      "args": [

        "HOMEASSISTANT_TOKEN": "${input:homeassistant-token}"
      }
    }

Any client

Most clients that start local servers accept this shape:

{
  "mcpServers": {
    "home-assistant": {
      "command": "uvx",
      "args": [
        "ha-mcp@latest"
      ],
      "env": {
        "HOMEASSISTANT_URL": "<YOUR_HOMEASSISTANT_URL>",
        "HOMEASSISTANT_TOKEN": "<YOUR_HOMEASSISTANT_TOKEN>"
      }
    }
  }
}

Zed puts servers under context_servers in its settings, with the same command, args and env fields.
