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

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

## Why execute_bof is rated High

This tool executes arbitrary compiled code (BOF - Beacon Object File) on a remote compromised host through a Cobalt Strike beacon. This is a code execution capability whose effects are determined by the BOF payload arguments and can range from reconnaissance (whoami) to privilege escalation, lateral movement, or data exfiltration.

From the tool's own definition: "Tool name 'execute_bof' and description 'Execute a BOF (Beacon Object File) on a beacon' explicitly indicates execution of compiled code on a compromised target system."

## Use case

AI agents invoke execute_bof 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:
