Domain and email trust checks for AI agents: DNS, MX, SPF/DMARC, domain age, disposable and role addresses. Free MCP tools; paid calls use x402 USDC on Base. Built by Crypto Money Maker. https://youraitools.co/guides

The two tools target clearly different resource types: domains versus email addresses. An agent can easily select the right tool based on whether it is checking a link/sender domain or a specific email address.
Both tools follow the same predictable verb_noun convention: check_domain and check_email. The naming is fully consistent and self-explanatory.
Two tools is on the thin side for a domain/email verification server, especially since each tool bundles several checks. However, the two tools map cleanly to the two core resource types and neither is redundant.
Each tool covers a useful subset of checks, but important capabilities like domain registration age, risk score, MX verification, and an overall email verdict are explicitly deferred to paid x402 endpoints. This leaves notable gaps for agents that need a complete trust decision from the MCP surface alone.
Check a domain before your agent trusts a link, a sender or a counterparty: does it exist, where does its mail go, SPF and DMARC policy, nameservers, DNSSEC. Free tier (preview). For registration age, registrar, parking detection and a 0-100 risk score use the paid x402 endpoint /v1/domain.
Inputs: domain (required).
Check an email address an agent is about to store, email or trust: syntax, disposable / throwaway provider, role account, free webmail. Free tier (no network). For MX, mail auth, domain age and a verdict (valid | risky | undeliverable) use the paid x402 endpoint /v1/email.
Inputs: email (required).
