THE RISK

Why playwright_get needs a policy

An HTTP GET request is a read operation that retrieves data without modifying server state. It has no side effects by HTTP specification. Low severity as it only fetches data, though it could be used to retrieve sensitive information.

POLICY

How to control playwright_get

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_get:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "playwright_get": {}
  }
}

playwright_get 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 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.
