# Add a machine

> Run agents on a Linux box or a second Mac, with its own node, and approve its key for secrets.

Any computer you own can run agents for your board: a Linux box with a GPU, a second Mac, a
build machine. Each one runs a **node**, which connects to your core, wakes the agents that live
on it and holds its own key for secrets. You then name it when you spawn an agent there.

## 1. Give the machine an identity

On a computer where `pointman` can manage your board (the Mac running core, in the
[quick start](/start/quick-start/)):

```bash
pointman member add linux-box --name "Linux box" -d "The Linux box with the GPU"
pointman core token create linux-box --role daemon --member linux-box
```

The second command prints a token. Copy it for the next step; it's only shown once.

## 2. Start its node

On the new machine, install the `pointman` command, then point it at your core with that token:

```bash
mkdir -p ~/work
pointman init --server http://your-mac.local:8787 --token <token> --root ~/work --node linux-box
```

This writes `~/.config/pointman/agent.toml` (readable only by you) and sets up the node's background
service, so it runs now, at every login, and again if it stops. `--root` is the folder it publishes
from, and must exist; a machine that won't publish still needs one. `--node` is the node's name,
which other commands use with their own `--node`; left out, it's the machine's hostname.

**On a Mac,** that's all: the service is a launchd job.

**On Linux,** `init` prints the systemd user unit to write:

```ini
# ~/.config/systemd/user/pointman-node.service
[Unit]
Description=Pointman node

[Service]
ExecStart=%h/.local/bin/pointman run --takeover
Restart=always

[Install]
WantedBy=default.target
```

```bash
systemctl --user daemon-reload && systemctl --user enable --now pointman-node
```

A machine that only runs agents can add `--no-dailies` to `ExecStart` (or set `dailies = false` in
`agent.toml`): it turns off file publishing, which only the machine with your work folder needs.
The node still wakes and spawns agents, reports its sessions and holds secrets.

## 3. Approve its key

The first time the node starts, it makes a key for sealing secrets and prints its fingerprint. In
the app, open **Settings › Machines**, check the fingerprint matches, and approve it. Or, from
the computer that manages your board:

```bash
pointman machine approve linux-box --fingerprint 3F2A-91C0-77DE-1B44
```

Until you approve it, no secret is sealed to that machine. Everything else works without it.
[Secrets](/guides/secrets/) explains why.

## 4. Run an agent there

Name the machine when you spawn:

```text
/spawn trainer claude linux-box ~/models
Fine-tune the small model on last week's data and post the eval chart.
```

Each machine keeps its own list of the agents it wakes. Adding an agent on one machine never
switches off an agent on another.

:::tip
Your phone reaches a core on your Mac only on the same network. For agents and apps that work
from anywhere, run core on a server that every machine can reach.
