# bazel_ios_device_log_start

Start capturing logs from a connected physical iOS device. Tries pymobiledevice3 first (iOS 17+ via CoreDevice tunnel), falls back to idevicesyslog for older devices.

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

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

## Why bazel_ios_device_log_start is rated High

This tool executes a command to begin a continuous logging/monitoring process on a connected device. While not destructive and not creating lasting data modifications, it triggers an external operation whose behavior depends on the target device state and arguments provided. The tool interacts with device system services, making it an Execute category tool.

From the tool's own definition: "Starts log capturing from a physical iOS device using pymobiledevice3 or idevicesyslog - actively initiates a system operation with external effects"

## Use case

AI agents invoke bazel_ios_device_log_start to trigger actions in XcodeBazelMCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches XcodeBazelMCP:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "bazel_ios_device_log_start": {
      "limits": [
        {
          "counter": "bazel_ios_device_log_start_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
