# v3 Account Access

> Understand the active account, reachable accounts, enrollment, and safe account switching in v3.

v3 resolves its tool catalog from the authenticated account. Begin every new
session with `get_status` and retain the returned account identity, enrollment
state, blockers, and reachable accounts.

Switch only to an `accountId` returned by `get_status`:

```json theme={null}
{ "accountId": 624 }
```

After switching, process `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.

Buyer and Seller accounts receive their account-specific tools when enrolled.
Organisation accounts currently provide navigation and shared settings rather
than an operational noun catalog.
