## Why search_works is rated Low

This tool searches for works on a Japanese novel publishing platform. Search operations are inherently read-only—they query and retrieve information without creating, modifying, deleting, or executing code. The blast radius of misuse is minimal; an agent could only retrieve unwanted search results, not cause side effects.

From the tool's own definition: "Tool name 'search_works' and description 'カクヨムで作品を検索' (search works on Kakuyomu) indicates a search operation that retrieves data without modification."

## Use case

AI agents call search_works to retrieve information from Kakuyomu MCP Server 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 Kakuyomu MCP Server:

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