⭐ Secure Email Sender (MGC Enhanced)

Secure Email Sender (MGC Enhanced)

Send emails safely without exposing SMTP passwords. Credentials stay encrypted inside your local MGC Blackbox.

⭐ Why this skill?

Most email‑sending tools require you to hardcode SMTP passwords or store them in plaintext.

This skill uses MGC Blackbox, a local encrypted vault:

No hardcoded credentials
No plaintext SMTP passwords
No environment variables
No leaks even if your code is shared

Your AI can send emails — but never sees your password.

🚀 What you can do

Send plain‑text emails via SMTP
Use encrypted credentials stored in MGC
Call from any MCP client (Claude, Cursor, etc.)

🔐 Before you start

1. Install & start MGC Blackbox

pip install mgc-blackbox
mgc

2. Store your SMTP credentials securely

Create a JSON file:

{
  "address": "[email protected]",
  "password": "auth_code",
  "smtp_server": "smtp.email.com",
  "smtp_port": 587
}

Store it:

mgc_save info_type=config info_owner=your_email < config.json

Note: info_type and info_owner are identifiers you choose when saving credentials.

🛠 MCP Tool: `send_email`

Example (Python)

from mcp import MCPClient

client = MCPClient("http://localhost:57219")

client.call_tool("send_email", {
    "to": "[email protected]",
    "subject": "Hello",
    "body": "This is a secure email.",
    "info_type": "config",
    "info_owner": "your_email"
})

💬 Trigger phrases

“send an email”
“send via SMTP”
“email this to someone”

⚠ Limitations

Plain text only
No attachments
No HTML

Recommended Add‑on Sentence

If you need attachments, HTML emails, templates, or automation workflows, you can extend this skill using MGC’s secure local execution capabilities.
