WHAT IT DOES

What download_payload does on Cobalt Strike MCP Server

AI agents call download_payload to retrieve information from Cobalt Strike MCP Server 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_payload is rated Low

The tool downloads (fetches) a payload file that has already been generated. The action itself is a read operation (no side effects on the server), but the blast radius is high because the downloaded artifact is a Cobalt Strike payload — malicious software used in red team (and potentially malicious) operations. Misuse by an AI agent could facilitate delivering offensive payloads.

From the tool's definition 'Download a generated payload file' — this retrieves/downloads an already-generated payload file, which is a read/fetch operation

RECOMMENDED RULE

The rule that runs download_payload safely

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

download_payload Allowed

download_payload 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_payload": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect Cobalt Strike MCP Server, apply this rule, and every download_payload call is checked against it from then on.
