force_resync · WhatsApp MCP Stream MCP: Risk & Policy

WHAT IT DOES

What force_resync does on WhatsApp MCP Stream

AI agents invoke force_resync to trigger actions in WhatsApp MCP Stream. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why force_resync needs a policy

This tool triggers an external operation that clears application state and forces a reconnection to WhatsApp. While 'clears app state' could suggest destructive behavior, this is a resync/reconnect operation whose primary effect is executing a re-authentication/reconnect cycle rather than irreversibly deleting user data.
