POLICY

How to control browser_screen_capture

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

policy.json

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

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