Overview

What is Mqtt Mcp?

Mqtt Mcp is a lightweight Model Context Protocol server that connects LLM agents to MQTT devices, enabling seamless integration of AI-driven workflows with Building Automation (BAS), Industrial Control (ICS), and Smart Home systems. It allows agents to monitor real-time sensor data, actuate devices, and orchestrate complex automation tasks.

How to use Mqtt Mcp?

Install uv, clone the repository, run uv sync to install dependencies, then start the server with uv run mqtt-mcp. The server defaults to the Streamable HTTP transport on port 8000. For Bearer Token authentication, provide an RSA public key in PEM format in the .env file.

Key features of Mqtt Mcp
