Best for
  • Security teams operating under written authorization and defined rules of engagement
  • Red-team researchers and security educators
  • MCP users able to manage a local Node.js environment
  • Developers auditing NPM dependencies within AI workflows
  • Teams performing supply chain security assessments
  • Users of Claude Desktop, Cursor, or VS Code
Not for
  • Targets without explicit written permission
  • Users seeking unrestricted remote scanning or execution
  • Users expecting fully validated end-to-end multi-agent exploitation
  • Projects outside the NPM ecosystem (e.g., pure Python/Go)
  • Environments without network access to deps.dev, OSV.dev, and the npm registry
  • Scenarios requiring maintenance by an official upstream vendor
Required permissions
  • Access to network and security-testing resources within the authorized scope
  • A local Node.js environment, installed dependencies, and any configured agent or model access
  • The supplied material does not specify MCP-client permissions or authentication
  • Network access to the NPM registry and external services (deps.dev, OSV.dev, OpenSSF, npms.io, GitHub)
  • Read access to workspace lockfiles (pnpm-lock.yaml, package-lock., yarn.lock) for cache invalidation
Risks and side effects
  • This is an offensive-security tool and must be used only against owned or explicitly authorized systems
  • Incorrect scoping may cause unauthorized access, data loss, or legal exposure
  • The README says coordinated multi-agent exploitation remains unproven and unreliable
  • External security tools and optional arsenal components may affect targets
  • Third-party READMEs and changelogs are untrusted external content; they are wrapped in tags with _meta flags but should still be handled cautiously
  • Depends on availability and accuracy of external services
  • Batch requests are capped at 25 packages to prevent registry enumeration; larger sets require batching
  • Third-party open source project, not officially maintained by NPM or Anthropic
