Get details for a captured network request (optionally includes response body).
AI agents call browser.get_network_request to retrieve information from MCP Playwright Browser without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries captured network request metadata and optionally response bodies—purely informational side effects. However, severity is elevated to medium rather than low because response bodies may contain sensitive data (API keys, tokens, PII, credentials) that could be exfiltrated if an agent is compromised, creating indirect risk despite the tool itself performing no destructive or financial…

Register the MCP Playwright Browser MCP server in PolicyLayer and add a rule for browser.get_network_request: 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 MCP Playwright Browser. Nothing to install.
browser.get_network_request 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.get_network_request 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.get_network_request. 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.
