## FAQ

### Do I need a digital certificate (A1/A3) in the client?

No, the certificate is uploaded once at app.stackin.io and remains on the server side.

### Does it work in production, or only homologation?

It works in both environments, which are determined by your API key or authorized OAuth connection.

### Is the service free?

Issuing invoices uses credits from your Stackin account, but consulting and cancelling documents do not.

### Can I use the server without the plugin?

Yes, it is a standard MCP server; the plugin simply provides skills and simplifies configuration.
