Claude Code Provider Manager - Switch between multiple Claude Code API providers seamlessly.

Overview

Clauver is a powerful CLI tool that allows you to easily manage and switch between different Claude Code API providers, including:

• Native Anthropic - Use your existing Claude Pro/Team subscription
• Z.AI - Zhipu AI's GLM models
• MiniMax - MiniMax AI's MiniMax-M2 model
• Kimi - Moonshot AI's Kimi K2 model
• DeepSeek - DeepSeek AI's DeepSeek models
• Custom Providers - Add your own provider

⚠️ Platform Compatibility: This script has been tested and confirmed to work on Linux only. While it may work on other Unix-like systems (macOS, WSL), compatibility is not guaranteed.

Features

• Easy Provider Switching - Switch providers with a single command
• Secure API Key Management - API keys encrypted with age (X25519)
• Configuration Testing - Test provider configurations before use
• Default Provider - Set a default provider for quick access
• Auto-completion - Tab completion for bash, zsh, and fish
• Quick Setup Wizard - Interactive setup for beginners
• Status Monitoring - Check all configured providers at once
• Self-Update - Update to the latest version with a single command
• Encrypted Storage - Secrets encrypted at rest, decrypted in memory only

Requirements

• claude CLI - Install with: npm install -g @anthropic-ai/claude-code

# Set default provider
clauver default zai

# Show current default
clauver default

# Use default provider (no arguments needed)
clauver "What can you help me with?"

Manage Providers

clauver list         # List all providers
clauver status       # Check provider status
clauver test <name>  # Test a provider
clauver migrate      # Migrate plaintext secrets to encrypted storage
clauver default      # Show or set default provider
clauver version      # Show current version and check for updates
clauver update       # Update to the latest version
clauver help         # Show help

Examples

Basic Usage

# First time setup
clauver setup

# Configure a provider
clauver config minimax
# Enter your MiniMax API key when prompted

# Use the provider
clauver minimax "Write a Python function to calculate fibonacci numbers"

# Check status
clauver status

Testing Configuration

# Test a specific provider
clauver test zai

# Test all providers
clauver status

Setting a Default Provider

# Set your preferred default provider
clauver default minimax

# Verify the default is set
clauver default

# Use the default provider
clauver "Help me write a bash script"

# Change your default anytime
clauver default anthropic

Version Management

# Check current version and available updates
clauver version

# Update to the latest version
clauver update

# Both commands work without confirmation prompts
# Update will show "already up to date" if on latest version

Encryption & Key Management

Encryption Overview

Clauver automatically encrypts all API keys using age, a modern and secure file encryption tool. Your secrets are:

• Encrypted at rest on disk
• Only decrypted into memory when needed
• Never written to disk as plaintext

Key Backup

CRITICAL: Back up your encryption key immediately after installation!

# Your encryption key location
~/.clauver/age.key

# Back up your key (choose one method):
cp ~/.clauver/age.key ~/backup/clauver-age.key.backup
cp ~/.clauver/age.key /path/to/external/drive/

Without your age key, you cannot decrypt your secrets!

Key Recovery

If you lose your encryption key:

# 1. If you have a backup, restore it:
cp ~/backup/clauver-age.key.backup ~/.clauver/age.key
chmod 600 ~/.clauver/age.key

# 2. If you don't have a backup, you'll need to reconfigure:
rm ~/.clauver/secrets.env.age  # Remove encrypted file
clauver config <provider>       # Reconfigure your providers

Migrating from Plaintext

If you're upgrading from an older version with plaintext secrets:

# Check your current storage type
clauver status

# Migrate to encrypted storage
clauver migrate

# Verify encryption is active
clauver status  # Should show "🔒 Secrets Storage: Encrypted"

Using Configs on Multiple Machines

Your encryption key is portable! To use your configs on another machine:

# On original machine - backup both files:
cp ~/.clauver/age.key ~/backup/
cp ~/.clauver/secrets.env.age ~/backup/

# On new machine - restore both files:
mkdir -p ~/.clauver
cp ~/backup/age.key ~/.clauver/
cp ~/backup/secrets.env.age ~/.clauver/
chmod 600 ~/.clauver/age.key
chmod 600 ~/.clauver/secrets.env.age

# Verify it works:
clauver list

Custom Provider

# Add a custom provider
clauver config custom
# Provider name: my-provider
# Base URL: https://api.example.com/anthropic
# API Key: your-api-key
# Model: your-model

# Use it
clauver my-provider "Hello"

Auto-completion

Clauver includes auto-completion for bash, zsh, and fish.

After installation, try:

clauver <TAB><TAB>        # Show available commands
clauver z<TAB>            # Complete to 'clauver zai'

Testing

Clauver includes a comprehensive test suite with unit tests, integration tests, security validation, and performance benchmarks.

Quick Test

# Run all tests
cd tests/
make test

# Or use the test runner
./run_all_tests.sh

Configuration Storage

Clauver uses an encrypted configuration system:

~/.clauver/
├── secrets.env.age        # Encrypted API keys (age encrypted)
├── age.key                # Encryption key (chmod 600) - BACK THIS UP!
├── config                 # Provider configurations (chmod 600)
├── bin/
│   └── clauver           # Installed binary
└── completions/          # Auto-completion files

Configuration Files

• secrets.env.age: Encrypted API keys using age (X25519) encryption
  • ZAI_API_KEY
  • MINIMAX_API_KEY
  • KIMI_API_KEY
  • DEEPSEEK_API_KEY

Secrets are only decrypted into memory, never written to disk as plaintext

• age.key: Your encryption key (automatically generated)

  • CRITICAL: Back up this file! Without it, you cannot decrypt your secrets
  • Portable across machines - copy this file to use your configs elsewhere
  • Located at: ~/.clauver/age.key

• config: Stores provider configurations:

  • Base URLs, models, and endpoint IDs
  • Custom provider definitions
  • default_provider - Your preferred default provider

Security Features

• Encrypted at Rest: API keys are encrypted using age (modern, secure encryption)
• Memory-Only Decryption: Secrets decrypted directly into memory via process substitution
• No Plaintext on Disk: Encrypted file is never written as plaintext
• Session Caching: Secrets decrypted once per session for performance
• Automatic Key Generation: Encryption key auto-generated on first use
• Migration Support: Seamlessly migrate from plaintext to encrypted storage

Troubleshooting

Having issues? See complete troubleshooting guide.

Common fixes:

• PATH issues: export PATH="$HOME/.clauver/bin:$PATH"
• Missing dependencies: npm install -g @anthropic-ai/claude-code
• age encryption: sudo apt install age (or brew install age)
• Provider tests: clauver test <provider>
• Status check: clauver status
