Scan nearby WiFi networks (requires location permission).
AI agents call scan_wifi 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 queries environmental data (available WiFi networks) without creating, modifying, deleting, or executing operations. It is a read-only information gathering function. Severity is low because the information exposed (available WiFi networks) is generally non-sensitive, though location permissions are required. No destructive, financial, or code execution impact.
From the tool's definition Tool performs a scan operation to retrieve nearby WiFi network information. Description states 'Scan nearby WiFi networks' with no mention of modifications, deletions, or side effects beyond data retrieval.
Attacks that exploit this kind of access
Scan nearby WiFi networks (requires location permission). 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 scan_wifi: 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.
scan_wifi 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 scan_wifi 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 scan_wifi. 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.
scan_wifi 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.
