Why ccc?

ccc is a CLI tool that provides seamless provider switching for Claude Code. Switch between Kimi, GLM, MiniMax, and other providers with one command.

Quick Start

1. Install

Option A: One-line install (Linux / macOS)

OS=$(uname -s | tr '[:upper:]' '[:lower:]'); ARCH=$(uname -m | sed -e 's/x86_64/amd64/' -e 's/aarch64/arm64/'); curl -LO "https://github.com/guyskk/claude-code-config-switcher/releases/latest/download/ccc-${OS}-${ARCH}" && sudo install -m 755 "ccc-${OS}-${ARCH}" /usr/local/bin/ccc && rm "ccc-${OS}-${ARCH}" && ccc --version

Option B: Download from Releases

Download the binary for your platform (ccc-darwin-arm64, ccc-linux-amd64, etc.) and install to /usr/local/bin/.

2. Configure

If you already have ~/.claude/settings.json, the first time you run ccc it will prompt to migrate and automatically generate the ccc config at ~/.claude/ccc.json.

You can also create the config file manually:

{
  "settings": {
    "permissions": {
      "defaultMode": "bypassPermissions"
    }
  },
  "providers": {
    "glm": {
      "env": {
        "ANTHROPIC_BASE_URL": "https://open.bigmodel.cn/api/anthropic",
        "ANTHROPIC_AUTH_TOKEN": "YOUR_API_KEY_HERE",
        "ANTHROPIC_MODEL": "glm-4.7"
      }
    },
    "kimi": {
      "env": {
        "ANTHROPIC_BASE_URL": "https://api.moonshot.cn/anthropic",
        "ANTHROPIC_AUTH_TOKEN": "YOUR_API_KEY_HERE",
        "ANTHROPIC_MODEL": "kimi-k2-thinking"
      }
    }
  }
}

Security Warning: bypassPermissions allows Claude Code to execute tools without confirmation. Only use this in trusted environments.

3. Use

# Show help
ccc --help

# Switch to a provider and run Claude Code
ccc glm

# Run with current provider
ccc

# Pass any Claude Code arguments
ccc glm -p

4. Validate (Optional)

Verify your provider configuration:

# Validate current provider
ccc validate

# Validate all providers
ccc validate --all

Patch Command: Replace claude with ccc

Make ccc your default Claude Code by replacing the system claude command.

# Replace claude command with ccc (requires sudo)
sudo ccc patch

# After patching, `claude` command now uses ccc
claude --help    # Shows ccc help

# Restore original claude command
sudo ccc patch --reset

Configuration

Config file location, default: ~/.claude/ccc.json

Configuration Merge Strategy

When you run ccc, your existing settings.json is read and deep-merged with ccc.json. Priority: user settings.json > provider > base settings. Your manual edits, plugins, and hooks are preserved; provider env is passed via command line and never written into settings.json.

Environment Variable Handling

Claude Code's settings.json env field overrides environment variables passed by ccc when launching claude. To ensure provider env takes precedence, ccc passes provider env via the --settings CLI parameter, which has higher priority than settings.json.
