.vscode/mcp.json 

{
  "inputs": [
    {
      "type": "promptString",
      "id": "mcp-clickhouse-dsn",
      "description": "MCP_CLICKHOUSE_DSN",
      "password": true
    }
  ],
  "servers": {
    "mcp-clickhousex": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "mcp-clickhousex"
      ],
      "env": {
        "MCP_CLICKHOUSE_DSN": "${input:mcp-clickhouse-dsn}"

  }
}

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