MQTT MCP

What is MQTT MCP?

MQTT MCP is a Model Context Protocol server that connects AI assistants to MQTT message brokers. MQTT (Message Queuing Telemetry Transport) is the de facto standard for IoT communication, used by billions of devices worldwide for lightweight, reliable messaging.

IoT Intelligence

With MQTT MCP, AI models can subscribe to sensor data streams, analyze telemetry patterns, detect anomalies, and even publish control commands to IoT devices. This creates powerful AI-driven IoT workflows.

Features

The server supports MQTT v3.1.1 and v5.0, TLS encryption, authentication, wildcard topic subscriptions, and QoS levels 0-2. It can parse common IoT payload formats including JSON, Protobuf, and raw binary data.

Configuration

{
  "mcpServers": {
    "mqtt": {
      "command": "npx",
      "args": ["mqtt-mcp"],
      "env": {
