WHAT IT DOES

What type_text does on Playwright MCP Server

AI agents invoke type_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.

RISK

Why type_text is rated High

On a Playwright automation server, 'type_text' almost certainly simulates keyboard input into browser elements (forms, inputs, etc.). This is a browser action/execute-level capability that could be used to submit forms, enter credentials, trigger JavaScript events, or interact with web applications in ways whose effects depend on arguments.

From the tool's definition Tool name 'type_text' on a Playwright browser automation server that exposes 'webpage interaction, DOM manipulation' capabilities; sibling tools include 'click', 'evaluate', 'clear_text' confirming interactive browser control

RECOMMENDED RULE

The rule that runs type_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 type_text, this is the rule to start with:

type_text Rate-limited

type_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.
