List all available sensors on the device.
AI agents call get_sensor_list 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 retrieves and enumerates available sensors without creating, modifying, deleting, or executing any operations. It is a passive information retrieval operation with no side effects or ability to alter device state. The blast radius of misuse is minimal—an agent could only learn what sensors exist, not control them or access their data. Severity is low due to the benign nature of sensor enumeration.
From the tool's definition Tool name is 'get_sensor_list' and description states 'List all available sensors on the device.' The verb 'list' and action of retrieving sensor information with no modification capability indicates a read-only query operation.
Attacks that exploit this kind of access
List all available sensors on the device. 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 get_sensor_list: 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.
get_sensor_list 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 get_sensor_list 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 get_sensor_list. 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.
get_sensor_list 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.
get_sensor_list 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.
