AI agents call get_element_attribute to retrieve information from Mcp Playwright without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information from a web page element's attributes. It performs no side effects, does not modify data, execute code, delete content, or interact with financial systems. It is a pure data retrieval operation, consistent with the Read category. The low severity reflects that misuse would only expose existing page data, not enable harmful actions on the target system.
From the tool's definition Tool name 'get_element_attribute' and description '获取元素属性值' (retrieve element attribute value) indicate a read-only operation that extracts data from DOM elements without modifying page state or executing arbitrary code.

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Playwright, and nothing reaches the server without passing your rules. This is the rule we recommend for get_element_attribute:
{
"version": "1",
"default": "deny",
"tools": {
"get_element_attribute": {}
}
}get_element_attribute is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
