Basic mail server

This is a staging environment email integration that's explicitly marked as work in progress. Based on the naming, it likely exposes email operations through MCP, though the source doesn't detail which APIs or email providers it connects to. It's hosted on Alpic's staging infrastructure and supports both streamable HTTP and SSE transports. Since it's still under active development, you'd only want to check this out if you're comfortable with unstable APIs or want to see what's coming. Wait for a production release if you need reliable email functionality in your Claude workflows.
