Best for
  • OPC UA integration in industrial control, manufacturing, energy, and IoT systems
  • Developers who need AI assistants to access OPC UA client operations
  • Teams building OPC UA tools or applications on .NET
  • Developers auditing NPM dependencies within AI workflows
  • Teams performing supply chain security assessments
  • Users of Claude Desktop, Cursor, or VS Code
Not for
  • Applications that do not use OPC UA
  • Deployments requiring documented tool identifiers or client configuration not present in the source
  • Environments requiring transport, authentication, or authorization details that the source does not specify
  • 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 the target OPC UA server
  • Read/write, method-call, and subscription operations require the corresponding permissions granted by the target OPC UA server; the precise permission model is not specified
  • 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
  • Writing values or calling methods may change industrial-system or device state
  • Subscriptions and diagnostics may maintain connections or consume additional resources
  • The source does not specify authentication, authorization, or transport configuration; verify the target environment's security requirements before deployment
  • Repository metadata is NOASSERTION, while the project README and server manifest state MIT; confirm the applicable license before adoption
  • 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
