WHAT IT DOES

What download does on Claude C2

AI agents call download to retrieve information from Claude C2 without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why download is rated Low

While the download operation itself is technically a Read action (retrieving files without modifying them), the severity is high because: (1) it operates within a C2 framework designed for unauthorized access, (2) it can exfiltrate sensitive files from compromised systems, (3) the automatic client selection increases risk of unintended data theft, and (4) in a C2 context, any file download likely involves…

RECOMMENDED RULE

The rule that runs download safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Claude C2, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For download, this is the rule to start with:

download Allowed

download is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "download": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Claude C2, apply this rule, and every download call is checked against it from then on.
