Best for
  • Developers who want to deeply understand Claude Code internals.
  • Developers building plugins or extensions for Claude Code.
  • Researchers interested in Anthropic CLI architecture.
  • Developers auditing NPM dependencies within AI workflows
  • Teams performing supply chain security assessments
  • Users of Claude Desktop, Cursor, or VS Code
Not for
  • Casual users who don't need source code access.
  • Users looking for an officially supported MCP server.
  • Those needing non-stdio transport.
  • 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
  • File system read: needs access to the cloned source directory (set via CLAUDE_CODE_SRC_ROOT env var).
  • Execute searches: may run ripgrep searches within the source directory.
  • 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
  • Source leak: this repo contains leaked source code from Anthropic, usage may carry legal and licensing risks.
  • Security risk: the source may contain unfixed vulnerabilities; use only for research.
  • Instability: non-official project, may lack maintenance.
  • 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
