What clear_text does on Playwright MCP Server
AI agents invoke clear_text 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.
Why clear_text is rated High
Given the server context (Playwright browser automation with DOM manipulation capabilities) and sibling tools like 'click', 'check_checkbox', and 'evaluate', 'clear_text' most likely clears text from an input field or text area in the browser — a browser action/DOM manipulation. This falls under Execute as it triggers an external browser operation. Confidence is reduced due to the empty description.
From the tool's definition Tool name 'clear_text' on a Playwright browser automation server; description is empty and uninformative.
Attacks that exploit this kind of access
The rule that runs clear_text safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Playwright MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For clear_text, this is the rule to start with:
clear_text stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Playwright MCP Server, apply this rule, and every clear_text call is checked against it from then on.
