Capture the Android device screen as a screenshot.
AI agents call adb_screenshot to retrieve information from Claude Pascal 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 visual information from an Android device without creating, modifying, deleting, or executing operations. Screenshots are read-only queries of the device state. While the tool could reveal sensitive information displayed on screen, the severity remains low because the capability is non-destructive and limited to observation. The confidence is high given the clear, unambiguous function description.
From the tool's definition Tool name 'adb_screenshot' and description 'Capture the Android device screen as a screenshot' indicate data retrieval with no modification or destructive capability.
Documented attack patterns abuse exactly the kind of access adb_screenshot gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Claude Pascal MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for adb_screenshot:
{
"version": "1",
"default": "deny",
"tools": {
"adb_screenshot": {}
}
}adb_screenshot is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Capture the Android device screen as a screenshot. It is categorised as a Read tool in the Claude Pascal MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Claude Pascal MCP Server MCP server in PolicyLayer and add a rule for adb_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 Claude Pascal MCP Server. Nothing to install.
adb_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 adb_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 adb_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.
adb_screenshot is provided by the Claude Pascal MCP Server MCP server (tina4stack/claude-pascal-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Claude Pascal MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
