Best for
  • Developers building MCP clients or AI applications that need search functionality
  • Use cases requiring simultaneous queries of multiple search terms
  • Users wanting to use a custom or public SearXNG instance
  • Developers auditing NPM dependencies within AI workflows
  • Teams performing supply chain security assessments
  • Users of Claude Desktop, Cursor, or VS Code
Not for
  • Scenarios requiring browser automation or dynamic rendering of results
  • Production environments needing official support or commercial guarantees
  • Users with strict requirements for search API stability and maintenance
  • 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 SearXNG API, requiring a valid SEARXNG_URL
  • USERNAME and PASSWORD if SearXNG uses Basic Auth
  • Network access to communicate with the SearXNG server
  • 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
  • Dependency on external SearXNG service, may be affected by network or service availability
  • No official support, with no guarantee of security or stability
  • Privacy risks when using public SearXNG instances, as queries may be logged
  • 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
