Which integrations are available for this server?

Connects to MQTT brokers for smart home automation and IoT device control, allowing discovery of topics, reading sensor values, sending commands, and monitoring real-time events.

How do I use MQTT MCP Server?

1. Click on "Deploy Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@MQTT MCP Server turn on the living room lights" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

For any MCP client that supports stdio transport:

1. Install the package:

pip install mqtt-mcp-server

2. Configure with these values:

Command: python (not python3)
Args: ["-m", "mqtt_mcp.server"]
Environment variables:
- MQTT_HOST - Your broker IP/hostname
- MQTT_PORT - Broker port (usually 1883)
- MQTT_USERNAME - Optional username
- MQTT_PASSWORD - Optional password

Available Tools

After installation, ask your AI assistant: "What MQTT tools are available?"

You should see 4 tools:

`topics`

Discover MQTT topics on your broker.

Parameters:
- scan_timeout: Scan duration in seconds (1-60, default: 10)
- keywords: Filter topics by keywords
- limit: Max results (1-200, default: 50)

`value`

Read current values from topics (uses cache for speed).

Parameters:
- topics: List of topic paths (required)
- timeout: Wait time per topic (1-60, default: 5)

`publish`

Send commands to MQTT devices.

Parameters:
- messages: List of {topic, payload, qos, retain}
- timeout: Network timeout (1-30, default: 3)

`record`

Monitor MQTT events in real-time.

Parameters:
- timeout: Recording duration (1-300, default: 30)
- topics: Specific topics to monitor
- keywords: Filter by keywords

Troubleshooting

"python3 not found" (Windows)

Use 'python' instead of 'python3' in all commands

"Connection refused"

1. Check MQTT broker is running
2. Verify MQTT_HOST and MQTT_PORT are correct
3. Check firewall settings
4. Test connection: mosquitto_sub -h YOUR_HOST -p 1883 -t "#"

"Module not found: mqtt_mcp"

Install the package: pip install mqtt-mcp-server
If using venv, make sure it's activated

Tools not appearing

1. Restart your AI client
2. Check JSON syntax in config file
3. Verify connection: claude mcp list (or codex mcp list)
4. Check logs (location depends on client)

Permission errors (Linux/macOS)

Use pip3 install --user mqtt-mcp-server
Or install in virtual environment
