Service Constants

Provider-specific settings live in src/mcp_email_webdav_caldav/constants.py:

• Email IMAP/SMTP host, port, SSL, sent-folder, and attachment-download settings.
• WebDAV account name, base URL, description, SSL verification, download, and upload settings.
• CalDAV account name, base URL, description, SSL verification, and write settings.

Email, WebDAV, and CalDAV accounts can also be saved to ~/.config/zerolib/mcp_email_webdav_caldav/config.json via the add_email_account, add_webdav_account, and add_caldav_account tools. Override the file location with MCP_EMAIL_WEBDAV_CALDAV_CONFIG_PATH.

list_emails_metadata returns mailbox together with each email_id; pass the same mailbox to get_emails_content, delete_emails, and download_attachment. Set all_mailboxes=true to search every selectable IMAP folder.

webdav_download_file and webdav_upload_file are disabled by default because they read/write local files. Enable them explicitly in constants.py.

caldav_put_event, caldav_create_event, and caldav_delete_event are disabled by default because they modify remote calendars. Enable them explicitly in constants.py.
