Governed AI-ops for GPU inference clusters — vLLM (OpenAI API + Prometheus /metrics) and Ray Serve / Ray Jobs (Ray dashboard), plus the single-process serving engines SGLang and TGI (Text Generation Inference) — with a built-in governance harness: unified audit log, policy engine, token/runaway budget guard, undo-token recording, and descriptive risk-tier labels on every audit row. It parses each engine's Prometheus /metrics directly (no Prometheus server required) and probes the Ray dashboard independently. A bearer token is optional (many stacks run open).

Serving engines. vLLM is the flagship (full Ray Serve control plane: scale, drain, autoscale, LoRA, hot-swap). SGLang and TGI are supported for engine-agnostic observability — health, running-model identity, request-latency metrics, queue depth, and latency RCA — read from each engine's own endpoints and metric names. Being single-process servers, they have no Ray-shaped scale/drain API: those writes return a teaching error pointing you at a real horizontal-scale layer (Ray Serve / Kubernetes / a load balancer).

What it does

The flagship value is root-cause analysis, wrapped in guarded reads and writes:

climbs, it correlates queue depth (running vs waiting), KV-cache pressure / preemptions, and prefix-cache locality into a ranked cause plus the specific knob to turn (add replicas, raise max-num-seqs, fix routing, enlarge KV cache). Every flag is a number, not a black-box verdict.

• diagnoselatencyspike (flagship RCA) — when TTFT/TPOT/e2e latency

replicas, or routing that strands a cache-warm replica → what to scale down.

• diagnoselowutilization — the inverse: idle GPUs, over-provisioned

Prometheus/Grafana deployment needed.

• Prometheus-native — reads vLLM's /metrics endpoint directly; no

audit + budget + risk-tier approval + undo-token + prompt-injection sanitize, with dry-run + double-confirm on the fragile prod ops (scale-down, scale-to-zero, drain, redeploy, hot-swap) the community reports as dangerous.

• Governance-grade — the first governance-grade entrant in this niche:

or CPU-mock + Ray in one local container (ray start --head).

• Laptop self-test — ~80% of the tool self-tests free: vLLM on a single GPU

What this tool does, and does not, decide

It delivers inference-cluster 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 environment you connect it with: restrict the network path so it can only reach the read/metrics endpoints, or run the Ray dashboard without its job-submission 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 ~/.inference-aiops/audit.db, and destructive writes still capture their before-state and record an inverse where one exists.

Each tool declares a risk_level, kept in agreement with its [READ]/[WRITE]

documentation tag by a test, and carried into the audit row as a descriptive

tier — so a reviewer can see at a glance that a row was a high-risk

scale-to-zero. It is a label, not a gate.
