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

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

## Why list_beacons is rated Low

This tool retrieves information about active beacons without modifying, executing code on, or deleting them. It is purely informational. However, the severity is rated 'high' because Cobalt Strike is a commercial red team command-and-control framework, and access to beacon inventory reveals the scope and state of an active red team operation—critical intelligence if misused by an unauthorized agent.

From the tool's own definition: "Tool name 'list_beacons' and description 'List all active beacons in the Cobalt Strike teamserver' indicate a query/retrieval operation with no side effects."

## Use case

AI agents call list_beacons 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.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_beacons": {}
  }
}
```
