获取当前标签页的DOM树结构信息 Args: depth (int): 指定获取DOM树的深度 Returns: str: 返回DOM树的JSON结构数据
AI agents call get_dom_tree to retrieve information from DrissionPageMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries the DOM tree structure of a webpage without modifying, executing code, or triggering external operations. It is a read-only information retrieval operation with no side effects. Even though it operates within a browser automation context, the specific function is passive data retrieval, making it a Read category tool with low severity.
From the tool's definition Tool name 'get_dom_tree' and description '获取当前标签页的DOM树结构信息' (get DOM tree structure information from current tab) with return value of 'DOM树的JSON结构数据' (DOM tree JSON structure data). The args include only 'depth' parameter for controlling retrieval depth.
Documented attack patterns abuse exactly the kind of access get_dom_tree gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and DrissionPageMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_dom_tree:
{
"version": "1",
"default": "deny",
"tools": {
"get_dom_tree": {}
}
}get_dom_tree is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

获取当前标签页的DOM树结构信息 Args: depth (int): 指定获取DOM树的深度 Returns: str: 返回DOM树的JSON结构数据. It is categorised as a Read tool in the DrissionPageMCP MCP Server, which means it retrieves data without modifying state.
Register the DrissionPage MCP server in PolicyLayer and add a rule for get_dom_tree: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches DrissionPageMCP. Nothing to install.
get_dom_tree is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_dom_tree rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_dom_tree. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_dom_tree is provided by the DrissionPage MCP server (wxhzhwxhzh/drissionpagemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
