Best for
  • Developers on long-running projects using Claude Code, Cursor, Windsurf, or similar tools
  • Teams needing cross-session memory and codebase understanding
  • Developers auditing NPM dependencies within AI workflows
  • Teams performing supply chain security assessments
  • Users of Claude Desktop, Cursor, or VS Code
Not for
  • Users unwilling to index code to a cloud service
  • One-off scripts that need no persistent context
  • 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 a ContextStream API key (secret env var)
  • Reads and indexes project code files
  • Optionally connects GitHub, Slack, and Notion integrations
  • Writes MCP configs, rules, and lifecycle hooks into editor settings
  • 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
  • Indexed code is stored in ContextStream's cloud (vendor states isolation per workspace)
  • A leaked API key could expose workspace data
  • Breaking changes with @modelcontextprotocol/sdk 1.28.0+
  • Hosted HTTP OAuth may be blocked on corporate networks
  • 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
