{
  "inputs": [
    {
      "type": "promptString",
      "id": "mem0-api-key",
      "description": "MEM0_API_KEY",
      "password": true
    },
    {
      "type": "promptString",
      "id": "redis-url",
      "description": "REDIS_URL",
      "password": true

  ],
  "servers": {
    "r3": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@n3wth/r3"
      ],
      "env": {
        "MEM0_API_KEY": "${input:mem0-api-key}",
        "REDIS_URL": "${input:redis-url}"
      }
    }
  }
}

VS Code prompts for each input the first time the server starts, so no secret is written to the file. VS Code docs
