Kafka Sentinel runs on your own machine — the client starts it, so there is no endpoint to ping. 125 installs a week from pypi. Last commit 31 Jul 2026.
Read-only Kafka observability MCP server: cluster health, consumer lag, and replay-readiness.
Nothing serious here today
Today is the operative word: we check Kafka Sentinel every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
