THE RISK

Why playwright_delete needs a policy

HTTP DELETE requests are used to remove resources on a server. While the actual destructiveness depends on the target endpoint, the DELETE method is semantically and conventionally destructive (irreversible removal of resources). An AI agent misusing this tool could delete arbitrary remote resources, warranting a high severity rating.

From the tool's definition "Perform an HTTP DELETE request" — DELETE is the standard HTTP method for resource deletion

Documented attack patterns abuse exactly the kind of access playwright_delete gives an agent:

POLICY

How to control playwright_delete

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

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "playwright_delete"
  ]
}

playwright_delete 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 Playwright CDP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
