Windsurf

Open Windsurf Settings > Cascade > MCP servers > View raw config (the file ~/.codeium/windsurf/mcp_config.json) and add:

{
  "mcpServers": {
    "vaif-studio": {
      "command": "npx",
      "args": [
        "-y",
        "@vaifstudio/mcp"
      ],
      "env": {
        "VAIF_PROJECT_ID": "your-project-id",
        "VAIF_API_KEY": "your-api-key"
      }
    }
  }
}

Refresh the server list; the VAIF Studio tools appear in Cascade.

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.
