This MCP server:

• Runs locally on your machine
• Uses the numbers-parser Python library to read/write .numbers files, and AppleScript to drive Numbers.app for formatting and formulas
• Saves file modifications atomically (temp file + os.replace) so an interrupted write cannot corrupt the target file
• Does not transmit data to external servers
• Does not store credentials or passwords

The formatting/formula tools require macOS automation permission for Numbers.app. These permissions are managed by macOS and can be revoked at any time in System Settings → Privacy & Security → Automation.
