The curl command-line tool now supports MQTTS, enabling secure MQTT over TLS connections. This update, detailed in a recent blog post, allows developers to test and interact with IoT brokers using the familiar `curl` interface without needing specialized clients. The addition is part of curl's ongoing expansion into modern protocols.

MQTT is the backbone of many machine-to-machine and IoT systems, but its security often relies on TLS. By adding native MQTTS support, curl simplifies the process of validating broker configurations and endpoints. This move aligns with the tool's broader mission to be a universal protocol client for developers and system administrators.

Looking ahead, this feature will likely be integrated into automation scripts and debugging workflows for IoT platforms. As MQTT adoption grows in industrial and consumer applications, having a trusted, ubiquitous tool like curl to handle secure connections is a practical win for the developer community.
