Show HN: Sx – an open-source package manager for AI skills, MCPs, and commands

Sx is an open-source package manager that enables teams to share AI skills, MCPs (Model Context Protocols), and commands through a shared folder synced via Dropbox, Google Drive, or similar services—without requiring servers, Git knowledge, or accounts. The tool offers both a user-friendly desktop app and command-line interface, allowing AI assets to be versioned, distributed across all AI tools a team uses, and scoped to specific organizations, repositories, or users. It solves the problem of AI assets drifting out of sync when copied between projects by providing a single source of truth for asset management and distribution.
