Summary

Rube is a Model Context Protocol (MCP) server designed to bridge AI clients with over 500 business and productivity applications, including Gmail, Slack, and GitHub. It empowers users to automate tasks by issuing plain-English commands through their AI tools, eliminating the need for direct API integration. Rube targets AI developers and power users seeking a unified interface to control diverse software ecosystems, offering significant time savings and enhanced workflow automation.

How It Works

Rube functions as an MCP server built upon the Composio integration platform. It translates natural language instructions from AI clients into specific API calls for connected applications. This approach abstracts the complexity of managing numerous individual app APIs, allowing users to interact with tools like Airtable, Notion, or GitHub through simple chat commands. Composio handles the underlying authentication, security, and integration management, including OAuth 2.1 flows and end-to-end encryption.

Quick Start & Requirements

Installation can be done globally via npm (npm install -g @composio/rube) followed by rube setup, or directly using npx @composio/rube setup. Specific setup instructions are provided for AI clients such as Cursor, Claude Desktop, VS Code, and Claude Code, often involving registering the Rube MCP URL (https://rube.app/mcp). Prerequisites include an MCP-compatible AI client and authentication with the desired applications (via OAuth or API keys). Setup is estimated to take under five minutes.

Maintenance & Community

Support and feedback can be directed to support@composio.dev. Integration requests for unsupported apps can be submitted through the Composio community.

Licensing & Compatibility

The provided README does not specify a software license. This lack of explicit licensing information presents a significant adoption blocker, particularly for commercial use or integration into proprietary systems.

Limitations & Caveats

Rube is currently in beta, with paid plans anticipated in the future. Integrations for unsupported applications require user requests. The absence of a defined license is a critical caveat for potential adopters.
