clear-element

THE RISK

Critical Risk

An AI agent that decides to call clear-element doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from MCP Appium Server is gone — there is no undo for destructive operations.

Documented attack patterns abuse exactly the kind of access clear-element gives an agent:

HOW TO CONTROL CLEAR-ELEMENT

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Appium Server, and nothing reaches the server without passing your rules. This is the rule we recommend for clear-element:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "clear-element"
  ]
}

clear-element disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

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