24/7 Supabase CRM for Less Than ChatGPT Plus

Derek Cheung built a Hermes Agent connected to Supabase that manages real customer data, autonomously proposed and built a new skill from its own reflection, and costs less than a single ChatGPT Plus subscription.

“Less than a single ChatGPT Plus subscription for a 24/7 assistant with real data management. After several interactions, Hermes autonomously proposed a new ‘Supabase MCP scripts’ skill — created from its own reflection.”

— Derek Cheung on YouTube (2026)

Architecture

This setup connects Hermes to a real database (Supabase, a Firebase-like backend-as-a-service), giving it:

• Persistent customer records. Hermes can create, read, update, and delete CRM entries.
• Real data management. Not mock data, not a spreadsheet, but a proper relational database.
• Autonomous operation. Running 24/7 without human intervention.
• Self-improvement. The agent autonomously identified a gap in its capabilities and built a new skill to fill it.

Skill Creation

After several interactions, Hermes noticed a pattern: it kept reaching for the same database operations. It proposed, unprompted, a new “Supabase MCP scripts” skill to make those operations more efficient. It then built that skill itself.

Cost Comparison

Service	Monthly Cost	24/7 Operation	Real Data	Self-Improving
Hermes + Supabase	< $20/mo	Yes	Yes	Yes
ChatGPT Plus	$20/mo	No	No	No
Enterprise CRM	$50-200/mo	No	Yes	No

Setup Steps

1. Set up Hermes. Deploy on a VPS or home server.
2. Create a Supabase account. The free tier is generous enough for small CRMs.
3. Design your database schema. Tables for contacts, deals, interactions, etc.
4. Write MCP (Model Context Protocol) scripts. Give Hermes the ability to query and mutate data.
5. Add your customer data. Import existing records or start fresh.
6. Define workflows. Lead capture, follow-up reminders, deal stage tracking.
7. Let it improve. Hermes will naturally identify gaps and propose new skills.
