Rube was a universal AI tool-connectivity service from Composio that let AI chat clients act across apps; it was discontinued on May 16, 2026.
About
Rube was an AI tool-connectivity service built by Composio that let AI chat assistants interact with a wide range of external applications — including email, calendars, and work tools — so that users could automate everyday tasks through conversation. It is now discontinued: the service stopped accepting new signups on April 9, shut down Rube Chat on April 20, and fully closed on May 16, 2026, with all customer payments refunded.
The shutdown was announced as a transition rather than a disappearance of the capability. Composio now directs former Rube users to Composio For You, a successor offering that provides the same functionality through MCP (Model Context Protocol) and a CLI, using the same underlying tools that Composio reports power clients such as Claude Code and Cursor. Composio For You works with any MCP client and supports multiple accounts, so existing workflows can be rebuilt on the newer platform.

- Status: Rube is discontinued. New signups stopped April 9, Rube Chat ended April 20, and the full shutdown with refunds completed on May 16, 2026.
- Accounts not migrated: Composio did not automatically migrate Rube user accounts, so former users must set up connections again in Composio For You.
- Official resources: Composio maintains an X account (@ask_rube), a GitHub organization (composiohq), and a YouTube channel for updates and documentation.
Who It's For
Rube was aimed at technical users and everyday productivity seekers who wanted their AI assistants to do things rather than just talk — managing email, calendars, and workplace apps through chat. Developers and automation builders who used Rube are the natural audience for its successor, Composio For You, particularly those already working with MCP-compatible clients such as Claude Code or Cursor. Non-technical users who relied on Rube Chat will need to move to the MCP/CLI-based replacement, which assumes more comfort with developer tooling.
