## Why verify_charity is rated Low

This tool queries official government charity registries using identifiers (EIN, Charity Commission number, etc.) and retrieves matching records. It performs a lookup with no side effects, mutations, or irreversible actions. The return value is a matched charity record or null, confirming it is purely informational retrieval.

From the tool's own definition: "Tool description states 'Look up a charity' and 'Returns the matched charity or null' — core read operation. No modification, deletion, or execution described."

## Use case

AI agents call verify_charity to retrieve information from Charity Registry 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 Charity Registry:

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