Best for
  • Users who want a real-time view of disk space distribution.
  • Users who want AI-assisted disk cleanup and data management.
  • Users needing a cross-platform (macOS, Windows, Linux) storage analyzer.
  • Local assistants that need to work inside explicitly approved directories
  • Individuals and development teams that want path-based data boundaries
Not for
  • Users who need permanent deletion (rather than moving to trash).
  • Users who need content-level cloud scanning (metadata only).
  • Users who cannot install Node.js for MCP usage.
  • Highly sensitive environments that cannot allow model access to local file contents
  • Shared remote file-service use cases
Required permissions
  • Read file and folder metadata (size, path, etc.).
  • Move files to the system trash (via OS APIs, recoverable).
  • Access system trash size.
  • Optionally listen on the LAN in a separate process (Fleet feature, off by default).
  • Read access to every local directory listed in the configuration
  • Filesystem write access when write or move tools are enabled
Risks and side effects
  • AI might accidentally trash important files, but deletions go to the system trash and can be manually restored.
  • AI may scan folders with sensitive information, but data is processed locally and not uploaded.
  • Cloud interactions are metadata-only; no file contents are downloaded.
  • Offload requires sufficient space on the target drive; failure rolls back safely.
  • Sensitive files inside an allowed directory may enter model context
  • Write and move tools change real files; keep scopes narrow and maintain backups
