    deploy to koyeb

    The form opens with CHANGE_ME for each value you supply: IMAP_HOST, IMAP_USER, IMAP_PASSWORD, IMAP_PORT, IMAP_TLS, IMAP_MAILBOX, IMAP_SEEN_KEYWORD, IMAP_READ_ONLY, IMAP_ALLOW_TOOLS, IMAP_DENY_TOOLS, IMAP_DOWNLOAD_DIR, IMAP_INSECURE_TLS, IMAP_DRAFTS_MAILBOX, IMAP_MAX_MESSAGES, IMAP_MAX_ATTACHMENT_BYTES, IMAP_MAX_DOWNLOAD_BYTES, IMAP_MAX_EXTRACT_BYTES, IMAP_ATTACHMENT_TYPES, IMAP_TRUSTED_AUTHSERV_ID. Fill them in before you deploy.

    Clients connect to the service's https://…koyeb.app address plus /mcp.
