## Why wa_disconnect_instance is rated High

This tool triggers an external operation — disconnecting a WhatsApp instance — which affects its connectivity state. It is not purely destructive since the session is preserved for reconnection, but it does execute an action that interrupts service. Misuse could cause an AI agent to disconnect active WhatsApp sessions, disrupting communication.

From the tool's own definition: "Gracefully disconnect a WhatsApp instance. The session is preserved for reconnection."

## Use case

AI agents invoke wa_disconnect_instance to trigger actions in WA MCP. 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.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches WA MCP:
