ReopenAI

Make all AI tools interoperable. Turn any desktop AI client into a standard API endpoint and MCP Server.

ReopenAI acts as a unified bridge, enabling any AI coding assistant (Claude Code, Cursor, Cline, etc.) to freely control and leverage any subscription-based desktop AI app (Antigravity, Cursor, Codex, ChatGPT, ChatWise, Grok).

We offer two distinct integration methods:

Method 1: Native Model Provider (API Proxy) —— 🌟 recommended

This is the most powerful method. It treats your Desktop AI app (e.g., Antigravity) directly as the core backend brain. We launch a local Anthropic-compatible API proxy (/v1/messages) that routes standard inference requests seamlessly into the desktop app via CDP, making Claude Code think it's talking to the official endpoints!

Usage

1. Launch the target AI app (with CDP debugging enabled):

   /Applications/Antigravity.app/Contents/MacOS/Electron --remote-debugging-port=9224
   

2. Start the API Proxy (using opencli):

   npm i -g @jackwener/opencli
   OPENCLI_CDP_ENDPOINT=http://127.0.0.1:9224 opencli antigravity serve --port 8082
   

3. Connect your tool (Example with Claude Code):

   ANTHROPIC_BASE_URL=http://localhost:8082 claude
   

🎉 Key Proxy Features:

• Auto context isolation by detecting new sessions and actively hitting New Conversation.
• Automatic model translation: transparently maps incoming LLM names (e.g., gemini-1.5-pro, claude-3-7-sonnet-20250219) to actual dropdown UI elements and selects them automatically!
• Instant generation feedback by natively tracking interface rendering states.

Method 2: MCP Server (Side Tooling)

If you already have a primary foundational LLM, and just want to treat your desktop AI as an external tool/skill (e.g. "Go find X in my ChatGPT history"), you can bridge them using the Model Context Protocol (MCP).

How it Works

Claude Code / Cursor / Cline / ...
        ↓ MCP Protocol (stdio)
    reopenai (this project)
        ↓ child_process
    opencli <app> <command>
        ↓ CDP Protocol
    Electron AI Apps

Quick Start

Add to your .mcp.json:

{
  "mcpServers": {
    "reopenai": {
      "command": "npx",
      "args": ["-y", "@jackwener/reopenai"]
    }
  }
}

Once hooked up, your assistant can natively trigger these types of commands:

• "Check if Antigravity is connected" → calls ai_status
• "Ask Cursor to write a sorting algorithm" → calls ai_ask
• "Read the latest conversation from ChatGPT" → calls ai_read
