clodxy 0.2.1

Claude Code to OpenAI-compatible API proxy

clodxy

A simple custom proxy for Claude Code -> Any (OpenAI-compatible) Backend.

Supports the bare minimum necessary (messages, streaming, tools, vision).

Security Warning

NEVER expose this proxy to the public internet. This proxy is designed for local-only use and has no authentication or authorization mechanisms. The moment you bind this to a public-facing interface, you're inviting anyone on the internet to use your API keys and backend credentials. That's a skill issue waiting to happen. Keep it local.

Requirements

• Python 3.12+
• Claude Code CLI must be installed
• uv (for running from source)

Installation

No installation needed - run directly via uvx:

uvx clodxy

Configuration

Create a config file at ~/.config/clodxy/config.json (or set CLODXY_CONFIG to customize the path).

See config.example.json for reference:

{
  "backends": {
    "openai": {
      "api_base": "https://api.openai.com/v1",
      "api_key": "sk-your-api-key-here",
      "skip_last_assistant_message": false,
      "models": {
        "gpt-4o": {
          "context_size": 128000,
          "reasoning": false,
          "vision": true
        }
      }
    }
  },
  "default": {
    "backend": "openai",
    "model": "gpt-4o"
  }
}

Configuration Options

Backend fields

• api_base - The base URL of the OpenAI-compatible API
• api_key - API key for the backend (optional, defaults to "not-needed")
• skip_last_assistant_message - Skip the last assistant message in the Anthropic→OpenAI conversion. Only applies when both this is true AND the model has reasoning: true. Enable this for backends like llama.cpp that don't accept assistant prefills as the final message.

Model fields

• context_size - Maximum context window size in tokens
• reasoning - Whether this is a reasoning/thinking model (e.g., o1, o3-mini, deepseek-reasoner)
• vision - Whether this model supports vision/images

Usage

Run clodxy - it will start the proxy and launch Claude Code:

clodxy
clodxy /path/to/project

CLI Options

clodxy --help              # Show help
clodxy --version           # Show version
clodxy --list              # List available backends and models
clodxy --validate-config   # Validate configuration
clodxy --port 9000         # Custom port (default: auto-assign)
clodxy --host 0.0.0.0      # Custom host

Passthrough

Use -- to separate clodxy options from claude options:

clodxy --port 9000 -- --prompt "help me debug"
