myDATA MCP Connector

Your tax data from AADE, one question away: transmissions, income, expenses, VAT.

Request a demo Create account

The connector talks to the official myDATA REST API and brings into Claude whatever has already been transmitted for your business. It is strictly read-only: submission and cancellation calls were never implemented, so nothing can ever be sent to the tax authority through AI.

What you can do

Issued documents

Everything you have transmitted, by period, type or counterparty, with MARK.

Received documents

What suppliers transmitted to you — the basis for expense checks.

Income & expense summaries

Fast period totals without pulling every single document.

VAT data

VAT picture per period, so you know what's coming before your accountant calls.

Reconciliation with the ERP

Compare what the ERP says with what reached AADE and find discrepancies.

Example questions

Use them as they are — or in your own words.

›What did I transmit to myDATA this quarter?
›Which documents did suppliers send me last month?
›What income and expenses do my books show for the half-year?
›Do the ERP sales match what I have transmitted?
›Show me type 1.1 documents for July.
›What's my VAT position for the quarter?

Frequently asked

Can it submit a document to AADE?+

No, in no way. Submission and cancellation calls do not exist in the code and the client blocks anything that is not a read operation.

What do I need to connect?+

A User ID and Subscription Key from your myDATA REST API registration with AADE. Both the test and production environments are supported.

Does it work if I use another ERP?+

Yes — myDATA is independent of your ERP. One connector covers any business, whatever software it runs.
