Zed LiveVariant register_test

How to: Zed LiveVariant register_test

client:Zed transport:streamable-http tool:register_test

Add LiveVariant to Zed

  1. 01

    Open ~/.config/zed/settings.json and merge this in. Keep any servers already there.

{
  "context_servers": {
    "livevariant": {
      "url": "https://livevariant.com/mcp"
    }
  }
}
  1. 02

    Save the file and restart Zed.

  2. 03

    Ask for something register_test does. Zed 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.

Merge this into your existing settings object — do not replace the file. Zed 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.
