Poland Invoices (KSeF 2.0 national e-invoice API) — questions

Answers built from our own checks of this server.

Is Poland Invoices (KSeF 2.0 national e-invoice API) working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 92 checks got a reply (0.0%), average response time 4 ms. The bar chart above shows every period we have measured.

Is Poland Invoices (KSeF 2.0 national e-invoice API) still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

The registry lists Poland Invoices (KSeF 2.0 national e-invoice API) as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Poland Invoices (KSeF 2.0 national e-invoice API)?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Poland Invoices (KSeF 2.0 national e-invoice API) need an API key?

No. Poland Invoices (KSeF 2.0 national e-invoice API) completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. This is what we observed, not what the docs claim.
