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

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

## Why local_users is rated Low

This is a read-only operation that enumerates system user and group accounts. While it retrieves sensitive system information (user account enumeration) that could enable privilege escalation or lateral movement planning, the tool itself performs no destructive, write, or execute operations.

From the tool's own definition: "Tool name is 'local_users' and description states 'List local users/groups' — it retrieves and queries user/group information without modifying or deleting data."

## Use case

AI agents call local_users 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.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Claude C2:

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