## Why catalog_search is rated Low

This tool retrieves or queries data from a catalog without modifying, deleting, or executing operations. It has no capability to modify state, trigger external actions, or commit financial transactions. The low severity reflects minimal blast radius—a misused search query returns information only.

From the tool's own definition: "Tool description states 'Search the live 1cent catalog without payment or external URL fetch.' The verb 'search' and explicit statement that it performs queries 'without payment' or external fetches indicate a read-only operation with no side effects."

## Use case

AI agents call catalog_search to retrieve information from 1cent 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 1cent:

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