Fastmail just announced that they have added MCP support, so that AI can access your mail. How nuts is that for a 'privacy focused' email service.
So I've decided to migrate. Maybe to your service, but I have to be sure that you'll never allow AI to access my data, no matter if I want that voluntarily.
For me it's fundamentally wrong to add such access, even when it's optionally.
