Zero‑Exposure SMTP Mail Sender (MGC Secure Edition)

A secure SMTP email‑sending MCP server that prevents credential exposure by using MGC Blackbox for local encrypted storage.
Your AI can send emails — but never sees your SMTP password.

✨ Features

  • Zero‑Exposure: SMTP password never leaves your machine
  • Local encryption: Powered by MGC Blackbox secure vault
  • Safe for AI automation: Credentials are never passed to the model
  • Simple API: One MCP tool — send_email
  • Compatible with all SMTP providers

📦 Installation

Install MGC Blackbox:

pip install mgc-blackbox mgc

Clone this skill:

git clone https://github.com/zkeviny/MGC-Blackbox cd MGC-Blackbox/mgc_skill/zero_exposure_smtp_sender

Run the MCP server:

python mcp_server.py

🔐 MGC Blackbox Setup

Create a JSON file containing your SMTP credentials:

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

Store it securely:

mgc_save info_type=config info_owner=your_email < config.json

info_type and info_owner are identifiers you choose when saving credentials.
