Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

list_addressesList email addressesread-only
This agent's email addresses, and what it is allowed to send.
list_messagesList messagesread-only
The newest messages, newest first, with a short preview of each. Use read_message for the full text.
read_attachmentRead an attachmentread-only
Opens one attachment of a message, by its number in read_message. Text comes back as text and images as images. Anything else, like a PDF, needs save_to: a folder inside the agent's files folder (by default ~/.config/mailcycle/files, or the folders set in MAILCYCLE_FILES_DIR). The file is written there, without overwriting anything, and the path is returned.
read_messageRead a messageread-only
One message in full.
replyReply to a message
Replies to the sender of a message, from the address it was sent to, threaded under it. Works in reply-only mode.
send_messageSend a message
Sends a new message. Needs the agent to be allowed to send to anyone; in reply-only mode use reply instead.
wait_for_messageWait for a messageread-only
Waits for a new message to arrive and returns it in full. Use it right after signing up somewhere to catch a verification code or link. Only mail that arrives after the call starts counts, unless after_message_id is given.
