Resend MCP Server Extension for Zed

This extension provides a MCP server for sending emails via Resend directly from Zed. It uses the (unofficial) resend-mcp npm package.

Configuration

Minimal Configuration (API Key Only)

Add your Resend API key to your Zed settings.json:

{
  "context_servers": {
    "mcp-server-resend": {
      "settings": {
        "resend_api_key": "re_your_actual_api_key_here"
      }
    }
  }
}

Recommended Configuration (With Sender Email)

Ensure your sender email is from a verified domain. You can do that by going to Resend's dashboard Domain page.

{
  "context_servers": {
    "mcp-server-resend": {
      "settings": {
        "resend_api_key": "re_your_actual_api_key_here",
        "sender_email_address": "your-verified@yourdomain.com"
      }
    }
  }
}

Complete Configuration (All Options)

You can also configure reply-to addresses:

{
  "context_servers": {
    "mcp-server-resend": {
      "settings": {
        "resend_api_key": "re_your_actual_api_key_here",
        "sender_email_address": "your-verified@yourdomain.com",
