## Why gutenberg_book is rated Low

This tool retrieves read-only information about books from Project Gutenberg (a public digital library). It has no capability to modify, delete, or execute operations—it simply fetches and returns book metadata. The blast radius of misuse is minimal as the data is public and retrieving details causes no harm.

From the tool's own definition: "Tool name 'gutenberg_book' and description 'Get details for a specific Project Gutenberg book by ID' indicate a retrieval operation. The verb 'Get' and the context of querying a public book database confirm no data modification or side effects."

## Use case

AI agents call gutenberg_book to retrieve information from UnClick 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 UnClick:

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