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

```json
{
  "jsonrpc": "2.0",

  "method": "tools/call",
  "params": {
    "name": "list_directory",
    "arguments": {}

## Why list_directory is rated Low

This tool queries and retrieves directory structure information without modifying, executing, or deleting anything. It is a read-only operation that simply presents existing filesystem metadata in a formatted view. The low severity reflects minimal blast radius if misused—an AI agent listing directories cannot cause data loss or execute arbitrary code.

From the tool's own definition: "Tool name 'list_directory' and description 'List the contents of a directory within the project in a tree-like format' indicate data retrieval with no side effects."

## Use case

AI agents call list_directory to retrieve information from Code 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 Code:

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

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
