## Why url_extract is rated Low

Despite empty description, the naming pattern and context (pay-per-call URL intelligence) indicate this tool retrieves or extracts URL data without side effects. It fits the Read category (search, get, fetch). The 1cent server charges for calls but does not modify state.

From the tool's own definition: "Tool name 'url_extract' suggests data retrieval/parsing of URL information. No description provided, limiting confidence."

## Use case

AI agents call url_extract 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": {
    "url_extract": {}
  }
}
```
