## Why get_stranger_info is rated Low

This tool retrieves data about a stranger without modifying, deleting, or executing operations. It falls squarely into the Read category. Severity is low because the blast radius of retrieving user information is limited in scope and does not enable account compromise, financial damage, or destructive actions by itself.

From the tool's own definition: "Tool name 'get_stranger_info' and description 'Get stranger information' indicate a retrieval operation with no side effects. The verb 'Get' combined with 'information' clearly signals a read-only query."

## Use case

AI agents call get_stranger_info to retrieve information from NapCat MCP Server 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 NapCat MCP Server:

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