This code can reach further than it looks
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

}This one needs environment variables set before it will start:
APPLE_CALENDAR_MCP_SAFETY_MODE (Safety mode for Calendar operations: safe_readonly, safe_manage, or full_access.), APPLE_CALENDAR_MCP_ALLOWED_CALENDARS (Comma-separated allow-list of calendar names. Empty allows all calendars.), APPLE_CALENDAR_MCP_WRITE_ALLOWED_CALENDARS (Comma-separated allow-list of calendar names that may be written to (create/update/delete). Reads are unaffected, so a client can see every calendar while only being able to modify these. Empty applies no write-specific restriction.).
