Duplex icons

3 icons carry the tag duplex, across Developer Tools and MCP. gRPC, MCP over WebSocket and WebSocket — each in outline and duotone at three weights, with the code for React, Vue, Svelte, Flutter and more.

The 3 duplex icons, described

gRPCgrpc: gRPC — two services calling each other in binary over protobuf.
MCP over WebSocketmcp-websocket: MCP over WebSocket — a persistent connection that stays open both ways.
WebSocketwebsocket: A WebSocket — a connection opened once and kept open both ways, live.

In code, each is one import — import { Grpc } from "@iconmind/react/icons/grpc" — and the same name in Vue, Svelte, Solid, Preact, React Native, Astro, Blade and Flutter.
