| Best for | - Developers using one of the supported AI coding CLIs, IDEs, or agents
- Teams working with large codebases, logs, web pages, or batch queries
- Users who need work-state recovery after context compaction
| - Developers auditing NPM dependencies within AI workflows
- Teams performing supply chain security assessments
- Users of Claude Desktop, Cursor, or VS Code
|
|---|
| Not for | - Users requiring a dedicated GUI MCP integration not listed as supported
- Users who only need a simple MCP tool and do not want hooks, plugins, or local indexing
- Environments that prohibit local script execution or access to local files, credentials, and network resources
| - 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 Node.js, Bun, or another listed runtime to execute locally.
- Sandboxed scripts can read and process local files and can use authenticated CLIs such as gh, aws, gcloud, kubectl, and docker through inherited environment variables and configuration paths.
- ctx_fetch_and_index requires URL fetching; indexed content is stored in SQLite databases under the user's local data directory.
- With hooks or plugins enabled, the server can intercept selected tool calls, record session events, and apply routing rules.
| - 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 | - Tools such as ctx_execute run code supplied by the user or agent; that code may read local files, invoke commands, or use inherited credentials.
- Session and indexed content persist in local SQLite databases; ctx_purge permanently deletes all indexed content.
- Hooks may block or redirect selected tool calls, and routing capabilities vary by client.
- The README's savings percentages are project-reported metrics; actual results depend on tool output and usage.
| - 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
