VS Code

In VS Code, the simplest option is the official Claude Code extension: the same agent as in the terminal, with a panel, inline diffs and file mentions. It’s configured like the terminal version, with two extra VS Code settings.

Setup

1. Install the extension

   Open the Extensions view (Ctrl+Shift+X, or Cmd+Shift+X on Mac), search for Claude Code (publisher: Anthropic) and click Install. VS Code 1.94 or later is required.

2. Turn off the login prompt

   Open settings (Ctrl+, or Cmd+,), search for “Claude Code login” and tick Disable Login Prompt. Otherwise the extension asks for a claude.ai account on first launch.

3. Point the extension at Kloria

   Open the command palette (Ctrl+Shift+P or Cmd+Shift+P), run Preferences: Open User Settings (JSON) and add:

   settings.json (user)

   {
     "claudeCode.disableLoginPrompt": true,
     "claudeCode.environmentVariables": [
       { "name": "ANTHROPIC_BASE_URL", "value": "https://api.kloria.dev" },
       { "name": "ANTHROPIC_AUTH_TOKEN", "value": "sk-…" },
       { "name": "ANTHROPIC_DEFAULT_OPUS_MODEL", "value": "claude-opus-5-5" },
       { "name": "ANTHROPIC_DEFAULT_SONNET_MODEL", "value": "claude-sonnet-5" },
       { "name": "ANTHROPIC_DEFAULT_HAIKU_MODEL", "value": "claude-sonnet-5" }
     ]
   }

   If the file already has settings, add these two keys inside the existing braces.

4. Reload and test

   Run Developer: Reload Window from the palette, open the Claude Code panel (spark icon at the top right of the editor) and send a message.

Already set up for the terminal?

If you followed the Claude Code page, the extension already reads ~/.claude/settings.json. Still keep the key in claudeCode.environmentVariables: the extension checks for a key before starting Claude Code, and only looks at that setting for it.

Good to know

• VS Code user settings aren’t versioned with your projects, so the key doesn’t end up in a repository. Don’t put it in a project’s .vscode/settings.json.
• Model selection, /model and /status work as in the terminal.
• Features tied to a claude.ai account (plan usage bars, voice dictation, cloud sessions) aren’t available through a gateway.
• The extension also installs in Cursor and other VS Code-based editors, with the same configuration.

For errors, the Claude Code and Troubleshooting pages apply as is.
