browser_network_requests
AI agents call browser_network_requests to retrieve information from Playwright MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name suggests it retrieves/lists network requests made by the browser, which is a read operation. However, the empty description lowers confidence. Network request data could expose sensitive information (auth tokens, cookies, API keys), hence medium severity. Classifying as Read since 'network_requests' implies fetching/querying captured request data rather than initiating or modifying requests.

Register the Playwright MCP server in PolicyLayer and add a rule for browser_network_requests: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Playwright MCP. Nothing to install.
browser_network_requests is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the browser_network_requests rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for browser_network_requests. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
browser_network_requests is provided by the Playwright MCP server (lysander72/playwright-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
