/ how

Three steps. That's it.

No proxy server, no middleware, no custom integration. One URL, one key, it works.

Add your credentials

NAV technical user, Billingo API key, MiniCRM access. Everything AES-256-GCM encrypted, stored server-side.

Copy your MCP URL

A unique endpoint that Claude Desktop, Cursor, or any MCP-compatible client can plug into.

Talk in plain language

"List last month's incoming invoices from NAV" — and it works. The connector translates to API calls.

/ architecture

How does it actually work?

MCP is an open protocol. connectors.hu is a secure proxy that translates AI instructions into API calls — using your own keys.
