n8n-nodes-ujex

Three community nodes for n8n wrapping the Ujex agent backend:

• Ujex Postbox — send DKIM-signed email through a Ujex agent inbox. PI-scored. Audit-chained.
• Ujex Approvals — pause the workflow until a human decides in Ujex.
• Ujex Memory — markdown agent memory. Write / read / search / list. No vector DB.

One self-hostable backend for agent email, approvals, and memory. Apache-2.0.

Install

n8n install --community n8n-nodes-ujex
# or npm i n8n-nodes-ujex inside ~/.n8n/custom

Credentials

Create a "Ujex API" credential with:

• Cloud Functions URL (e.g. https://us-central1-axy-ujex.cloudfunctions.net)
• Agent device key (mint in Ujex dashboard → Settings → Agents → Keys → New)
• Agent ID
• Firebase Web API key (leave the default for ujex.dev)

For sends, pass a stable Session ID for the workflow run. Ujex uses it for
prompt-injection poisoning, exfiltration checks, and budget preflight.
