prometheus-mcp (official)
access level: configurable✔ Source-reviewed Oct 2026
We read this project's source code and tool definitions (Oct 2026). This is a code review, not a live test against real systems. Re-check after upgrades.
| Repository | https://github.com/prometheus/prometheus-mcp |
|---|---|
| Category | Observability |
| Systems touched | Prometheus (and Thanos-compatible backends): PromQL, labels/series, alerts/rules/targets, docs, admin |
| Access (as described) | configurable |
| License / price | Apache-2.0 / free |
| GitHub stars | 137 |
| Read tools | query, range_query, label_names/values, series, metric_metadata, list_alerts/rules/targets, build_info, config, flags, runtime_info, healthy/ready, docs_*, runbooks_*, tsdb_stats, exemplar_query, … |
| Write / delete / exec tools | reload, quit; TSDB admin (delete_series, clean_tombstones, snapshot) only with --dangerous.enable-tsdb-admin-tools |
| Read-only mode | Partial: --mcp.tools whitelist; TSDB admin off by default; core query/docs tools always loaded; use a read-only Prometheus reverse-proxy or auth for hard readonly |
| Safety notes | Do not pass --dangerous.enable-tsdb-admin-tools unless you really mean it. reload/quit can disrupt scraping — drop them via --mcp.tools if the agent should only query. Prefer this official server over one-off forks when starting fresh. |
| Verified | yes (README review 2026-11-07) |
| Notes | Official Prometheus org server (supersedes community-only options for many users). Embeds Agent Skills/runbooks. Actively updated (push 2026-11-05). Added 2026-11-07. Sibling still listed: pab1it0/prometheus-mcp-server. |
