A side-by-side look at the Bigiron and Carbon MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Bigiron for industrial & iot work as a local process; choose Carbon for industrial & iot. You can also run both side by side in one mcpServers block.
