Best for
  • Large local repositories used with AI coding agents.
  • Development teams that need change-impact analysis and safer refactoring.
  • Projects requiring architecture governance, code health metrics, and audit evidence.
  • Users who want local code analysis without API keys.
  • Developers auditing NPM dependencies within AI workflows
  • Teams performing supply chain security assessments
  • Users of Claude Desktop, Cursor, or VS Code
Not for
  • Real-time type checking; the source recommends an LSP for that purpose.
  • Small scripts with fewer than about 10 files.
  • Simple tasks requiring only raw text search.
  • Treating taint or long-tail detector results as complete security coverage.
  • 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 the local repository is needed to discover, parse, and analyze source files.
  • The server creates the local .roam/index.db and related analysis state.
  • Write, persistence, or change-related tools may update .roam control files, run records, or evidence files.
  • API keys and cloud login are not required by default.
  • 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
  • Missing, stale, or interrupted indexes can produce incomplete analysis; inspect returned status and error signals.
  • Static analysis and framework-idiom detection are not substitutes for real-time type checking or deep SAST; some findings are advisory.
  • The full preset exposes 244 tools and may enlarge an agent's prompt surface.
  • The first tree-sitter-language-pack use may download a checksum-verified platform grammar bundle; other network-capable commands and flags are opt-in.
  • Write operations or autonomous-agent modes may create real repository files and run-record changes.
  • 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
