What browser_network_state_set does on Playwright
AI agents invoke browser_network_state_set to trigger actions in Playwright. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why browser_network_state_set is rated High
The tool name suggests it modifies browser network state (e.g., simulating offline mode, throttling, intercepting requests). This is an Execute-level action as it affects browser networking behavior and can influence how web pages operate. Confidence is reduced due to empty description, but the 'set' operation on network state in a browser automation context implies side effects beyond simple reads or writes.
From the tool's definition Tool name 'browser_network_state_set' and empty description; inferred from name pattern in a browser automation MCP server context.
Attacks that exploit this kind of access
The rule that runs browser_network_state_set 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_state_set, this is the rule to start with:
browser_network_state_set 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Playwright, apply this rule, and every browser_network_state_set call is checked against it from then on.
