Watch out for

• It can delete caches and replication groups

  Three tools delete serverless caches, replication groups and clusters. Use the readonly flag or a read-only IAM policy unless you need changes. github.com

• It can create caches and EC2 hosts and open network access

  It can create caches and EC2 jump hosts and edit security group rules. Use an IAM policy that limits these actions. github.com

• It can create caches with a public endpoint

  The README suggests denying elasticache:CreateServerlessCache when the connection type is public, so a cache cannot be exposed to the internet. github.com
