Best for
  • Developers and DevOps teams looking to manage self-hosted infrastructure via CLI or AI agents
  • Users who want to streamline server provisioning and hardening across multiple cloud providers
  • Teams that want to integrate security audits into CI/CD pipelines
  • Developers auditing NPM dependencies within AI workflows
  • Teams performing supply chain security assessments
  • Users of Claude Desktop, Cursor, or VS Code
Not for
  • People without SSH access or who do not need cloud provider integrations
  • Users who require a GUI or managed service rather than a CLI
  • Those who need macOS/BSD support (Linux only platform)
  • Those who need full Windows native support (manages Linux servers only via SSH)
  • 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 access to cloud provider API tokens (Hetzner, DigitalOcean, Vultr, Linode)
  • Requires SSH access to target servers to perform audits, hardening, and maintenance
  • Can create SSH keys and configuration files on the local machine
  • Can execute destructive operations on servers (if enabled)
  • 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
  • Destructive operations (destroy, restore, snapshot-delete, provision, restart, maintain, snapshot-create) are blocked in default safe mode; if enabled, risk of data loss
  • API tokens are sensitive; ensure they are stored securely
  • SSH connections may be intercepted; use strict host key verification
  • Automated operations may inadvertently change server configurations
  • Misuse could lead to service disruption or security vulnerabilities
  • 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
