How it works:

• OpenClaw receives user messages, routes them through a multi-agent system
• n8n handles deterministic tasks (API calls, data writes, lookups) via MCP -- zero tokens spent
• PostgreSQL persists n8n workflows, credentials, and execution history
• AI handles reasoning; n8n handles everything else

# 1. Clone
git clone https://github.com/lorenzespinosa/openclaw-n8n-stack.git
cd openclaw-n8n-stack

# 2. Configure
cp .env.example .env
# Edit .env — set POSTGRES_PASSWORD, N8N_ENCRYPTION_KEY,
# OPENCLAW_GATEWAY_TOKEN, and at least one AI provider key

# 3. Deploy
docker compose up -d

# 4. Verify
docker compose ps          # All 3 services should be "healthy"
curl http://localhost:5678/healthz    # n8n
curl http://localhost:18789/healthz   # OpenClaw
