Windsurf LiveVariant register_test

How to: Windsurf LiveVariant register_test

client:Windsurf transport:streamable-http tool:register_test

Add LiveVariant to Windsurf

  1. 01

    Open ~/.codeium/windsurf/mcp_config.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "livevariant": {
      "serverUrl": "https://livevariant.com/mcp"
    }
  }
}
  1. 02

    Save the file and restart Windsurf.

  2. 03

    Ask for something register_test does. Windsurf lists the server's tools on connect and calls register_test itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that LiveVariant's identifier in your config matches the one above exactly.

Global only — Windsurf has no per-project MCP config. Refresh Cascade after saving. Windsurf docs

Set these first

LiveVariant will not start until these are set, so register_test never becomes available.

  • LIVEVARIANT_SERVER_URL
  • LIVEVARIANT_API_TOKEN
  • LIVEVARIANT_ASSET_UPLOAD_TOKEN

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 24 September 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
