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

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

## Why list_files is rated Low

This tool retrieves and queries file metadata from a system. It performs no writes, deletes, executions, or financial operations. However, severity is rated 'medium' rather than 'low' because file metadata listings can reveal sensitive information (file names, sizes, timestamps, paths) that an AI agent could use for reconnaissance, information disclosure, or to identify targets for further attacks.

From the tool's own definition: "Tool name and description: 'list_files' — 'List all uploaded files with metadata.' The verb 'list' and 'get' metadata are quintessential read operations that retrieve information without modification."

## Use case

AI agents call list_files to retrieve information from Agent Jail 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 Agent Jail:

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