WHAT IT DOES

What get_page_errors does on Playwright MCP Server

RISK

Why get_page_errors is rated Low

This tool appears to retrieve or extract error information from a page (likely JavaScript errors, network errors, or console errors) without modifying state. Despite the empty description, the sibling tools on this server (click, evaluate, check_checkbox, apply_antidetect_preset) suggest browser automation capabilities, and get_page_errors fits the read/query pattern of extracting diagnostic data.

From the tool's definition Tool name 'get_page_errors' indicates retrieval of error logs or messages from the page state; no description provided but naming convention strongly suggests a query operation.
