Governed AI-ops for a self-hosted observability stack in one server — Prometheus (HTTP API, PromQL, targets, rules, alerts), Alertmanager (alerts + silences), Grafana (dashboards, datasources, folders), and Grafana Loki (bounded LogQL log reads + log RCA) — with a built-in governance harness: unified audit log, token/runaway budget guard, undo-token recording, and descriptive risk-tier labels. One config can span your whole stack; each target names its own platform. Beyond the mock test suite, the Prometheus/Alertmanager/Grafana reads, the RCAs, and the governed silence + dashboard write paths (with undo) have been exercised against a live Prometheus 3.x + Alertmanager + Grafana 13 stack — see docs/VERIFICATION.md.

This is the self-hosted-observability complement to enterprise monitoring suites: it speaks the open Prometheus/Grafana APIs an SRE actually runs, not a vendor NMS.

What it does

Answers the questions an SRE actually repeats over a Prometheus/Grafana stack, and guards the writes that follow:

• PromQL + metadata — instant and range queries, label-value enumeration, and series metadata, all read-only and result-capped.
• Scrape-target & rule health — which targets are up/down (and why, from lastError), which were dropped by relabeling, and which recording/alerting rules are erroring.
• Alerts & silences — firing/pending Prometheus rule alerts, Alertmanager's post-routing view, and its silences.
• Grafana — dashboards, datasources (+ health), and folders.
• Loki logs — bounded LogQL reads (label + label-value enumeration, a validation-gated query_range, and a canned error-tail), all read-only with a hard lookback + line cap, optional multi-tenant X-Scope-OrgID, and basic/bearer auth per target.
• Flagship analyses — transparent heuristics that show their numbers: firing_alert_rca (join each firing alert to its rule expr → cause + action), target_scrape_health_analysis (rank down/erroring scrapes → likely cause), alert_noise_and_flap_analysis (frequently-repeated / duplicate alerts → dedup/rollup recommendation), plus two log analyses — log_error_burst_rca (per-stream error burst vs baseline → new-signature / volume-spike / single-instance) and log_volume_analysis (top streams + high-cardinality label warnings + retention hint) — and alert_log_context, which correlates a firing Prometheus alert to its Loki streams.
• Governed writes — create/expire Alertmanager silences (time-boxed), create Grafana annotations, update/delete dashboards, and hot-reload the Prometheus config — each audited, risk-tiered, dry_run-able, and the reversible ones capture the real fetched before-state for undo.

What this tool does, and does not, decide

It delivers Prometheus + Grafana operations — reads and writes — accurately and efficiently, and records every one of them. It does not decide whether a write is allowed to happen. That is the agent's judgement, or the permission of the account you connect it with: give it a Grafana token with only Viewer scope, and a Prometheus/Alertmanager reached without the admin/write API, and the writes fail at the server — the place that actually owns the permission.

So there is no read-only switch, no policy file, no approval gate to configure. The one thing the tool guarantees is that nothing is silent: every call, over MCP and over the CLI alike, lands an audit row in ~/.observability-aiops/audit.db, and destructive writes still capture their before-state and record an inverse where one exists.

Each tool declares a risk_level, carried into the audit row as a descriptive tier (none/confirm/review) — so a reviewer can see at a glance that a row was a high-risk delete. It is a label, not a gate.

Capability matrix (39 MCP tools)

Loki is read-only — Loki exposes no safe operational write surface (no silence/annotation analogue), so this tool deliberately ships no Loki writes.

The CLI exposes a convenience subset (query, logs, alert, overview, …); the full 39-tool surface is via the MCP server.

Quick start

uv tool install observability-aiops          # or: pipx install observability-aiops
observability-aiops init                     # wizard: pick platform (prometheus/grafana) + store the token (encrypted)
observability-aiops doctor                   # verify config, secrets, connectivity
observability-aiops overview                 # snapshot: firing alerts + targets up/down + rules erroring
observability-aiops query instant 'up'       # run a PromQL instant query
observability-aiops logs errors '{app="api"}' # tail error-level Loki logs (bounded)
observability-aiops alert rca                # root-cause the firing alerts

Run as an MCP server (stdio):

export OBSERVABILITY_AIOPS_MASTER_PASSWORD=...   # unlock secrets non-interactively
observability-aiops mcp

Governance

Every MCP tool passes through the bundled @governed_tool harness:

• Audit — every call (params, result, status, duration, risk tier, and any operator-supplied approver/rationale) is logged to ~/.observability-aiops/audit.db (relocatable via OBSERVABILITY_AIOPS_HOME). The CLI writes the same row the MCP path does — there is no unaudited entry point.
• Runaway guard — a safety backstop, not an authorization gate: the same call hammered in a tight loop trips a circuit breaker. Disable with OBSERVABILITY_RUNAWAY_MAX=0; optional hard ceilings via OBSERVABILITY_MAX_TOOL_CALLS / OBSERVABILITY_MAX_TOOL_SECONDS.
• Undo recording — reversible writes record an inverse descriptor built from the fetched before-state (create_silence→expire, update_dashboard/delete_dashboard→restore the captured prior model).
• Risk tier — a descriptive label on the audit row derived from risk_level; it gates nothing.

Supported scope & limitations

• Platforms: Prometheus HTTP API (+ a companion Alertmanager), Grafana HTTP API, and Grafana Loki HTTP API (read-only). Hosted/SaaS monitoring suites (Datadog, New Relic, enterprise NMS) are deliberately out of scope for this tool.
• Verification. The mock suite covers all four platforms; in addition the Prometheus, Alertmanager and Grafana surfaces have been exercised against a live Prometheus 3.x + Alertmanager + Grafana 13 stack (RCAs, the silence and dashboard governed writes, and undo replay). The Loki surface has not yet been exercised live. All four are free and open-source and trivial to stand up in a lab (docker run prom/prometheus, grafana/grafana, grafana/loki), so observability-aiops doctor is the fastest live check (Prometheus /api/v1/status/buildinfo, Grafana /api/health, Loki /ready + /loki/api/v1/status/buildinfo). See docs/VERIFICATION.md.
