Defaults to 7 MiB so a full-size clipboard_write survives worst-case JSON escaping; 0 disables the guard.; MCP_SESSION_MODE: HTTP session mode: 'auto', 'stateful', or 'stateless'. 'auto' resolves to 'stateful'. This server defaults to 'stateless'.; CLIPBOARD_READ_ONLY: Serve the clipboard read-only.
