AI agents call browser_get_console_logs to retrieve information from Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical console log output from a browser session without side effects. It is purely informational retrieval, matching the Read category. Severity is low because console logs typically contain non-sensitive diagnostic information, and misuse would not cause meaningful harm.
