## Why greet is rated Low

This is a straightforward interaction tool that outputs a greeting. It performs no data retrieval beyond generating a simple response, makes no modifications, executes no code or commands, and causes no irreversible changes. The closest fit is Read (as it involves retrieving/displaying information) despite being more accurately classified as a stateless interaction. It poses minimal risk.

From the tool's own definition: "Tool named 'greet' with description 'Greet the user' — a simple greeting function that retrieves or displays a message to the user with no side effects, data modification, or external operations."

## Use case

AI agents call greet to retrieve information from Lucy Apro 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 Lucy Apro:

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