Governed AI-ops for Nutanix Prism Central (v4 REST API) — clusters, hosts, VMs (AHV + ESXi), storage, network, catalog, data protection / DR, alerts, LCM upgrades, and capacity — with a built-in governance harness: unified audit log, token/runaway budget guard, undo-token recording, and descriptive risk-tier labels. Connects to Prism Central on HTTPS :9440 with HTTP Basic auth (username + encrypted password). Self-contained: no dependencies beyond httpx and the MCP SDK.

Why this over a read-only Nutanix MCP

• Automatic ETag / If-Match on every mutation. The v4 API rejects an update or delete without the entity's current ETag — the classic footgun. This tool fetches and sends If-Match for you.
• Automatic pagination — list tools walk every v4 page for you, and return a {"<items>": [...], "returned", "limit", "truncated"} envelope so a capped read announces itself instead of looking like the whole estate.
• Absent is not empty — a field Prism Central did not return comes back as null, never as "". v4 omits a lot of fields; the two facts stay distinct.
• Mixed-hypervisor VM listing — vm_list returns both AHV and ESXi guests under the same Prism Central (built for hypervisor-migration estates).
• Governance harness — audit / token+call budget / descriptive risk-tier labels / undo-token / prompt-injection sanitize, with dry-run + double-confirm on destructive writes.

What this tool does, and does not, decide

It delivers Nutanix Prism Central 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: connect with a Prism Central account holding only a read-only (Viewer) role, 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 ~/.nutanix-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.

Running a smaller / local model? See agent-guardrails.md — it lists the guardrails this tool now enforces for you (so you don't spend prompt budget restating them) and gives a ready-made system prompt for what's left.

Capability matrix (51 MCP tools)

Diagnostics / RCA are the flagship reads. cluster_health_rca ranks the whole estate — degraded fault-tolerance state, storage pools and containers over 80% (warning) / 90% (critical), nodes not healthy or missing from inventory — worst-first, each finding citing the measured percentage or raw Prism state that tripped it. alert_triage_rca groups active alerts by severity with a count per level, flags unacknowledged criticals, and surfaces the oldest unresolved alert with its age. Both are read-only (risk_level="low") and deterministic — no clock, no randomness, same input → same answer. analyze_alert complements them at the single-alert level: it correlates an alert with its related events into a probable-cause + suggested-actions summary. High-risk writes (vm_delete, vm_migrate, storage_container_delete, subnet_delete, snapshot_delete, snapshot_restore, pd_failover, image_delete, lcm_update) support dry_run and, at the CLI, double confirmation.

Install

uv tool install nutanix-aiops          # or: pipx install nutanix-aiops

Quick start

As a Claude Code plugin

One install gives an agent both the skill and the MCP server:

/plugin marketplace add AIops-tools/marketplace
/plugin install nutanix-aiops@aiops-tools

The MCP server is fetched with uv and pinned to the package version this plugin declares, so an audit row can be traced back to the code that wrote it. Credentials are still configured with nutanix-aiops init — see below.

As an OpenClaw plugin

The same bundle is published on ClawHub, where one install delivers the skill and its MCP server together:

openclaw plugins install clawhub:@zw008/nutanix-aiops
openclaw skills info nutanix-aiops          # expect: Visible to model: yes

Restart the OpenClaw gateway afterwards so it loads the plugin. The MCP server is fetched with uv, pinned to this exact release, so uvx has to be on PATH — without it the skill still installs but reports Visible to model: no. Credentials are configured exactly as below.

As a CLI or standalone MCP server

nutanix-aiops init                     # wizard: PC host / port 9440 / username / verify_ssl + encrypted password
nutanix-aiops doctor                   # config, secrets, connectivity + REST-RBAC preflight
nutanix-aiops overview                 # one-shot estate summary
nutanix-aiops diagnose cluster-health  # worst-first RCA: resiliency, storage, nodes
nutanix-aiops vm list                  # AHV + ESXi VMs

Run as an MCP server (stdio):

export NUTANIX_AIOPS_MASTER_PASSWORD=...   # unlock the encrypted secret store non-interactively
nutanix-aiops mcp

Where that password then lives: an exported variable is readable by every process this shell starts and is recorded by shell history. On a shared or long-lived host, prefer the interactive prompt, or inject it from a secret manager for the life of the one command that needs it.

CLI

nutanix-aiops (Typer): init, overview, doctor, mcp; cluster list/health/hosts/util; vm list/get/power/delete/migrate (delete & migrate take --dry-run + double confirm); diagnose cluster-health, diagnose alert-triage; secret set/list/rm/migrate/rotate-password. The CLI is a convenience subset — the full 51-tool surface is via the MCP server.

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 ~/.nutanix-aiops/audit.db (relocatable via NUTANIX_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 NUTANIX_RUNAWAY_MAX=0; optional hard ceilings via NUTANIX_MAX_TOOL_CALLS / NUTANIX_MAX_TOOL_SECONDS.
• Undo recording — reversible writes record an inverse descriptor built from the fetched before-state (vm_update → prior CPU/memory, vm_migrate → prior host).
• Risk tier — a descriptive label on the audit row derived from risk_level; it gates nothing.

Credentials

The Prism Central password is stored encrypted in ~/.nutanix-aiops/secrets.enc (Fernet + scrypt) — never plaintext on disk. Unlock with a master password from NUTANIX_AIOPS_MASTER_PASSWORD (MCP/CI) or an interactive prompt (CLI). The non-secret connection details (host, port, username, verify_ssl) live in ~/.nutanix-aiops/config.yaml. A legacy plaintext env var NUTANIX_<TARGET>_PASSWORD is honoured as a fallback.

Gotcha: the Prism Central account needs REST API rights, not just Web UI access. doctor's REST-RBAC preflight catches this early.
