Claude Code Source

What it does

This project provides a source-run implementation of the Claude Code CLI, enabling developers to run and customize Claude Code workflows directly using Bun. It extends the original functionality by adding multi-provider support, allowing the CLI to route traffic through OpenRouter to access various LLMs beyond just Anthropic's native API.

Tools

The project exposes a comprehensive set of CLI-based tools for agentic coding, including:

• auth: Manage API keys and authentication for Anthropic and OpenRouter.
• model: Interactive model switching (e.g., /model sonnet, /model opus).
• cli: Core execution engine for running agentic coding tasks from the shell.
• provider-management: Configuration for routing traffic to different model providers.

Installation

To run this server from source, use the following configuration in your claude_desktop_config.json (assuming the repo is cloned locally):

      "args": ["run", "src/entrypoints/cli.tsx"],
      "cwd": "/path/to/claude-code-source"

  }
}
