# Resend MCP Server Extension for Zed

This extension provides a MCP server for sending emails via [Resend](https://resend.com) directly from [Zed](https://zed.dev).
It uses the (unofficial) [resend-mcp](https://www.npmjs.com/package/resend-mcp) npm package.

## Configuration

### Minimal Configuration (API Key Only)

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

```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](https://resend.com/domains).

```json
{
  "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:

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

```
