Developer builds email verification tool using Anthropic's MCP standard

By PulseAugur Editorial · [1 sources] ·

The service, exposed as an HTTP + SSE server, integrates with AI agents like Claude to verify email addresses by checking format, DNS records, SMTP handshake, and disposable domains. The open-source project is monetized through a Stripe payment link for hosted verifications, demonstrating a lean, self-funded approach to building AI agent tools. AI
