Claude Settings Editor (macOS)

A simple standalone web UI helper tool to read and edit the environment variables (env) object in your Claude Code CLI configuration file (~/.claude/settings.json) on macOS.

Installation

Install globally using npm:

npm install -g @somfan2001/claudeenv

Quick Start

Run the following command in your terminal to start the local helper server:

claudeenv

1. Open http://localhost:20129 in your web browser.
2. Edit your environment variables (e.g. ANTHROPIC_AUTH_TOKEN, ANTHROPIC_BASE_URL, or add custom envs).
3. Click "Lưu Cấu Hình" (Save Configuration) to save directly back to your local settings.json file.
4. When finished, simply click the red "Tắt Server" (Shutdown Server) button on the web page to stop the server process and close the browser tab.

Why use this?

Since macOS configurations can be tricky and Claude Code settings are stored outside of workspace boundaries, this tool helps you bypass IDE write restrictions (like Trae or VS Code sandbox EPERM errors) by running locally with native terminal permissions.
