WHAT IT DOES

What browser_network_request does on Playwright

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs browser_network_request safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Playwright, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For browser_network_request, this is the rule to start with:

browser_network_request Rate-limited

browser_network_request stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
