cd claude-code-switch
uv tool install .

# 2. Configure API keys
ccm config

# 3. Switch and use
ccm glm global        # switch to GLM (sets env vars)
ccc glm global        # switch + launch Claude Code

---

Installation

git clone https://github.com/gameofdimension/claude-code-switch.git
cd claude-code-switch
uv tool install .

Shell Integration (Optional)

For automatic env var handling, run the installer:

./install.sh              # User-level (default)
./install.sh --system     # System-level
./install.sh --project    # Project-only
./install.sh --no-rc      # Skip shell rc injection

After pulling latest changes:

uv tool install . --reinstall
# or
./install.sh

First-Time Setup

1. Configure API Keys

ccm config

This opens ~/.ccm_config. Add your API keys:

DEEPSEEK_API_KEY=sk-...
KIMI_API_KEY=...
GLM_API_KEY=...
QWEN_API_KEY=...
MINIMAX_API_KEY=...
ARK_API_KEY=...           # For Doubao/Seed
STEPFUN_API_KEY=...       # For StepFun
OPENROUTER_API_KEY=...    # For OpenRouter
CLAUDE_API_KEY=...        # Optional, for Claude API

2. Verify Setup

ccm status

Basic Usage

Switch Provider (sets env vars in current shell)

ccm glm global        # GLM global (default)
ccm glm china         # GLM China
ccm deepseek          # DeepSeek
ccm kimi global       # Kimi global
ccm kimi china        # Kimi China
ccm qwen global       # Qwen global
ccm minimax           # MiniMax
ccm stepfun           # StepFun
ccm seed              # Doubao/Seed
ccm claude            # Claude official

Switch + Launch Claude Code

ccc glm global        # Switch to GLM, then launch
ccc open glm          # Via OpenRouter

Other Commands

ccm status            # Show current configuration
ccm help              # Show all commands

Advanced Features

User-Level Settings (Highest Priority)

Write to ~/.claude/settings.json. Overrides everything.

ccm user glm global      # GLM for all projects
ccm user reset           # Restore env var control

When to use:

• Other tools modify ~/.claude/settings.json
• You want persistent defaults across shell restarts

Project-Only Override

Override settings for a specific project:

ccm project glm global   # GLM for this project only
ccm project reset        # Remove project override

Creates .claude/settings.local.json in the project.

---

Configuration

Priority Order (highest to lowest)

1. ~/.claude/settings.json - User-level settings
2. .claude/settings.local.json - Project-level settings
3. ~/.ccm_config - Config file (reloads on each command)
4. Environment variables
