FAQ

Can a WorkAist AI agent really automate KSeF (Krajowy System e-Faktur) end-to-end?

Yes. The connector exposes read and write tools through Model Context Protocol. AI agents call them through plain-language instructions in a CLAUDE.md file — no glue code.

How does this differ from using the KSeF (Krajowy System e-Faktur) API directly?

The connector adds permission isolation, audit logging, cost tracking per agent, and reversible PII redaction at the LLM boundary. It also presents KSeF (Krajowy System e-Faktur) as part of a unified Knowledge Graph alongside your other tools.

What does it cost?

WorkAist is open-source under AGPL-3.0 and self-hosted, so the connector itself is free. You pay only for KSeF (Krajowy System e-Faktur)'s own API costs (if any) and the LLM tokens your agent consumes.

Is my KSeF (Krajowy System e-Faktur) data sent to a third party?

No. WorkAist runs in your own infrastructure. Data flows from KSeF (Krajowy System e-Faktur) → your WorkAist instance → the LLM you choose. Sensitive fields can be tokenized before reaching the LLM.

What if KSeF (Krajowy System e-Faktur) changes its API?

The connector is versioned and published openly. When KSeF (Krajowy System e-Faktur) ships breaking changes, we bump the connector version and the marketplace UI surfaces the upgrade as a one-click apply.
