FAQ

Can a WorkAist AI agent really automate Visma NL 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 Visma NL API directly?

The connector adds permission isolation, audit logging, cost tracking per agent, and reversible PII redaction at the LLM boundary. It also presents Visma NL 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 Visma NL's own API costs (if any) and the LLM tokens your agent consumes.

Is my Visma NL data sent to a third party?

No. WorkAist runs in your own infrastructure. Data flows from Visma NL → your WorkAist instance → the LLM you choose. Sensitive fields can be tokenized before reaching the LLM.

What if Visma NL changes its API?

The connector is versioned and published openly. When Visma NL ships breaking changes, we bump the connector version and the marketplace UI surfaces the upgrade as a one-click apply.
