Read-only or a trading bridge
The first question is what the server is allowed to do. A trading bridge connects your exchange account through your own API key so an agent can submit orders. A read-only server returns prices and analysis and never sees an account. PredictionMarketsPicks is read-only: a trade link opens the exchange, and you place any order yourself.
