Check our network ERROR logs
AI agents call getNetworkErrors to retrieve information from BrowserTools MCP 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 network error logs from browser monitoring—a read-only operation that passively accesses existing diagnostic data. No side effects, code execution, or data modification occurs. The low severity reflects minimal blast radius: an AI agent misusing this tool could only over-retrieve logs, not alter system state or trigger actions.
From the tool's definition Tool name 'getNetworkErrors' and description 'Check our network ERROR logs' indicate retrieval of logged data with no modification or execution capability.
Attacks that exploit this kind of access
Check our network ERROR logs. It is categorised as a Read tool in the BrowserTools MCP MCP Server, which means it retrieves data without modifying state.
Register the BrowserTools MCP server in PolicyLayer and add a rule for getNetworkErrors: 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 BrowserTools MCP. Nothing to install.
getNetworkErrors 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 getNetworkErrors 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 getNetworkErrors. 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.
getNetworkErrors is provided by the BrowserTools MCP server (sugatraj/cursor-browser-tools-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
