WHAT IT DOES

What generate_wifi_qr does on Enhanced QR Code MCP Server

AI agents use generate_wifi_qr to create or update resources in Enhanced QR Code MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Enhanced QR Code MCP Server environment.

WHY IT NEEDS A POLICY

Why generate_wifi_qr needs a policy

This tool creates new data (a QR code image/file) that encodes WiFi network information. It does not execute code, delete data, move money, or trigger external side effects—it simply generates a static encoded image. While the encoded WiFi credentials are sensitive, the tool itself only produces a reversible artifact (the QR code file can be deleted or regenerated).

From the tool's definition Tool generates QR codes encoding WiFi credentials (SSID, password, security type). The description states it 'Generate[s] a QR code for WiFi network credentials,' which is data creation. The QR code itself is a new artifact created and stored.
