Rube

Rube

by Composio

Model-Context-Protocol (MCP) server that exposes hundreds of integrated apps to AI assistants

See https://rube.app

Features

• Acts as a Model-Context-Protocol (MCP) server built on the Composio integration platform
• Connects an AI assistant (Cursor, Claude Desktop, VS Code, custom MCP clients) to 500+ business and productivity applications
• Marketplace of pre-built app integrations and connectors (Gmail, Slack, Notion, GitHub, Linear, Airtable, etc.)
• Translates plain-English instructions from an AI assistant into correct API calls (no manual code required)
• Centralized authentication and connection management via Composio (OAuth 2.1, per-app permissions)
• Team sharing: single Rube URL can provide team access; teammates may bring their own keys or share connections
• Designed to avoid “tool limits” by surfacing a large app ecosystem behind one MCP tool
• Built-in security practices inherited from Composio (end-to-end encryption, SOC2-aligned controls)

Superpowers

Rube is for teams and developers who want to give AI assistants real-world agency across a large ecosystem of existing apps without writing and maintaining hundreds of API integrations.

• Instant access to many apps through conversational commands — ask the AI to create issues, send emails, update databases, or post messages and Rube will handle the API plumbing
• Reduces engineering time spent on boilerplate integrations and OAuth management
• Portable across MCP-compatible clients — integrations follow you when you switch AI clients
• Good fit for content ops, customer ops, developer workflows, and knowledge management automations driven by an AI assistant

Practical usage examples

• Content engine: prompt the AI to research a topic, draft an SEO-optimized article, save the draft to Google Docs or Notion, and create a tracking row in Airtable — all in one conversational flow.
• Customer/email automation: “Send a follow-up email to the last demo attendee” — AI drafts the message and Rube sends it through your connected Gmail account.
• Issue triage: “Create a Linear issue for this bug and assign it to Sam with priority high” — AI creates and populates the issue using your Linear integration.
• CRM updates: “Add this user’s latest notes to their Notion CRM entry and tag as ‘lead’” — AI updates Notion via Rube.
• Dev workflows: “Open a GitHub issue with the failing test output and link the related PR” — streamlines developer handoffs.

Example prompt to an AI connected to Rube:
“Create a Notion page titled ‘Q4 Content Plan’ with the following rows: ‘Topic A — draft due 2025-11-10’, ‘Topic B — draft due 2025-11-17’. Add me and @marketing to the page with edit access.”

Notes & Risks

• Rube centralizes a lot of app permissions; teams should review access controls and the Composio dashboard to manage/revoke app authorizations
• Because Rube exposes many integrations to an AI agent, validate prompts and guardrails before giving write permissions in production workflows (consider read-only for initial testing)
• Confirm compliance needs (data residency, audit logs) with Composio if you have strict regulatory requirements
