THE RISK

Low Risk

Why xBadTool needs a policy

The description provides no actionable information about the tool's behavior, inputs, or effects. With such an uninformative description, it is impossible to reliably assign a meaningful risk category. Confidence is very low; the tool is classified as 'Other' by default until a proper description is available.

From the tool's definition Tool description is simply 'bad' — completely uninformative about what the tool does.

POLICY

How to control xBadTool

PolicyLayer is an MCP gateway — it sits between your AI agents and Patchwork Os, and nothing reaches the server without passing your rules. This is the rule we recommend for xBadTool:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "xBadTool": {
      "limits": [
        {
          "counter": "xbadtool_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

xBadTool gets a rate cap, and everything else on the server is denied unless you say otherwise.

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