What the publisher says

From the Numbersmcp repository's README, as published. We do not edit it. Read it on GitHub

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.
