- Its Trust Check reads public metadata without calling tools; owner-verified Deep Scan is described as a separate, more involved check.
Field notes
The page separates a Trust Check of public tool, prompt, and resource definitions from a Deep Scan for owner-verified servers. It says scans are diffed against previous results to catch tools that change after approval, and that Deep Scan uses test inputs with read-only tools. The methodology is public; the site characterizes its grades as automated heuristic assessments rather than penetration tests or legal certification.
