Spawner

Open source, self-hosted preview environment manager: a copy of your app for each git branch, on your own server, with its own URLs, database and logs, for teams and their coding agents.

    "spawner": {
      "command": "npx",
      "args": [
        "spawner-cli"
      ]
    }
  }
}

Please read this MCP repository and install it into my current environment:

Known working client config (can write into mcp.json):
{
  "mcpServers": {
    "spawner": {
      "command": "npx",
      "args": [
        "spawner-cli"
      ]
    }
  }
}

Please: 1) check README for deps and env vars; 2) write config for my client; 3) if secrets are missing, tell me what to fill — do not invent values.
