MIT self-hosted store for AI-agent skills (TypeScript) that keeps your scattered markdown skills versioned in one place and serves them over MCP with client-key authentication, so any agent can pull the skill it needs instead of you copy-pasting instructions between projects. It runs via Docker with no mandatory paid dependency; optional skill-recommendation features can use a paid AI provider but are not required for the core.
Once a team runs agents in more than one place, the skills sprawl: the same markdown instruction copied into three repos, drifting out of sync. skillbox makes it one versioned, self-hosted source the agents pull over MCP, so a skill is written once and reused everywhere, with auth on who can fetch it. In the agent-skills stack this registry is tracking, it is the manage-and-serve layer that sits next to scanning a skill before install and gating what it can do at runtime. The honest read: it is young and thinly committed, and its own README is written for an agent to action rather than a person, so treat it as an early but useful piece, and remember it serves skills without vetting them.
