AI Chat Agent - n8n + Anthropic API (Production Stack)
Two-workflow system built for AI-powered client communication. The simpler agent handles end-to-end chat: webhook intake → client config fetch → conversation history retrieval → dynamic prompt assembly in JavaScript → Anthropic API call → persist user message and assistant reply → upsert lead in CRM → respond to webhook.
The production-grade version layers in enterprise reliability: JWT auth, rate limiting, full context window management, Claude tool-use routing across five parallel integrations (vector KB search, CRM lookup, Google Sheets, Calendar booking, SendGrid), sentiment analysis for escalation detection, Slack alerting, and BigQuery analytics logging. Every node runs retry logic with on-error-continue paths for graceful degradation.
Both systems are live and handling real traffic. Stack: n8n · Anthropic API · Supabase · HubSpot · Pinecone · SendGrid · BigQuery · Slack.
