## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "spawn_command_runNoOutput",
    "arguments": {}
  }

```

## Why spawn_command_runNoOutput is rated High

This tool executes arbitrary commands on remote beacons without returning output, enabling attackers to run malicious payloads silently. In the context of Cobalt Strike (a commercial adversarial simulation framework), this represents remote code execution with no observability constraints.

From the tool's own definition: "Tool name includes 'spawn_command' and description states 'Run command without output'. The Cobalt Strike MCP Server explicitly provides 'beacon control' and 'payload generation' for 'red team operations'."

## Use case

AI agents invoke spawn_command_runNoOutput to trigger actions in Cobalt Strike MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Cobalt Strike MCP Server:

```json
