Take a screenshot of the current display for a given box.
AI agents call get_screenshot to retrieve information from Android Tester MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Screenshots are read-only operations that capture current state without side effects. While screenshots could theoretically expose sensitive information displayed on screen, the tool itself performs no destructive, executable, or financial operations. The risk is informational leakage rather than active harm, making it a Read category tool at low severity.
From the tool's definition Tool name 'get_screenshot' and description 'Take a screenshot of the current display' indicate retrieval of visual data with no modification, creation, deletion, or code execution.
Attacks that exploit this kind of access
Take a screenshot of the current display for a given box. It is categorised as a Read tool in the Android Tester MCP MCP Server, which means it retrieves data without modifying state.
Register the Android Tester MCP server in PolicyLayer and add a rule for get_screenshot: 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 Tester MCP. Nothing to install.
get_screenshot 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_screenshot 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_screenshot. 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_screenshot is provided by the Android Tester MCP server (zhenweiwang1990/android-tester-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
