Mailappmcp
Bridges Claude directly to macOS Mail.app via AppleScript, no OAuth or API keys required. Exposes 21 tools covering the full email lifecycle: search and read messages, compose drafts or send immediately, reply with threading, forward and redirect, manage attachments, move between mailboxes, flag and color messages, mark as junk, and trigger manual sync. Works with every account you've configured in Mail.app, whether that's iCloud, Gmail, Outlook, or Fastmail. Particularly useful if you want Claude to triage your inbox, draft replies in your voice, or automate email workflows without leaving your desktop or touching a web API.

macos-mcp
MCP servers for macOS native apps — gives Claude Code, Claude Desktop, and any MCP client native access to Mail, Numbers, Contacts, Calendar, Reminders, and FaceTime / phone calls.
No API keys, no OAuth, no cloud services. Talks directly to macOS apps via AppleScript and URL schemes (tel://, facetime://). Runs locally on your Mac.
CUPS printing (
printmcp) used to live here; it moved to office-mcp since it's a shell wrapper, not an AppleScript bridge.
