## Why domains_checkDomainAvailabilityV1 is rated Low

This tool performs a read-only query against the Hostinger API to check domain name availability. It has no side effects, does not create, modify, delete, or execute any operations. The rate limit (10 requests per minute) and the emphasis on checking before purchase further confirm it is a passive information retrieval tool.

From the tool's own definition: "Tool description states 'Check availability of domain names' and 'verify domain availability before purchase' — these are query operations that retrieve availability status without modifying, executing, or deleting any data."

## Use case

AI agents call domains_checkDomainAvailabilityV1 to retrieve information from Hostinger Api 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 Hostinger Api:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "domains_checkDomainAvailabilityV1": {}
  }
}
```
