WHAT IT DOES

What file_copy does on Aapanel

AI agents use file_copy to create or update resources in Aapanel, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Aapanel environment.

RISK

Why file_copy is rated Medium

File copying is a reversible write operation that creates new data without permanently destroying existing data. However, it poses high severity risk because an AI agent could maliciously copy sensitive files (credentials, private keys, databases) to accessible locations, exfiltrate them, or create space exhaustion attacks.

From the tool's definition Tool name 'file_copy' and description 'Copy a file/directory' indicate the creation of new file data by duplicating existing files or directories.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs file_copy safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Aapanel, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For file_copy, this is the rule to start with:

file_copy Rate-limited

file_copy stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
