AI agents call download_file 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.
Even though download_file only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Documented attack patterns abuse exactly the kind of access download_file 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 download_file:
{
"version": "1",
"default": "deny",
"tools": {
"download_file": {}
}
}download_file is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

下载文件到指定路径 Args: url (str): 文件的URL地址 path (str): 文件保存的路径 rename (str, optional): 重命名文件名. Returns: str: 下载结果信息. 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 download_file: 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.
download_file 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 download_file 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 download_file. 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.
download_file 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.
