## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "list_running_apps",
    "arguments": {}
  }
}
```

## Why list_running_apps is rated Low

This tool queries the system state to retrieve information about currently running processes. It performs a read-only operation with no ability to modify, execute, or delete anything. The blast radius is minimal—disclosure of running apps could inform an attacker about system state but cannot directly cause harm.

From the tool's own definition: "Tool name 'list_running_apps' and description 'List all running applications with name, bundle identifier, PID, and visibility' indicates data retrieval only."

## Use case

AI agents call list_running_apps 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_running_apps": {}
  }
}
```
