Verdict: choose PostgreSQL Performance (read Only) for databases work over a hosted endpoint; choose Supabase MCP Server for databases as a local process. You can also run both side by side in one mcpServers block.
SUPABASE_PROJECT_REF, SUPABASE_DB_PASSWORD, SUPABASE_REGION, SUPABASE_ACCESS_TOKEN, SUPABASE_SERVICE_ROLE_KEY, QUERY_API_KEY.Rows where the two servers differ are marked.
