How Vinkius protects your data

Can I set different limits for each virtual assistant on my team?

Absolutely. You have full control in our command center. You can create an AI agent that only "reads" data so the support team can answer questions, and another superpowered agent that can "edit" and "create" information exclusively for your operations team. Each AI gets exactly the level of access you allow.

Can I download the authorized XML?

Yes, use the download_xml tool with the document reference to retrieve the full XML content.

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.

What happens if the underlying API rate limits my agent?

Our edge infrastructure automatically handles backoffs, queueing, and throttling. If an AI agent sends too many erratic requests, Vinkius manages the rate limits gracefully, ensuring your backend doesn't crash.

What can AI Agents do with Focus NFe?

Build automated workflows with Cursor and Claude Code by connecting to the Focus NFe MCP server.

Optimizing fiscal invoicing with Claude

Use the Focus NFe server to execute fiscal invoicing operations from your AI agent. The protocol manages state and authentication for continuous erp operations workflows.

The Future of tax compliance

The Focus NFe connection gives ChatGPT direct access to tax compliance tools. The integration handles the logic required for continuous erp operations operations.
