WHAT IT DOES

What whatsapp_create_group does on WSAPI WhatsApp MCP Server

WHY IT NEEDS A POLICY

Why whatsapp_create_group needs a policy

Creating a WhatsApp group is a reversible write operation that modifies user data and social structure but does not delete data irreversibly or execute arbitrary code. The impact is medium severity because an AI agent could create unwanted groups that clutter a user's account, impact their social relationships, or enable spam/harassment, but the action can be undone by deleting the group.

From the tool's definition Tool name 'whatsapp_create_group' and description 'Create a new WhatsApp group' indicate creation of a new resource (group). The server description confirms this enables 'group operations' through the WSAPI service.
