Show HN: MCP-enabled file storage for AI agents, auth via Ethereum wallet (service.c33b.org)

A new tech demo has been launched showcasing MCP-enabled file storage, enabling AI agents to manage files in a developer-like manner—performing actions such as reading, writing, and uploading. The service, accessible at service.c33b.org, allows users to quickly provision an account using an Ethereum wallet, facilitating an easy trial with no credit card or lengthy setup. This demonstration highlights how AI agents can interact with data using a structured tool interface while maintaining accessibility through standard FTP over TLS clients. The significance of this development lies in its potential to streamline AI workflows by providing a flexible, decentralized way to handle file management, embracing the growing trend of integrating blockchain technology into AI applications. Users can extend the demo with tailored configurations, opt for custom deployments on their infrastructure, or even run the setup on-premises. The Model Context Protocol (MCP) simplifies authentication using Ethereum wallet signatures, eliminating traditional password methods, while ensuring compatibility with various AI clients, including Claude and Codex. This innovation not only opens avenues for enhanced AI capabilities but also promotes data ownership and control in evolving digital environments.
