Click an element in an iframe on the page
AI agents invoke playwright_iframe_click 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.
Clicking elements in a browser iframe is an Execute-category action because it triggers real browser interactions whose effects are entirely dependent on the target element and context — could submit forms, trigger purchases, navigate pages, or activate arbitrary JavaScript handlers. Iframes often embed third-party content (payment widgets, OAuth flows), raising the severity to high.
From the tool's definition 'Click an element in an iframe on the page' — triggers a browser click action inside an iframe, causing side effects that depend on what the element does (form submission, navigation, UI state changes, etc.)
Documented attack patterns abuse exactly the kind of access playwright_iframe_click gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Playwright MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for playwright_iframe_click:
{
"version": "1",
"default": "deny",
"tools": {
"playwright_iframe_click": {
"limits": [
{
"counter": "playwright_iframe_click_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}playwright_iframe_click 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.
