The first public release - public beta. Expect rough edges; email [email protected] if something breaks.

  • 123 MCP tools across 15 permission domains, served over streamable HTTP on localhost.
  • Mail: IMAP sync with search, plus a triage path (mark read, flag, move, delete, save draft). Write access is off per account until you enable it.
  • Calendar, contacts, and reminders over CalDAV and CardDAV, or the Mac's own Calendar, Contacts, and Reminders.
  • Files: named folder roots you allow, with Markdown and Obsidian-aware editing, Spotlight search, on-device text extraction, media handling, and archive inspection.
  • Cloud storage across S3, R2, B2, FTP, FTPS, SFTP, and WebDAV.
  • SSH command execution against servers you opt in, per account (Pro).
  • Feeds, an HTTP client with saved connection profiles, image generation, outbound mail, notifications, and a Shortcuts runner.
  • Scheduler with cron, interval, and inbound-mail triggers running shell commands, Claude prompts, or prompts against your own AI provider, with run history and a dead-letter queue (Pro).
  • Scoped API keys: one key per agent, scoped by domain, operation, and specific resource (Pro for more than one key).
  • Per-tool kill switches that disable any tool app-wide, for every key.
  • Claude Desktop extension with one-click install from inside the app.
  • First-run setup assistant and an in-app help reference covering 26 topics.
