This is a straightforward file persistence layer that lets Claude upload, download, and version files through the uldl.sh service. You get basic CRUD operations for file storage without needing to wire up your own S3 buckets or local filesystem access. Reach for it when you need Claude to save generated files, retrieve previous versions, or maintain state across conversations. It runs over streamable HTTP and works with standard curl commands, so integration is minimal. Good fit for prototyping workflows where Claude needs to remember files between sessions or share outputs that outlive the chat context.
