Email Send API

br0ski777/email-send-x402

Provides programmatic email sending through the Resend API, supporting both plain text and HTML content. Built on the x402 micropayment protocol, meaning you'll pay per send rather than managing monthly API quotas. The server exposes its MCP interface over SSE at a hosted endpoint, so there's no local setup required. Reach for this when you need Claude to send transactional emails, notifications, or reports without leaving the conversation. The x402 integration handles payment routing automatically, though you'll want to verify pricing before high-volume use since the repository doesn't include rate documentation.
