Get browser console errors
AI agents call get_console_errors to retrieve information from Chromium ARM64 Browser without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves diagnostic information from the browser console. It performs a read-only query of already-generated error logs. There are no side effects, data modification, code execution triggered by the tool itself, or destructive operations. Even in a misuse scenario, an agent obtaining console error logs cannot cause harm beyond information disclosure, which is a low-severity read operation.
From the tool's definition Tool name is 'get_console_errors' and description states 'Get browser console errors' — a retrieval operation with no side effects. It queries existing console state without modifying browser state or data.
Attacks that exploit this kind of access
Get browser console errors. It is categorised as a Read tool in the Chromium ARM64 Browser MCP Server, which means it retrieves data without modifying state.
Register the Chromium ARM64 Browser MCP server in PolicyLayer and add a rule for get_console_errors: 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 Chromium ARM64 Browser. Nothing to install.
get_console_errors 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 get_console_errors 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 get_console_errors. 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.
get_console_errors is provided by the Chromium ARM64 Browser MCP server (nfodor/mcp-chromium-arm64). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
get_console_errors is one line of Chromium ARM64 Browser's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
