Download files from the Daytona workspace with smart handling for different file types and sizes. Supports text, binary, images, PDFs, and other formats with automatic content type detection. Results can be returned as text, base64-encoded data, or embedded resources.
AI agents call file_download to retrieve information from Daytona MCP Python Interpreter without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
file_download retrieves or queries data from the workspace without side effects. It does not create, modify, delete, or execute anything—it only fetches and returns existing files in various formats. This is a classic Read operation with minimal risk; misuse would only expose data already in the workspace.
From the tool's definition Tool description states it 'Download files from the Daytona workspace' with support for 'text, binary, images, PDFs, and other formats' and specifies results are returned 'as text, base64-encoded data, or embedded resources.' The verb 'download' and the…
Documented attack patterns abuse exactly the kind of access file_download gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Daytona MCP Python Interpreter, and nothing reaches the server without passing your rules. This is the rule we recommend for file_download:
{
"version": "1",
"default": "deny",
"tools": {
"file_download": {}
}
}file_download is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Download files from the Daytona workspace with smart handling for different file types and sizes. Supports text, binary, images, PDFs, and other formats with automatic content type detection. Results can be returned as text, base64-encoded data, or embedded resources. It is categorised as a Read tool in the Daytona MCP Python Interpreter MCP Server, which means it retrieves data without modifying state.
Register the Daytona MCP Python Interpreter MCP server in PolicyLayer and add a rule for file_download: 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 Daytona MCP Python Interpreter. Nothing to install.
file_download 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 file_download 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 file_download. 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.
file_download is provided by the Daytona MCP Python Interpreter MCP server (nibzard/daytona-mcp-interpreter). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Daytona MCP Python Interpreter, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
