Install polydev in VS Code

.vscode/mcp.json 

{
  "inputs": [
    {
      "type": "promptString",
      "id": "polydev-user-token",
      "description": "POLYDEV_USER_TOKEN",
      "password": true
    }
  ],
  "servers": {
    "polydev": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "polydev-ai"
      ],
      "env": {
        "POLYDEV_USER_TOKEN": "${input:polydev-user-token}"
      }
    }
  }
}

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