Best MQTT MCP Servers
MQTT is a lightweight messaging protocol for IoT devices that enables efficient communication in low-bandwidth, high-latency, or unreliable networks. It uses a publish/subscribe model and is designed for constrained devices and networks.
Why this server?
Provides MQTT Sparkplug bridge for Industrial IoT integration, enabling secure communication with MQTT-based industrial automation systems through the SINT Protocol.
AlicenseAqualityCmaintenanceSecurity-enforcing MCP proxy that sits between an AI agent and any number of downstream MCP servers, intercepting every tool call through a capability-token policy gateway that can allow, deny, or escalate to human approval before the call reaches any real tool. It also exposes built-in operator tools for approval workflows, audit trail queries, token management, voice/HUD output, and hierarchicalLast updated12214Why this server?
