Does this mean, the client (UI) needs to be aware that the A2UI data it is receiving is sourced from A2UI over MCP?

yeah something needs to translate what would be A2A messages of A2UI to MCP instead

Is inlineCatalogs also supported for Option A as a per-session catalog?
If so, can we add that in the example for option A just to be clear?

lets do this in another PR, we need a sample working showing it in practice. the MCP samples i look at werent completely clear how this works

How does the catalog negotiation actually take effect?
Is there any framework support that prescribes a certain behavior spec for uniformity?
The get_hello_world_ui tool call seems to simply return a payload regardless of the catalog negotiation that is expected to precede the tool call (or to be inline with the call).

lets make a sample of this and check it in, and then update these docs

Is there also a scenario we can add here where the response will translate to a surfaceUpdate/dataModelUpdate to update the state of the A2UI Surface?
E.g., the button will be disabled and updates its label (or simply the surface updates to a completed state).

we need to figure that part out, agree this is a TODO
