FAQ
Can a WorkAist AI agent really automate Companies House (free API) 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 Companies House (free API) API directly?▼
The connector adds permission isolation, audit logging, cost tracking per agent, and reversible PII redaction at the LLM boundary. It also presents Companies House (free API) 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 Companies House (free API)'s own API costs (if any) and the LLM tokens your agent consumes.
Is my Companies House (free API) data sent to a third party?▼
No. WorkAist runs in your own infrastructure. Data flows from Companies House (free API) → your WorkAist instance → the LLM you choose. Sensitive fields can be tokenized before reaching the LLM.
What if Companies House (free API) changes its API?▼
The connector is versioned and published openly. When Companies House (free API) ships breaking changes, we bump the connector version and the marketplace UI surfaces the upgrade as a one-click apply.
