Open Rube is an open-source project implementing the Rube framework, designed to transform AI assistants into active agents capable of executing tasks across over 500 applications. It targets users seeking to empower their AI with direct action-taking capabilities within a chat interface, automating complex workflows across platforms like Slack, Notion, and GitHub. The primary benefit is enabling AI to move beyond suggestions to direct execution, streamlining user interactions with digital tools.

How It Works

Open Rube leverages Composio's framework, specifically its experimental Tool Router and Model Context Protocol (MCP), to bridge AI models with external applications. The Tool Router intelligently discovers and selects appropriate tools based on user intent, manages authentication, and executes actions, potentially in parallel. MCP provides a standardized, streaming protocol for AI-tool communication, maintaining session context. The core workflow involves user input processed by an AI model (e.g., GPT-5), which then directs the Tool Router to find, authenticate, and execute the necessary application actions before returning results to the user.

Quick Start & Requirements

• Primary install/run command: npm install followed by npm run dev.
• Prerequisites: Node.js 20+, npm/yarn/pnpm, a Composio account and API key, a Supabase project, and an OpenAI API key.
• Setup: Requires cloning the repository, installing dependencies, setting up environment variables (.env.local), configuring Supabase Auth (e.g., Google OAuth), and running a Supabase SQL script for database tables.
• Links: Composio Official Website, Composio Documentation, Composio GitHub, Tool Router Quick Start, Next.js Docs, Vercel AI SDK, Supabase Docs.

Highlighted Details

• Supports over 500 application integrations.
• Features an AI-powered chat interface utilizing OpenAI's GPT-5 model.
• Secure user authentication managed via Supabase Auth.
• Real-time streaming of AI responses and tool execution visibility.
• Built with modern web technologies: Next.js 15, React 19, TypeScript, Tailwind CSS, and Supabase.

Maintenance & Community

Contributions are welcomed via pull requests. No specific community channels (e.g., Discord, Slack) or roadmap links are provided in the README.

Licensing & Compatibility

The project is released under the MIT License, which generally permits commercial use and integration into closed-source projects.

Limitations & Caveats

The core "Tool Router" functionality is explicitly labeled as "experimental," suggesting potential instability or ongoing development. The README mentions both GPT-4 (in features) and GPT-5 (in technical architecture) as the AI model, requiring clarification on the intended or currently supported model.
