get_status and retain the returned account identity, readiness,
blockers, and reachable accounts.
Switch only to an accountId returned by get_status:
notifications/tools/list_changed and call
get_status again. The second read confirms which account is active even when
the client did not refresh its catalog immediately. Omit accountId to return
to the credential’s home account.
Every authenticated Buyer and Seller Account can connect. Tools and resources
still depend on permissions and feature-specific availability. A principal
that can reach both account kinds can receive both tool families at connection
time; their visibility does not authorize them in the wrong selected account.
Organisation accounts currently provide navigation and shared settings rather
than an operational noun catalog.
Your application should retain the account identity with every workflow
checkpoint and verify it when resuming. A connection, a seller relationship,
or a registered agent does not implicitly grant access to every advertiser.
