Description
n8n-nodes-palveron
Official n8n community nodes for the Palveron AI Governance Gateway
—
Verify prompts, list active policies, and pull governance audit trails into any n8n workflow. Drop the Palveron node anywhere a prompt is built, branch on ALLOWED / BLOCKED / MODIFIED, and ship compliance-ready automation in minutes.
- Community-node-package compliant — installable from the n8n UI without code
- First-class credential type — API key + on-prem base URL
- Per-call audit trail — every operation returns the Palveron trace ID
Installation
From the n8n UI
Settings → Community Nodes → Install → n8n-nodes-palveron.
Self-hosted / manual
cd ~/.n8n/nodes
npm install n8n-nodes-palveron
Then restart n8n.
Credentials
Create a Palveron API credential:
| Field | Value |
|——-|——-|
| API Key | Your pvlive… or pvtest… key |
| Base URL | https://gateway.palveron.com (or your self-hosted gateway) |
The credential is reused by every Palveron node in a workflow.
Node operations
The Palveron node ships with three operations:
| Operation | Purpose |
|———–|———|
| Verify Prompt | Run a prompt through the gateway. Output exposes decision, output, reason, traceId, findings, and latencyMs. Branch on decision. |
| List Policies | Fetch the project’s active guardrails (id, name, prompt preview, environment). Useful for compliance dashboards. |
| Check Health | Gateway readiness probe. Fail-fast workflows can guard on this before they call any model. |
Example workflow
Webhook → Palveron (Verify Prompt) → IF decision == BLOCKED → Slack alert
└→ OpenAI (Chat Completion) → Response
The OpenAI node always reads Palveron → output instead of the raw prompt, so anything the gateway redacted (PII, secrets) never reaches the model.
