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

```json
{
  "jsonrpc": "2.0",

  "method": "tools/call",
  "params": {
    "name": "adb_current_activity",
    "arguments": {}

## Why adb_current_activity is rated Low

This tool retrieves information about the current state of the Android device (currently focused activity and window stack) without modifying, executing, or destroying anything. It is a straightforward query that returns data about the UI state. The blast radius of misuse is minimal—an agent could only learn what is currently displayed, which is low-risk information disclosure.

From the tool's own definition: "Tool name and description indicate it 'Get the currently focused activity and window stack'—a query operation with no side effects. The verb 'get' and the passive nature of reading activity state confirms this is a read-only operation."

## Use case

AI agents call adb_current_activity to retrieve information from Deepadb 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 Deepadb:

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