Description

list_received_messages(limit=20)

Summaries of received messages, most recent first

list_sent_messages(limit=20)

Summaries of sent messages, most recent first

get_message(message_id, include_attachment_content=False)

Full message with documents; attachment bytes are base64-encoded and only included on request

mark_message_read(message_id)

Mark a received message as read

send_message(recipient_box_id, subject, attachments, ...)

Send a new message; attachments is a list of {filename, mime_type, content_base64, is_main} dicts, exactly one of which must be is_main=True

send_text_message(recipient_box_id, subject, body)

Compose plain text as a PDF and send it as the message's main document — no existing file needed

find_data_box(query, limit=10)

Look up a recipient's data box ID by name, trade name, or IČO. Uses the offline seznamds directory first (fast, unlimited), falling back to the live, rate-limited ISDS search API if it's absent or finds nothing. The response includes source and data_age_days so a stale offline snapshot doesn't get presented as current.
