WHAT IT DOES

What switch_page does on Playwright MCP Server

AI agents invoke switch_page 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 switch_page is rated High

This tool exists on a Playwright MCP server that performs browser automation (webpage interaction, DOM manipulation). 'switch_page' likely switches the active browser page/tab context, which is an Execute-level browser action. However, the description is empty, so confidence is reduced.

From the tool's definition Tool name 'switch_page' on a Playwright browser automation server; description is empty and uninformative.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

switch_page Rate-limited

switch_page 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.
