Questions

Can Memtro change anything in Companies House?
Not yet. Today every Companies House tool reads, searches or lists. When the connector gains actions, each is marked, granted by name per team and used only when a person asks for exactly that, so nothing is created, sent, updated or deleted until you say so.
Who can use a Companies House connection?
A personal connection serves only your own requests. A shared connection serves the organisation: everyone, or only the teams an admin chooses. Admins can always add shared connections; other members need the permission.
Does Memtro store my Companies House data?
Credentials are encrypted at rest. Tool results are cached briefly so agent loops do not repeat identical calls, and the facts the model extracts are saved to your organisation's memory with provenance (system, record and link) so they can be checked and superseded.
How do I connect Companies House?
API key. In Companies House, get API key (A REST key for the public data API. Create an application at developer.company-information.service.gov.uk, then add a key of type "REST" to it.).
