MCP tools · 1 exposed · ~325 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
lookup_domain_whois ~325

Look up who registered a domain, when, and when it expires. Give domains, website URLs, or email addresses (up to 5,000). For each registrable domain the actor asks the registry's own RDAP server (from the IANA list), or its port 43 WHOIS server where there is no RDAP, and returns one row: registered true or false, registrar, created_at, updated_at, expires_at, domain_age_days, days_until_expiry, status codes, nameservers, dnssec, and the registrant organization and country where the registry publishes them. Rows with no dates published, error rows, and input that is not a domain come back free with a row_status saying so. A run that does not succeed is returned as an error with its run ID. Read-only; requires an APIFY_TOKEN; Apify charges per domain lookup.

NameTypeReqDescription
domainstring–One domain, URL, or email address, for example stripe.com.
domainsarray–Domains, website URLs, or email addresses, up to 5,000. Subdomains are looked up as their registrable domain.
follow_registrar_rdapstring–true (default) also reads the registrar's RDAP record for the abuse email and any registrant details it publishes.
include_rawstring–true puts the registry's raw RDAP JSON or WHOIS text in raw_response. Default false.
max_charge_usdstring–Optional. The run stops before a charge would pass this amount.
