How Vinkius protects your data

Can I audit what my AI agents are doing with this integration?

Yes, Vinkius provides an immutable, HMAC-chained audit log. Every tool execution, payload, and response is tracked in real-time on your dashboard, giving you complete visibility into your agent's actions.

How does the AI access my passwords and credentials?

It simply doesn't. On Vinkius, your passwords, API keys, and login details are kept in a secure vault. The AI (like ChatGPT or Claude) merely "asks" Vinkius to perform the task. Vinkius opens the door, does the work, and hands the result back to the AI. Your credentials are never seen, read, or learned by the artificial intelligence.

Does the AI train on my tools or API data?

No. Vinkius enforces a strict Zero-Retention policy. Your data simply passes through our secure servers to complete the requested action and is instantly forgotten. Nothing you do here is ever stored, logged, or used to train any artificial intelligence.

What is an 'Enhanced' address in Mailsac?

An enhanced address is a private inbox that only you can access. Use the reserve_new_address tool to make an address private/enhanced.

What can AI Agents do with Mailsac?

Enable conversational interfaces like ChatGPT and Claude to execute programmatic commands against the Mailsac infrastructure.

ChatGPT disposable email Automation

Use Mailsac to manage disposable email via conversational interfaces. The integration centralizes access control for developer tools operations performed by ChatGPT.

LLM Orchestration for email testing

The Mailsac toolkit provides AI native integration for email testing. It structures data so Claude Code can accurately process developer tools requirements.
