What You'll Need

Set these up before or after installing:

Register the mutating tools. Off by default, and the gate decides whether the write tools exist at all rather than merely refusing — an agent with writes off cannot see them.Optional

Environment variable: APPLE_MAIL_ALLOW_WRITES

Restrict every read and write to these Mail accounts, by name. Bounds reading, not just writing.Optional

Environment variable: APPLE_MAIL_ACCOUNTS

Let the compose tools attach a local file and send in the same call. Attaching to a draft needs only writes; this is off by default because an immediate send puts the file in someone's inbox with nobody reviewing it.Optional

Environment variable: APPLE_MAIL_ALLOW_FILE_SEND
