology, and cybersecurity intelligence.
Instead of building many API integrations, you connect one MCP server — your AI agent then searches whichever dataset it needs, automatically.
Beyond registration lookups
More than a WHOIS MCP
Traditional WHOIS tells you about a domain registration. MarketXY MCP goes much further — a single domain can be connected with:
WHOIS recordsHistorical WHOISRegistrantsCompaniesPeopleBusiness emailsPhone numbersAddressesSocial profilesIP addressesASNHostingDNS recordsNameserversMX serversTXT recordsSSL certificatesSubdomainsTechnologiesCMSWeb serversDomain categoriesCountry signalsRelated domainsBlacklist signalsCybersecurity data
Your AI agent can connect these signals to build a much bigger picture.
Every dataset, one connection
What your AI agent can research
WHOIS Intelligence
Access current and historical WHOIS information.
Current WHOISLive WHOISParsed WHOISRaw WHOISHistorical WHOISWHOIS timelineDomain ownershipRegistrantRegistrarRegistration dateExpiration dateUpdated dateDomain ageDomain statusPrivacy detectionContact informationOwnership changesRegistrar changesEmail historyPhone historyCompany historyNameserver historyCountry history
“Show me how the ownership of example.com changed over time.”
Reverse WHOIS
Start with information about a person or company and discover connected domains.
EmailPhonePerson nameCompanyOrganizationAddressKeywordNameserverDNS information
“Find domains connected with [email protected].”
“Find domains registered to Example Technologies Ltd.”
Reverse searches can help discover relationships that are difficult to find with a normal domain lookup.
Company Intelligence
Turn a domain into company information.
Company nameWebsiteBusiness descriptionIndustryBusiness categoryCountryLocationCompany sizeContact informationBusiness emailsPhone numbersPeopleSocial profilesRelated websitesTechnologiesInternet infrastructure
“Research the company behind example.com.”
Email Intelligence
Search available email intelligence connected with domains, people, and companies.
Domain → EmailsCompany → EmailsPerson → EmailEmail → DomainEmail → CompanyEmail → Related domains
“Find available business emails for this company.”
The AI can combine email information with company and domain intelligence to provide better context.
People Intelligence
Discover available people connected with companies and websites.

“Find people working in cybersecurity at this company.”
Phone Intelligence
Search phone information connected with domains and businesses.
Domain → PhoneCompany → PhonePhone → DomainsPhone → CompanyHistorical WHOIS phone numbers
“What domains have been connected with this phone number?”
DNS Intelligence
Give your AI access to DNS infrastructure.

“Show me the DNS infrastructure behind example.com.”
IP Intelligence
Investigate IPv4 and IPv6 infrastructure.
IP addressReverse IPDomains on an IPASNNetworkHosting providerCountryRelated infrastructureConnected websites
“Find domains hosted on the same IP as example.com.”
SSL Intelligence
Research SSL certificates and certificate relationships.
SSL issuerSSL subjectValid fromExpirationCertificate statusSubject countryCertificate domainsRelated domainsCertificate relationships
“Find other domains connected with this SSL certificate.”
Subdomain Intelligence
Discover known subdomains.
“Find all known subdomains for example.com.”
Your AI can combine subdomain information with IP, SSL, DNS, and technology data for deeper infrastructure research.
Technology Intelligence
Understand what technologies a website uses.
CMSWeb serverHostingWebsite technologiesEmail providerDNS providerSSL infrastructureOther detected technologies
“Which companies use WordPress and Cloudflare?”
Newly Registered Domains
Access newly registered domain intelligence through your AI agent.
DateTLDKeywordCountryRegistrarCompanyAvailable WHOIS informationOther domain signals
“Find newly registered .com domains containing the word "security".”
The AI can then enrich these domains with other available MarketXY data.
Cybersecurity & Threat Intelligence
Use MarketXY MCP for domain and infrastructure investigations.

“Investigate suspicious-example.com and give me a security report.”
The AI can automatically use several tools and combine the results.
Sales & Company Research
Research businesses before contacting them.

“Research example.com as a possible customer.”
This can help sales and research teams understand a company before contacting it.
Domain enrichment
A domain can be the starting point for a much larger investigation. Ask “Enrich example.com” and the AI searches multiple sources, ending in one combined domain intelligence profile.

Company enrichment
You can also start with a company. Ask for “a complete intelligence profile for Example Inc.” and the AI works outward from there — useful for far more than domain research.

One question can trigger many searches
Ask “Investigate example.com” and your AI agent could, in order:
- 1Look up current WHOIS.
- 2Check historical WHOIS.
- 3Find ownership changes.
- 4Identify the company.
- 5Find available people.
- 6Find available business emails.
- 7Find phone numbers.
- 8Check IP and ASN.
- 9Find DNS records.
- 10Find nameservers and MX servers.
- 11Check SSL certificates.
- 12Discover subdomains.
- 13Detect website technologies.
- 14Check blacklist and risk signals.
- 15Find related domains.
- 16Create one combined report.
You do not need to call every tool yourself — the AI agent decides which ones it needs.
Search from any signal
Start your investigation with almost any piece of information — useful for relationship discovery and internet intelligence.
