Rube by Composio

Getting your AI assistant to actually take actions in the tools you use every day — updating a CRM, sending a Slack message, creating a GitHub issue — typically requires complex integrations and authentication setups. Rube is a universal MCP (Multi-Client Platform) developed by Composio that eliminates that friction. It enables users to take actions across 600+ applications directly from within AI chat interfaces like Cursor, Claude, and VS Code, seamlessly managing authentication and tool selection behind the scenes. AI that can do things, not just answer questions.
