Definition
A public or enterprise directory that scores and vets third-party AI agents, agent skills, and MCP servers — the building blocks teams pull off marketplaces to extend their AI. It gives buyers a security signal about code they cannot easily inspect for themselves.
Why it matters
Teams routinely install third-party agents and MCP servers with no vetting signal, which is exactly how malicious or over-privileged code slips into production; a trust registry provides the missing third-party diligence.
