Drive a real phone from Hermes with one phone_exec tool: an iPhone via iPhone Mirroring on a Mac, an Android over adb, or a cloud phone from Phone Harness Cloud.

## Good to know before installing

Runs model-written Python on this computer with your user's permissions through the phone-harness package (installed from PyPI); every phone_exec call goes to Hermes's approval prompt unless you opt in to classifier auto-run, a heuristic, bypassable check that decides which scripts ask first; taps and types into your real phone and its apps and accounts; screenshots go to the system temp folder and are attached to the tool result for vision models; a cloud phone streams its screen to Phone Harness Cloud, bills by the minute, and uses phone-harness's own cloud sign-in (~/.config/phone-harness/auth.json); phone-harness's PostHog telemetry (script text, script output, helper arguments) is off under Hermes unless you opt in.

From the plugin's catalog listing.

## How to install

1. Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.

```bash
hermes plugins install phone-harness
```

2. Said no? Turn it on later:

```bash
hermes plugins enable phone-harness
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
