AWS IoT Core vs Carbon
A side-by-side look at the AWS IoT Core 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 AWS IoT Core 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.
Which MCP server should you choose?
Choose AWS IoT Core when
- You need dedicated capabilities in the Industrial & IoT domain.
- You prefer a local stdio subprocess transport.
Choose Carbon when
- You need dedicated capabilities in the Industrial & IoT domain.
- You have the keys it needs:
CARBON_API_KEY.
