## Why neuron_get_group_participants is rated Low

This tool queries and returns group participant information without creating, modifying, deleting, or executing any operations. It is a straightforward read operation with minimal risk—exposing participant lists in groups accessible through an authorized channel carries low blast radius since it retrieves existing metadata rather than altering state or triggering external actions.

From the tool's own definition: "Tool name and description both indicate a retrieval operation: 'Retrieve the list of participants in a specific WhatsApp group'."

## Use case

AI agents call neuron_get_group_participants to retrieve information from Neuron 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 Neuron:

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