Install server in VS Code

.vscode/mcp.json 

{
  "inputs": [
    {
      "type": "promptString",
      "id": "callmcp-config",
      "description": "CALLMCP_CONFIG",
      "password": true
    },
    {
      "type": "promptString",
      "id": "callmcp-default-driver",
      "description": "CALLMCP_DEFAULT_DRIVER",
      "password": true
    }
  ],
  "servers": {
    "server": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@callmcp/server"
      ],
      "env": {
        "CALLMCP_CONFIG": "${input:callmcp-config}",
        "CALLMCP_DEFAULT_DRIVER": "${input:callmcp-default-driver}"
      }
    }
  }
}

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