Nothing serious here today

Today is the operative word: we check MQTT every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

Put your own value in place of <MQTT_HOST> (Broker hostname or IP). The author’s registry entry marks it as required.

Optional settings from the registry entry, left out of the block above: MQTT_PORT (Broker port, default 1883 (or 8883 for TLS)), MQTT_USERNAME (Broker username), MQTT_PASSWORD (Broker password), MQTT_USE_TLS (true/false, default false).

MQTT — questions

Answers built from our own checks of this server.

Why is there no uptime for MQTT?

MQTT runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package mqtt5-mcp-server was installed 92 times last week.

How do I connect MQTT?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls mqtt5-mcp-server straight from pypi; nothing to host, nothing to sign up for.

How many people use MQTT?

The pypi package mqtt5-mcp-server was installed 92 times in the last week. Week over week that is +5%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is MQTT open source?

Yes — it is published under the MIT licence, written in Python and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
