Connect Crush

Install Crush and set up a model provider.

1. Add the connection
Add this to crush.json or .crush.json in your project, or to ~/.config/crush/crush.json. If the file already lists MCP servers, add only the guardch entry.
crush.json
Add the entry below. Keep any other servers already in the file.
```
{
  "mcp": {
    "guardch": {
      "type": "http",
      "url": "https://api.guard.ch/mcp",
      "oauth": true
    }
  }
}
```
2. Sign in and allow access
Start Crush and begin the sign-in for guardch from its MCP list. Sign in and allow access on the Guard.ch page that opens.
3. Try it in a new chat
Check in Crush's MCP list that guardch is connected, then send the task below.

Open example.com in a Guard.ch browser and tell me what the page says.

Need help?

If guardch does not connect, check that oauth is set to true and the URL is exactly as shown. Run crush logs to see the error.

Hand over a running session

Choose “Hand off to an agent” in the Guard.ch viewer and paste the prepared prompt into your assistant’s chat. The session ID in that prompt lets the assistant continue in the same browser. Sign your assistant in with the same Guard.ch account.
