## Why domain.namesilo.check is rated Low

Queries domain availability and pricing without modifying data or triggering registrations.

From the tool's own definition: "Check if domain names are available for registration. Returns availability status, registration price, and renewal price."

## Use case

AI agents call domain.namesilo.check to retrieve information from Apibase 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 Apibase:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "domain.namesilo.check": {}
  }
}
```
