WHAT IT DOES

What uncheck_checkbox does on Playwright MCP Server

AI agents invoke uncheck_checkbox to trigger actions in Playwright MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why uncheck_checkbox is rated High

Based on the server context (Playwright browser automation) and the tool name, this tool interacts with a browser's DOM by unchecking a checkbox element. This is a browser action/execute operation. The description is empty, which lowers confidence, but the name and sibling tools (click, check_checkbox, clear_text) clearly indicate UI interaction/execution.

From the tool's definition Tool name 'uncheck_checkbox' on a Playwright browser automation server that performs DOM manipulation and webpage interaction.
