Tools

• get_vulnerability ~151 tokens
  Get full detail for a single vulnerability by its OSV ID — e.g. "GHSA-jf85-cpcp-j695", "CVE-2021-23337", "PYSEC-2021-XXX". Returns summary, details, aliases, severity, affected packages/ranges, and references. Keyless.
• query_batch ~232 tokens
  Batch vulnerability query against OSV.dev (up to 1000 entries per call) — for SBOM-style "scan every dependency in this lockfile" workflows. Pass an array of {package:{name,ecosystem}, version?} or {commit} entries. Returns the vuln IDs matched per query (use get_vulnerability for full detail per ID
• query_by_commit ~144 tokens
  Find vulnerabilities affecting a specific source-repository git commit via OSV.dev. Useful when you have a pinned commit hash rather than a released version. Returns the same compact vuln summary array. Keyless.
• query_package_vulns ~272 tokens
  Find all known vulnerabilities for an open-source package, optionally at a specific version, via the OSV.dev database. Omit version to get every vuln known for the package. Returns a compact summary array (id, summary, aliases, severity, references). Keyless.
