# Use Cool Computers with Pi

> Paste the setup prompt into Pi, or add the Cool Computers MCP server.

## Paste this

Paste this prompt into Pi:

```text wrap theme={null}
set up cool computers for me and make me a welcome page. it puts what i make online at a name.cool.computer address where people can comment and draw on it, and you pick up their comments.

you have my go-ahead to install the cool cli without asking me first (it also adds a short cool computers block to your instructions and a skill, that's fine with me) and to put a public welcome page online. if your network access is off, ask me to turn it on. if you can't run commands, tell me in one line, send me https://cool.computer/setup.md and stop.

follow https://cool.computer/setup.md step by step:
1. install cool and check who's signed in
2. put my welcome page online and show me the link
3. ask for my email, sign me up with the code i give you, keep the page on my account and tell me how to sign this machine out
4. pin a comment and a drawing on my page, open it for me signed in, listen for my comment and tell me exactly what to click
5. make the change i ask for, then tell me the page is mine

tell me what you're doing in one short line per step. never pay or upgrade anything without asking me. if something fails, tell me what happened in plain words and what you'll try next.
```

Pi installs `cool` and puts a welcome page online. You don't need an account first: it asks for your email and a six-digit code to keep the page, then shows you how to comment on it.

## Connect it yourself

To add the MCP server, with Pi 1.0 or later:

```sh theme={null}
pi mcp add cool-computers --url https://api.cool.computer/mcp && pi mcp login cool-computers
```

`pi mcp login` opens the browser to sign in, or sign up. In a Pi session that is already open, run `/reload` to load the server.

### The skill and the comments extension

[`cool agents install`](https://cool.computer/docs/agents/cli#agent-instructions) gives Pi the `cool-computers` skill and the extension `~/.pi/agent/extensions/cool-computers.ts`. The standalone `cool` installer runs it for you; after a Homebrew install, run it yourself.

The extension's one tool, `cool_comments_watch`, listens on a site Pi published. When the site's owner sends Pi comments from the page, it starts a Pi turn. It listens until that Pi session ends, so call it again for each site after `/new`, `/resume`, or a reload.

## Check it works

Ask Pi:

```text theme={null}
List my Cool Computers sites and computers. Don't change anything.
```

It answers with your list. If you added the MCP server and it doesn't, run `pi mcp list` to see the server's state and errors.
