check-system-health from prometheus/prometheus-mcp is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add prometheus/prometheus-mcp/check-system-health@git:20260721.4db318bPins git:20260721.4db318b in mdr.lock. Pin the fingerprint instead.

Health-check the Prometheus server and its targets. Use for status, uptime, or is-monitoring-OK questions; reviews readiness, active alerts, target health, TSDB stats, and runtime info.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Understanding System Health Build an overall picture of whether Prometheus itself is healthy and whether it is successfully monitoring what it should. A good health check covers the server, its targets, and the data being collected. ## Getting oriented - healthy and ready report whether the server is up and able to serve queries. - build_info and runtime_info identify the version, storage retention, and runtime settings; flags exposes the full command line. - list_targets shows every scrape target and its health; list_alerts shows what is actively firing. - tsdb_stats summarizes series counts, cardinality, and ingestion (the load side of the picture). - query Prometheus's self-monitoring metrics directly: rate(prometheus_tsdb_head_samples_appended_total[5m]) shows ingestion throughput, and counters like prometheus_rule_evaluation_failures_total or prometheus_notifications_dropped_total should sit at zero -- any steady rate on them is a problem in itself. ## Topics worth exploring Treat these as starting points and follow what the data shows: - Firing alerts: anything already alerting is the fastest pointer to known problems; the labels identify the affected services. …

How to install
mdr add prometheus/prometheus-mcp/check-system-health@sha256:b65d3c62b121e17fThe line at the top of this page pins the label git:20260721.4db318b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
