Generate a WiFi QR code string (WIFI:S:<SSID>;T:<type>;P:<password>;;).
AI agents call wifi_qr_code to retrieve information from Android MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool produces a formatted text string representation of WiFi credentials. It has no side effects: it does not connect to networks, modify device settings, execute commands, delete data, or move money. The output is a passive data structure suitable for display or encoding into visual QR codes.
From the tool's definition Tool 'wifi_qr_code' generates a QR code string in standard WiFi format (WIFI:S:<SSID>;T:<type>;P:<password>;;).
Attacks that exploit this kind of access
Generate a WiFi QR code string (WIFI:S:<SSID>;T:<type>;P:<password>;;). It is categorised as a Read tool in the Android MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Android MCP Server MCP server in PolicyLayer and add a rule for wifi_qr_code: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Android MCP Server. Nothing to install.
wifi_qr_code is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the wifi_qr_code rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for wifi_qr_code. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
wifi_qr_code is provided by the Android MCP Server MCP server (wujie272/android-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
wifi_qr_code is one line of Android MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
