Resend's first-party MCP — send_email, create_broadcast, manage_audience as MCP tools, with HTML templating Claude can author inline.
Resend MCP exposes the Resend REST API as MCP tools. Claude can compose, preview, and send transactional emails, manage audiences and contacts, and schedule broadcasts. Pair with a humanizer skill for tone control.

claude mcp add resend-mcp -- npx -y @resend/mcp-server一行命令搞定。用 claude mcp list 驗證，claude mcp remove 移除。
