WHAT IT DOES

What list_mail_accounts does on AIquila — Nextcloud MCP Server

AI agents call list_mail_accounts to retrieve information from AIquila — Nextcloud MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_mail_accounts is rated Low

This tool queries and returns email account configuration data from Nextcloud Mail. It performs read-only information retrieval. Severity is medium rather than low because exposed email account details (account IDs, names, addresses) could enable further attacks or social engineering if an AI agent retrieves this information without authorization.

From the tool's definition Tool name and description explicitly state 'List all configured email accounts' and 'Returns account IDs, names, and email addresses'. This is a retrieval operation with no side effects.
