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.

"args": [
"-y",
"@resend/mcp-server"

"env": {
"RESEND_API_KEY": "${RESEND_API_KEY}"
}
}
}
}Cursor 使用与 Claude Desktop 相同的 mcpServers 格式。项目级配置优先于全局。

}格式与 Claude Desktop 相同。重启 Windsurf 生效。

"mcpServers": [
{
"name": "resend-mcp",
"command": "npx",
"args": [

"@resend/mcp-server"

}Continue 使用服务器对象数组，而非映射。
{
"context_servers": {
"resend-mcp": {
"command": {
"path": "npx",
"args": [
"-y",
"@resend/mcp-server"
]
}
}
}
}加入 context_servers。Zed 保存后热重载。
claude mcp add resend-mcp -- npx -y @resend/mcp-server一行命令搞定。用 claude mcp list 验证，claude mcp remove 卸载。
何时使用： You drafted release notes and want to send to a single recipient before broadcasting.
结果： Preview email landed in your inbox, ready to broadcast.
何时使用： You have a verified audience and want to send the polished version to everyone.
结果： Broadcast queued in Resend; visible in dashboard.
Pull the release diff, send the notes via Resend
