claude-cfg

CLI tool to easily manage and switch Claude Code configurations across multiple LLM providers.

Overview

claude-cfg helps you quickly configure Claude Code to work with different LLM providers including:

• Anthropic (default)
• OpenRouter - Access various models through a unified API
• z.ai - GLM Coding Plan with 3× usage at lower cost

Instead of manually editing configuration files or environment variables, claude-cfg provides an interactive CLI to manage your Claude Code setup.

Installation

npm install -g claude-cfg

Usage

Simply run:

claude-cfg

The interactive CLI will guide you through:

1. Selecting your preferred LLM provider
2. Entering required credentials (API keys)
3. Configuring provider-specific settings
4. Automatically updating your Claude Code configuration

Supported Providers

• Supports model overrides and presets
• Requires OpenRouter API key from openrouter.ai

z.ai

Configuration

claude-cfg automatically manages your Claude Code configuration by updating:

• Environment variables (alternative method)

All changes are made safely with backups of existing configurations.

Requirements
