### Describe the issue

### Issue details

```shell
I installed the DXB Interact Brain MCP and successfully authorized it using my account. Everything worked perfectly at first.

However, after a few days, I can no longer authorize the MCP. It now requires me to use a new business email address.

Does this mean I need to create a completely new account in order to continue using the MCP? If so, this creates a problem because I will not be able to link my broker card to the new account, as it is already linked to my existing DXB Interact account.

Could you please advise what I need to do to restore access to the MCP using my existing account?

There was no information in the MCP connection or setup instructions indicating that I would need to switch to a different account or use a new business email address after the initial authorization.
```

### Expected behavior

I expected the MCP to continue authorizing with my existing DXB Interact account, using the same email address I successfully used during the initial setup.

I also expected to be able to reconnect or re-authorize the MCP without creating a new account, especially since my broker card is already linked to my existing account.
