Dependency Trust

Get a security advisory (vulnerability) by its key. Returns a security advisory by key, for example a GHSA id taken from a version's advisoryKeys, including the title, CVE aliases, CVSS v3 score and vector, and a link to the full record on osv.dev. Use this only when you already have an advisory ID from get_package_version's advisoryKeys. There is no search here. To find out whether a version has vulnerabilities at all, call get_package_version first; this tool explains one advisory in depth.

Get the resolved dependency graph for one package version. Returns the full resolved dependency graph (direct and indirect) for a version. Each node has the dependency's exact version and its relation (SELF / DIRECT / INDIRECT). Use it to reason about transitive dependencies and supply chain.

List every version of a package and whether each is deprecated. Returns all published versions of a package with publish date, the default-version flag, and deprecation status. Use it to find the latest version or check if a package is deprecated. Coding agents should call this before recommending a package or version.

Get license, security advisories, and source links for one package version. Returns detailed metadata for a single version: SPDX licenses, security advisoryKeys (known vulnerabilities), homepage/issue-tracker/source-repo links, registries, publish date, and deprecation status. Pass any advisoryKey returned here to get_advisory for the vulnerability details.

Get a project's OpenSSF Scorecard security posture and maintenance signals. THE trust check. Returns supply-chain trust signals for a package's source repository: the OpenSSF Scorecard overall score (0-10) and per-check results (Maintained, Code-Review, Signed-Releases, Branch-Protection, Pinned-Dependencies, Dangerous-Workflow, Token-Permissions, Security-Policy, Vulnerabilities, ...), plus stars, forks, open-issue count, and license. Use it to judge whether a dependency is actively maintained and securely operated, not just whether it has a known CVE. Get the projectKey from a version's SOURCE_REPO link (call get_package_version first), e.g. 'github.com/facebook/react'.
