VulnGraph gives coding agents deterministic vulnerability checks

VulnGraph is a tool that turns vulnerability intelligence into deterministic local snapshots, ensuring agents get clear verdicts like 'not-affected', 'unknown', or 'actively exploited' instead of ambiguous booleans. It compiles upstream security sources into content-addressed snapshots and checks CVEs, package versions, or lockfiles offline. The tool prevents stale data or network failures from being misinterpreted as safe.
