.vscode/mcp.json 

{
  "inputs": [
    {
      "type": "promptString",
      "id": "crossref-mailto",
      "description": "CROSSREF_MAILTO",
      "password": true
    },
    {
      "type": "promptString",
      "id": "crossref-plus-token",
      "description": "CROSSREF_PLUS_TOKEN",
      "password": true
    }
  ],
  "servers": {
    "crossref-mcp": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "crossref-mcp"
      ],
      "env": {
        "CROSSREF_MAILTO": "${input:crossref-mailto}",
        "CROSSREF_PLUS_TOKEN": "${input:crossref-plus-token}"
      }
    }
  }
}

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