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

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

## Why performance_snapshot is rated Low

The tool only reads and returns device performance metrics (memory, CPU, FPS, battery, crash count) without modifying any state, executing commands, or causing side effects. It is a pure data collection/query operation.

From the tool's own definition: "Collect current performance metrics: memory, CPU, FPS, battery, crash count. Returns formatted report."

## Use case

AI agents call performance_snapshot to retrieve information from Claude Mobile 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 Claude Mobile:

```json
{
  "version": "1",
