Email Validator

lazymac2x/email-validator-api

Validates email addresses through a remote Cloudflare Workers API, exposing four MCP tools: single validation, batch validation (up to 100 emails), domain checks, and typo suggestions. Each validation returns syntax compliance (RFC 5322), MX record status, disposable/role-based detection, SPF/DKIM checks, and a 0-100 risk score. Reach for this when you need Claude to verify user input, clean email lists, or catch common typos like "gmial.com" before sending. The server runs on streamable-http transport at api.lazy-mac.com. Part of the lazymac ecosystem that bundles 42+ developer tools, though this standalone server focuses purely on email validation workflows.
