My calendar-mcp server now sends and receives email attachments. It is a little awkward, because either (a) the agent uses base64 or (b) the agent uses curl to up/download the attachments outside of the MCP protocol. Sadly, MCP just doesn't have the features to efficiently handle binary content. #ai #mcp
