You can set up a Schwab brokerage account internationally and then use it to buy money market funds.
For a German investor that's not a good option for two reasons:

2. Using a foreign broker is a tax nightmare in Germany.
Apart from that the German broker market is highly competitive with multiple choices where you can buy European money market funds basically for free.
