## Why check_ico_insolvency is rated Low

This is a pure data retrieval operation against a Czech insolvency registry (ISIR). It queries immutable public records and returns informative results without side effects. The tool has negligible blast radius—worst case an AI agent could learn false information about a company's insolvency status, but cannot modify records, execute code, or cause financial harm. Classified as Read with low severity.

From the tool's own definition: "Tool description states it 'Check[s] whether a Czech company...has any active insolvency proceeding' and 'Returns' specific data fields or 'no record'."

## Use case

AI agents call check_ico_insolvency to retrieve information from Isir 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 Isir:

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