How do I install MsgMesh?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

The publisher lists these environment variables: MQ_API_KEY, MQ_CONTROL_PLANE_URL, MQ_GATEWAY_URL, MQ_REALTIME_URL.

What transport does MsgMesh use?

MsgMesh runs locally over stdio.
