MCP Supabase agent – manage your database with AI

Hi, I’m Amanda 🌷 This workflow was built with love to help you manage your Supabase database using natural language, powered by the MCP (Multi-Channel Protocol) AI Agent on n8n.

With just a message like “update the status to active where city is New York”, your agent will know exactly what to do — safely, step by step, and always asking for confirmation before deleting anything.

It’s ideal for developers who want a smart assistant to create, update, delete or search database records without writing SQL or opening Supabase.
