Gives Claude the ability to upload files to decentralized storage and get back permanent URLs. Exposes four tools: upload_file handles both local paths and inline content, upload_from_sandbox generates curl commands for sandboxed environments, get_file retrieves metadata and permalinks, and get_pricing shows current storage costs. Requires a free API key from objekt.sh. Useful when you need Claude to persist generated files, share outputs beyond the conversation, or create publicly accessible assets without managing your own hosting infrastructure.
