cce - Claude Code Environment Manager

Manage multiple Claude Code configurations and switch between different providers/models in different terminals.

What it does

Claude Code reads ~/.claude/settings.json for env overrides (API key, base URL, model), which take precedence over process environment variables. This makes it impossible to run different providers in different terminals.

cce solves this by using --settings to inject per-environment overrides, so you can run DeepSeek in terminal 1 and GLM in terminal 2 simultaneously — no global config changes.

Install

npm install -g @sukeyu/cce

Quick Start

# Add an environment
cce add deepseek \
  --provider deepseek \
  --model deepseek-v4-flash \
  --api-key sk-xxx \
  --api-base https://api.deepseek.com/anthropic

# Add another
cce add glm \
  --provider zhipu \
  --model glm-5.1 \
  --api-key xxx \
  --api-base https://open.bigmodel.cn/api/anthropic

# List environments
cce list

# Run Claude Code with a specific environment
cce --env deepseek

# Pass any claude arguments through
cce --env deepseek -p "say hello"
cce --env deepseek --resume

Commands

| Command | Description | |---------|-------------| | cce --env <name> | Run Claude Code with the specified environment | | cce --env <name> <args...> | Run with extra claude arguments | | cce add <name> [options] | Add a new environment | | cce remove <name> | Remove an environment | | cce list | List all environments | | cce activate <name> | Set default environment | | cce doctor | Show current environment config | | cce import <file> | Import environment from file | | cce export [--env <name>] <file> | Export environment to file | | cce version | Print version |

Add Options

| Option | Description | |--------|-------------| | --provider | Provider name (e.g. deepseek, zhipu, openai) | | --model | Model name (e.g. deepseek-v4-flash, glm-5.1) | | --api-key | API key | | --api-base | API base URL | | --claude-bin | Path to claude binary | | --extra-env K=V | Extra environment variables (repeatable) |

Config Storage

~/.config/cce/
├── default          # Active default env name
└── envs/
    ├── deepseek.env
    └── glm.env

Each .env file:

CCE_PROVIDER=deepseek
CCE_MODEL=deepseek-v4-flash
ANTHROPIC_API_KEY=sk-xxx
ANTHROPIC_BASE_URL=https://api.deepseek.com/anthropic

File permissions are set to 600 to protect API keys.

How it works

cce launches claude as a child process with:

1. Environment variables — sets ANTHROPIC_API_KEY, ANTHROPIC_BASE_URL, etc. in the process env
2. --settings override — injects a JSON settings blob to override the env block from ~/.claude/settings.json (which would otherwise take precedence)

This approach:

• Does not modify ~/.claude/settings.json
• Does not interfere between terminals
• Your normal claude usage without cce is unaffected
