# Cool Computers in Claude Code

> Install the Cool Computers plugin in Claude Code for the MCP server and the cool-computers skill, or add the MCP server on its own.

## Install the plugin

The [Cool Computers plugin](https://github.com/The-Money-Company-Limited/cool-computers) adds the remote MCP server `https://api.cool.computer/mcp` and the `cool-computers` skill, which teaches Claude when to publish a page, how to answer comments and drawings, and when a site needs a VM. Run in Claude Code:

```text
/plugin marketplace add The-Money-Company-Limited/cool-computers
/plugin install cool-computers@cool-computers
```

Then run `/mcp`, choose `cool-computers` and sign in to Cool Computers in the browser that opens.

## MCP server only

To add the server without the skill, for every project:

```sh
claude mcp add --scope user --transport http cool https://api.cool.computer/mcp
```

Run `/mcp` in Claude Code, choose `cool` and sign in.

To use an API key instead of signing in, keep the key in `COOL_API_KEY` and send it as a bearer token:

```sh
claude mcp add --scope user --transport http cool https://api.cool.computer/mcp --header "Authorization: Bearer $COOL_API_KEY"
```

Create a key in Settings at [www.cool.computer/account](https://www.cool.computer/account), or over HTTP as the [credential reference](/authentication.md) shows. The key is shown once.

## Check it works

Ask Claude:

```text
List my Cool Computers sites and computers. Don't change anything.
```

It calls `cool_list_computers` and answers with your list.

## Without an account

Sign-up is invite-only for now. Without an account, Claude can still publish with the [cool CLI](/install) and give you a link to claim the site; [/agents.md](/agents.md) is the step-by-step runbook it follows.
