Wraps the rustypaste API for managing paste and file hosting operations. You get seven tools covering the standard workflow: paste text snippets, upload files from local paths, set expiry times for auto-deletion, create one-shot links that expire after a single view, shorten URLs, and fetch remote files to rehost them. Requires a rustypaste instance URL and auth token in your environment config. Useful when you need to programmatically share code snippets, logs, or files through a self-hosted paste service instead of manually uploading through a web interface.
