  "jsonrpc": "2.0",

  "params": {
    "name": "list_groups",

## Why list_groups is rated Low

This tool performs a read-only operation to retrieve and display contact groups from the user's address book. It has no capacity to modify, delete, or execute actions—only to list existing data. The blast radius is minimal since querying contact groups poses no risk of data loss, financial impact, or unauthorized execution.

From the tool's own definition: "Tool name 'list_groups' and description 'List all contact groups' indicate a query operation that retrieves contact group information without modification or side effects."

## Use case

AI agents call list_groups to retrieve information from AirMCP 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 AirMCP:

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