下载远程服务器的文件或者目录，保存到指定目录下，如果是目录，则递归下载
AI agents call download_file to retrieve information from MCP SSH Tools Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves files from remote servers and saves them locally. It performs no modifications to the source data, no destructive operations, and no code execution—it is purely a read/fetch operation.
From the tool's definition Tool name 'download_file' and description '下载远程服务器的文件或者目录' (download files or directories from remote server) indicates data retrieval without modification of remote state.
Attacks that exploit this kind of access
下载远程服务器的文件或者目录，保存到指定目录下，如果是目录，则递归下载. It is categorised as a Read tool in the MCP SSH Tools Server MCP Server, which means it retrieves data without modifying state.
Register the MCP SSH Tools 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 MCP SSH Tools 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 MCP SSH Tools Server MCP server (nwnusun-cool/mcp-server-ssh-tools). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
