Zero‑Exposure SMTP Mail Sender (MGC Secure Edition)

Send emails securely without exposing SMTP passwords, powered by MGC Blackbox.

**Overview **

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

bash

pip install mgc-blackbox
mgc

2. Store your SMTP credentials securely

Create a JSON file:

json

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

Store it:

bash

mgc_save info_type=config info_owner=your_email < config.json

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