Best for
  • Developers using JetBrains IDEs who want AI-assisted development
  • Teams that have JetBrains IDEs installed and need AI assistant integration
  • Developers auditing NPM dependencies within AI workflows
  • Teams performing supply chain security assessments
  • Users of Claude Desktop, Cursor, or VS Code
Not for
  • Developers not using JetBrains IDEs
  • Users needing long-term support or latest features (since deprecated, use built-in IDE functionality)
  • 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
  • Needs access to the local port of JetBrains IDE (default 127.0.0.1:6365)
  • Requires running npx, so Node.js 18 or later must be installed
  • 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
  • Deprecated and no longer maintained, potential unpatched security vulnerabilities or compatibility issues
  • Requires correct IDE port and host configuration, otherwise connection fails
  • External connections may be needed for third-party clients, posing security risks
  • 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
