POST /tools/package-dependency-risk-scanner

blocked

Give it npm or PyPI package names. For each it reads the registry metadata and latest version (and npm download counts) and queries OSV.dev for known security advisories, then composes a risk brief: known vulnerabilities, deprecation, staleness and a signal. Keyless, agent-callable. One search per call (result caps in the input schema); failed lookups are not charged.

Verdict: not verified by an unpaid GET. 401/403/429: auth or bot protection. This says nothing about whether the route works when called as declared.
