Download a specific file or URL. Simpler than clone_website,
AI agents call download_file to retrieve information from WebClone MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves/fetches file content without creating, modifying, or deleting data. However, severity is medium rather than low because the server context indicates it can manage authentication sessions and access potentially sensitive content, and a compromised AI agent could download confidential files, credentials, or private data if given malicious URLs or file paths.
From the tool's definition Tool name 'download_file' and description state it 'Download a specific file or URL' with no modification, deletion, or execution capabilities mentioned.
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 WebClone MCP Server, 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.

Download a specific file or URL. Simpler than clone_website,. It is categorised as a Read tool in the WebClone MCP Server MCP Server, which means it retrieves data without modifying state.
Register the WebClone MCP Server 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 WebClone MCP Server. 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 WebClone MCP Server MCP server (ruslanmv/webclone). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from WebClone MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
