VS Code

Add a .vscode/mcp.json file to your project. VS Code asks for the API key the first time and stores it securely:

{
  "inputs": [
    {
      "type": "promptString",
      "id": "vaif-api-key",
      "description": "VAIF Studio API key",
      "password": true
    }
  ],
  "servers": {
    "vaif-studio": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@vaifstudio/mcp"
      ],
      "env": {
        "VAIF_PROJECT_ID": "your-project-id",
        "VAIF_API_KEY": "${input:vaif-api-key}"
      }
    }
  }
}

Or add it for your user from a terminal:

code --add-mcp '{"name":"vaif-studio","command":"npx","args":["-y","@vaifstudio/mcp"],"env":{"VAIF_PROJECT_ID":"your-project-id"}}'

The tools appear in the Chat view when it is in agent mode.

Settings

Variable	Needed for	Where it comes from
VAIF_PROJECT_ID	Everything	Your project ID, from the console or vaif.config.json
VAIF_API_KEY	The row tools (query_rows, insert_row and the rest) and signed file links	A project API key, from the project’s Overview or Project settings > API keys. get_signed_url needs a key with the storage scope
VAIF_AUTH_TOKEN	Schema, SQL, storage, functions and key tools	Optional. Without it, the server uses the sign-in that vaif login saved in ~/.vaif/auth.json, read again on every call
VAIF_API_URL	A local or self-hosted API only	Defaults to https://api.vaif.studio

Keep API keys out of files you commit.

See MCP server for the tools and what each one can change.
