Automates Supabase operations through Composio's Rube MCP integration, covering database queries, table management, SQL execution, project administration, and edge functions. You'll want this if you're managing Supabase programmatically instead of clicking through the dashboard. The skill requires Rube MCP connected first, then walks you through authenticating your Supabase connection before running workflows. Notable detail: project refs must be exactly 20 lowercase letters, and SELECT_FROM_TABLE is read only, so you need RUN_SQL_QUERY for writes. Watch out for PostgreSQL array syntax quirks and the fact that API key retrieval returns live secrets. Covers the full Supabase API surface with detailed PostgREST filter operators and schema inspection tools.
