Claude Code API Key Manager

A simple bash-based tool to manage multiple Claude API keys for different projects and easily switch between them.

This has been written so that Claude Code can be more efficiently used with API keys in different Workspaces, without requiring the oauth flow for generating the keys, allowing you to distribute keys you have generated from the Anthropic console individually without providing access to the console.

The default behaviour of all keys from the oauth flow being in a single "Claude Code" Workspace can make FinOps difficult for organizations using Claude Code.

Features

• Store multiple API keys with project names
• Switch between different API keys
• Interactive menu interface
• Command-line interface for scripting
• Secure storage in JSON format
• Masked key display for security

6. Save current key as default
7. Exit

Storage

• API keys are stored in ~/claude-api-project-keys.json
• Claude configuration is stored in ~/.claude.json
• Both files are created automatically if they don't exist

• Keys are stored in JSON format in your home directory
• The interactive menu displays masked keys (showing only first 8 and last 4 characters)
• No keys are logged or displayed in plain text during normal operation
