Install letin: Power Query (M) in VS Code

.vscode/mcp.json

{
  "inputs": [
    {
      "type": "promptString",
      "id": "letin-home",
      "description": "LETIN_HOME",
      "password": true
    }
  ],
  "servers": {
    "letin": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "letin"
      ],
      "env": {
        "LETIN_HOME": "${input:letin-home}"
      }
    }
  }
}

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