AI agents call whatsapp_account_info to retrieve information from Waha without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves account information without modifying, deleting, executing code, or moving money. It is purely informational—used to verify which account is connected. The severity is low because disclosure of one's own account metadata poses minimal risk in the context of an already-authenticated session.
From the tool's definition Tool description states 'Get information about the authenticated WhatsApp account' and 'Returns the phone number, display name, and WhatsApp ID'. The verb 'Get' and the passive retrieval of account metadata indicate a read-only operation with no side effects.
