What MCP Is Not
MCP is not magic. A server can only expose what the underlying service makes available. If your email provider’s API doesn’t support attachments, the MCP server can’t read attachments. The server is a bridge, not a bypass.
MCP is also not a security boundary. When you install an MCP server, you’re giving Claude access to whatever that server can reach. Think about what permissions the server needs and whether you’re comfortable with those. The same judgement you’d apply to any other integration.
