THE RISK

Low Risk

Why take-screenshot needs a policy

Taking a screenshot is fundamentally a read operation: it queries the current visual state of the Android device. While the result is saved locally, there are no side effects on the device, no data modification, no code execution, and no destructive actions.

From the tool's definition Tool description states it 'capture[s] device screenshot' – a read operation that retrieves visual data from the device without modifying state.

POLICY

How to control take-screenshot

PolicyLayer is an MCP gateway — it sits between your AI agents and Android Mcp Toolkit, and nothing reaches the server without passing your rules. This is the rule we recommend for take-screenshot:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "take-screenshot": {}
  }
}

take-screenshot is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Android Mcp Toolkit — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I block take-screenshot completely? +

Set action: deny in the PolicyLayer policy for take-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.

What MCP server provides take-screenshot? +

take-screenshot is provided by the Android Mcp Toolkit MCP server (nam0101/android-mcp-toolkit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Android Mcp Toolkit tool call.

Start from Android Mcp Toolkit, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
