Claude Code Switch (ccm)

Switch Claude Code between AI providers with one command.

Quick Start

First-Time Setup

1. Configure API Keys

ccm config

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

# Required for each provider you want to use
DEEPSEEK_API_KEY=sk-...
KIMI_API_KEY=...
GLM_API_KEY=...
QWEN_API_KEY=...
MINIMAX_API_KEY=...
ARK_API_KEY=...           # For Doubao/Seed
OPENROUTER_API_KEY=...    # For OpenRouter
CLAUDE_API_KEY=...        # Optional, for Claude API (vs subscription)

2. Verify Setup

ccm status    # Check current configuration

Basic Usage

Switch Provider (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 seed              # Doubao/Seed
ccm claude            # Claude official

Switch + Launch Claude Code

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

Check Status

ccm status             # Show current model and API key status
ccm current-account    # Show current Claude Pro account

Update Config

When model IDs change in new versions, update your config:

ccm update-config      # Update outdated model IDs to latest defaults

Get Help

ccm help               # Show all commands
ccc                    # Show ccc usage (no args)

Advanced Features

Claude Pro Account Management

Switch between multiple Claude Pro subscriptions:

# Save current logged-in account
ccm save-account work

# Switch to saved account
ccm switch-account work

# List all saved accounts
ccm list-accounts

# Show current account
ccm current-account

# Delete saved account
ccm delete-account work

User-Level Settings (Highest Priority)

Write settings directly to ~/.claude/settings.json. This overrides everything including environment variables and is useful when you have other tools (like Quotio) that also modify this file.

# Set provider at user level
ccm user glm global      # GLM global for all projects
ccm user glm china       # GLM China for all projects
ccm user deepseek        # DeepSeek for all projects
ccm user claude          # Claude official for all projects

# Reset to environment variable control
ccm user reset           # Remove ccm settings, use env vars instead

When to use:

You have Quotio or another proxy that sets ~/.claude/settings.json
You want a persistent default that survives shell restarts
Environment variables are being overridden by something else

Project-Only Override

Override settings for a specific project (keeps global settings intact):

# In your project directory
ccm project glm global    # Use GLM for this project only
ccm project glm china     # Use GLM China for this project
ccm project reset         # Remove project override

This creates/removes .claude/settings.local.json in the current project.

Launch with Account

ccc work                  # Switch to 'work' account, then launch
ccc claude:personal       # Switch to 'personal' account + use Claude

Configuration

Priority Order (highest to lowest)

~/.claude/settings.json (env section) - User-level settings
.claude/settings.local.json - Project-level settings
~/.ccm_config file - Always reloads on each ccm command
Environment variables (only used if config value is a placeholder)

Config File Location

~/.ccm_config

Without RC Injection

If you installed with --no-rc or want to use from cloned repo:

# Switch model (apply env vars to current shell)
eval "$(ccm glm global)"
eval "$(./ccm.sh glm china)"

# Or use the wrapper scripts directly
./ccm glm global         # Just prints exports
./ccc glm china          # Switch + launch

Notes

7 env vars exported per provider: ANTHROPIC_BASE_URL, ANTHROPIC_AUTH_TOKEN, ANTHROPIC_MODEL, ANTHROPIC_DEFAULT_OPUS_MODEL, ANTHROPIC_DEFAULT_SONNET_MODEL, ANTHROPIC_DEFAULT_HAIKU_MODEL, CLAUDE_CODE_SUBAGENT_MODEL
Claude official: Uses your Claude Code subscription by default, or CLAUDE_API_KEY if set
OpenRouter: Requires explicit ccm open <provider> command
Project override: Only affects the current project via .claude/settings.local.json
