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

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

## Why list_libraries is rated Low

This is a straightforward informational lookup tool that queries documentation coverage for libraries. It has no side effects, creates no data, executes no code, and makes no destructive or financial changes. It falls squarely into the Read category with low severity since misuse would only expose informational content about available libraries.

From the tool's own definition: "The tool 'list_libraries' retrieves and lists available libraries with their metadata (slug, name, source, description). The verb 'List' and the phrase 'get a' indicate a read-only query operation with no modification of state."

## Use case

AI agents call list_libraries to retrieve information from Cloudflare 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 Cloudflare:

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