Zed

There is a Zed editor extension available in the official extension gallery. During installation it will ask for an API token which will be added to your settings, or you can manually configure:

// ~/.config/zed/settings.json
{
  "context_servers": {
    "mcp-server-buildkite": {
      "settings": {
        "buildkite_api_token": "your-buildkite-token-here"
      }
    }
  }
}
