AI agents call get_group_info to retrieve information from Whatsapp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves group information (members, admins, description, creation date) with no side effects or data modification. It is a pure read operation. Severity is medium rather than low because the retrieved information (member lists, admin identities) could be sensitive and reveal organizational structure or relationships if misused by an agent without proper authorization context.
From the tool's definition Tool description states 'Get detailed info for a group: members, admins, description, creation date' - retrieves metadata without modification.
