Open data: no credential to issue, hold or revoke. It reads the same source a person could look up by hand, at a scale nobody has time to do by hand.
How do you connect Foncier to Claude and ChatGPT?
Through Tulina's own MCP server, not data.gouv.fr's official one or a paid service like Parcellai.re. Geocode an address, read its cadastral parcel and built footprint, check ICPE risk, or pull DVF prices and solar productibility, in the same chat as the site or portfolio review it feeds, whether that chat is Claude or ChatGPT.
Why through Tulina
The connection was never the hard part.
Most systems now publish their own way for a model to reach them, and that is good: it is what Tulina connects to. The hard part is deciding who may use it, what it is allowed to return, and what the model knows before it asks.
The keys stay in one place
YouTeamOrganisation
Connect Foncier once. The credential is encrypted in a vault, never held in clear, and never pasted into a chat or a workflow file. A person uses their own key where they have one, their team's where they do not, the organisation's after that, so nobody is blocked and nobody holds more access than they need. Revoke it once and everything running on it stops.
What leaves is filtered before it leaves

Roles decide who can reach Foncier at all. Beyond that, a policy on the connector itself decides what comes back. The data is minimised at the source rather than after it has already reached a model.
Every call is on the record
whatwhowhen
Runs are logged for the organisation. That is what makes an automated action reviewable after the fact, and it is what a security review asks for first.
The run starts knowing your company
namingkey accountsdecisions
A direct connection gives a model access. It does not tell it how your company names things, which accounts matter, or what was decided last quarter. Tulina carries that across every tool, so the same request against Foncier returns something usable instead of something generic.
