AI-powered TrueNAS SCALE storage operations with a built-in governance harness — unified audit log, token/runaway budget guard, undo-token recording, and descriptive risk tiers. Speaks both TrueNAS APIs: REST v2.0 and the JSON-RPC/WebSocket API that replaces it in TrueNAS 26.

Verification status: live-verified against a real TrueNAS SCALE 25.04.2.1 appliance over both transports, including a full write → audit → undo → verified-restore loop. Coverage is listed endpoint by endpoint — and so are the gaps — in docs/VERIFICATION.md. Read it rather than reading "verified" as "everything".

Supported TrueNAS versions — and which API you are speaking

truenas-aiops speaks both TrueNAS APIs and picks the one that will still exist:

Set transport: per target in config.yaml:

targets:
  - name: nas1
    host: nas1.example.com
    transport: auto        # default — probe /api/current, prefer WebSocket
    # transport: websocket # pin the API that survives TrueNAS 26
    # transport: rest      # pin REST while migrating

auto probes /api/current with a cheap HTTP upgrade (no credential spent). If the appliance offers it, the tool uses it; otherwise it falls back to REST, which is still correct on 25.10 and older.

iXsystems documents that upgrading to TrueNAS 26 revokes existing API keys — so expect to mint a new one after the upgrade. We have not reproduced this ourselves; it is reported here from the upstream release notes, not from a verified upgrade. Treat it as a caution, not a measurement.

truenas-aiops doctor tells you which transport the connection actually used, reads the server version, and — on REST — says plainly whether REST is supported, deprecated, or gone. If the version cannot be parsed it reports UNKNOWN, never a clean bill of health it cannot justify.

What works

• CLI (truenas-aiops ...): init, overview, system, pool list/get/status/scrub-status/capacity/scrub-start, dataset list/get/create, diagnose pool-health/alerts, snapshot list/create/delete, disk list/smart, alert list, service list/restart, replication list/cloudsync, secret set/list/rm/migrate/rotate-password, doctor, mcp.
• MCP server (truenas-aiops mcp or truenas-aiops-mcp): 25 tools (19 read, 6 write), every one wrapped with the bundled @governed_tool harness.
• Encrypted credentials: the TrueNAS API key lives in an encrypted store ~/.truenas-aiops/secrets.enc (Fernet + scrypt) — never plaintext on disk. Unlock with a master password from TRUENAS_AIOPS_MASTER_PASSWORD (MCP/CI) or an interactive prompt (CLI).
• Reversibility: snapshot_create records an inverse snapshot_delete undo descriptor. The irreversible snapshot_delete (high risk) captures the snapshot's BEFORE state for the audit record and declares no undo.
• Safety: destructive CLI ops (snapshot delete, service restart) require double confirmation and support --dry-run.

What this tool does, and does not, decide

It delivers TrueNAS SCALE storage 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: scope the TrueNAS API key to a limited-privilege account and the writes fail at the appliance — 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 ~/.truenas-aiops/audit.db, and reversible writes still capture their before-state and record an inverse.

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 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.

Playbook: triage a degraded pool

truenas-aiops diagnose pool-health            # worst-first: bad state, error counters, capacity
# → e.g. CRITICAL tank "pool status is DEGRADED", and "read=4 checksum=2" on a vdev
truenas-aiops pool status tank                # inspect the topology / scan detail it cited
truenas-aiops pool scrub-start tank           # kick an integrity scrub (governed, medium risk)
truenas-aiops diagnose alerts                 # cross-check active alerts + any datasets near full

Each finding cites the measured number that tripped it (status string, error counts, used-percent) so you see why it was flagged, then points at the exact read/write command to act on it.

Capability matrix (25 MCP tools)

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 truenas-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 truenas-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/truenas-aiops
openclaw skills info truenas-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

uv tool install truenas-aiops
truenas-aiops init        # interactive wizard: connection details + encrypted API key
truenas-aiops doctor      # verify config, encrypted store, connectivity (hits /system/info)

init writes ~/.truenas-aiops/config.yaml (non-secret connection details) and stores the API key encrypted in ~/.truenas-aiops/secrets.enc. Example config it produces:

targets:
  - name: nas1
    host: 10.0.0.30
    port: 443
    verify_ssl: false          # self-signed lab certs only
    api_path: /api/v2.0

Create the API key in the TrueNAS UI under Credentials → API Keys. For non-interactive use (MCP server, CI, cron) export the master password so the store can be unlocked without a prompt:

export TRUENAS_AIOPS_MASTER_PASSWORD='your-master-password'

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.

Managing secrets

truenas-aiops secret set nas1             # prompts hidden for the API key
truenas-aiops secret list                 # names only, values never shown
truenas-aiops secret rm nas1
truenas-aiops secret rotate-password      # re-encrypt under a new master password
truenas-aiops secret migrate              # import a legacy plaintext .env, then deletes it

A legacy plaintext env var TRUENAS_<TARGET_NAME_UPPER>_APIKEY is still honoured as a fallback with a deprecation warning (migrate with truenas-aiops secret migrate).

支持范围 / Supported scope

Versions: TrueNAS SCALE 25.04 and newer over JSON-RPC/WebSocket, and any build still serving REST v2.0 over REST — the transport is selected automatically. See Supported TrueNAS versions. Note that iXsystems documents an upgrade to TrueNAS 26 as revoking existing API keys (upstream claim, not reproduced here).

Read: system info, ZFS pools (list/get/status/scrub-status/capacity), datasets (list/get), snapshots (list), disks + S.M.A.R.T. results, alerts, services, replication & cloud-sync tasks, one-shot health overview, and read-only diagnostics / RCA (pool_health_rca, alert_and_capacity_rca). Mutating (governed, dry-run + double-confirm where destructive): pool_scrub_start, dataset_create, snapshot_create, snapshot_delete, service_restart.

Caveats

• Live-verified against TrueNAS SCALE 25.04.2.1 over both transports — reads cross-checked against the appliance's own API, and a full write → audit → undo → verified-restore loop. What is and is not covered is listed endpoint by endpoint in docs/VERIFICATION.md; read it rather than assuming "verified" means everything.
• Still unverified: S.M.A.R.T. against failing media (needs real hardware — virtio exposes no S.M.A.R.T. at all), replication/cloudsync against real targets, and TrueNAS 26's auth.login_ex (25.04 exercises only the fallback).
• CLI exit codes: 0 confirmed, 1 failed or refused, 2 outcome undetermined (the operation may still be in flight — poll before retrying).
• Out of scope by design: anything that destroys bulk data (dataset/pool deletion, replication runs that overwrite) — only snapshot_delete removes data, and it is high risk + double-confirmed.

Not for

Other NAS/storage or backup products, hypervisor VM lifecycle, container clusters, or network devices — those are out of scope for this tool.
