Best for
  • Security teams needing to ensure the security of MCP servers.
  • Developers checking for vulnerabilities in MCP servers before deployment.
  • Organizations looking to integrate security scanning into CI/CD pipelines.
  • Developers auditing NPM dependencies within AI workflows
  • Teams performing supply chain security assessments
  • Users of Claude Desktop, Cursor, or VS Code
Not for
  • People looking for an MCP server implementation or client.
  • Users needing real-time monitoring or active defense solutions.
  • Organizations with strict privacy requirements regarding commercial APIs or external services.
  • 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
  • Requires access to Cisco AI Defense API key (optional).
  • Requires an LLM provider API key (optional, for LLM analyzer).
  • Requires a VirusTotal API key (optional, for malware scanning).
  • 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
  • Relies on external API services, which may raise data privacy concerns.
  • Scanning may produce false positives or negatives.
  • Requires proper configuration of environment variables; otherwise, may fail to run.
  • 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
Supported clientsClaude Desktop, VS Code, Cursor
