SETUP / GET RUNNING

What you'll need

No keys at install. You register a GSTIN and authenticate with an OTP when you start a session.

Pick GST Portal

Select it on the connectors page and build your installer.

Register your GSTIN

Add your GSTIN and authenticate with an OTP. A CA firm can register several.

Fetch and reconcile

Pull GSTR-2A, 2B, and 3B and reconcile them against your books.

Privacy

GST Portal runs on your machine. Credentials live only in your local Claude Desktop config, raw data never reaches our servers, and Claude only ever sees a short, filtered summary. Read how that works.
