Rube MCP Server

Rube is a Model‑Context‑Protocol (MCP) server built on the Composio integration platform. It connects AI chat tools to more than 500 business and productivity applications – things like Gmail, Slack, Notion, GitHub, Linear, Airtable, and many others. Once installed, you can ask your AI tool to perform everyday tasks (e.g. “send an email to the latest customer,” “create a Linear issue,” “update my Notion database,” or “post an update to Slack”) and Rube will securely talk to the relevant apps on your behalf. Instead of writing complex API integrations yourself, you just tell your AI assistant what you want to do.

Why Rube?

• Works everywhere – Rube integrates with major AI clients like Cursor, Claude Desktop, VS Code, Claude Code and any custom MCP‑compatible client. You can switch between these clients and your integrations follow you.
• 500+ tools out of the box – Composio has connectors for hundreds of SaaS and internal apps; Rube exposes them to your AI so you can automate emails, tasks, spreadsheets, calendars, documents and more with a single server.
• Human‑friendly commands – Rube translates plain‑English instructions into the correct API calls. A Slack‑like chat example on the site shows how Rube takes “Find my last 5 customers in Airtable” and “Post them to Slack” and handles the API requests under the hood.
• Team‑ready – You can start alone and later invite teammates. A single Rube URL gives your team access to every connected app; you can bring your own API keys, share connections across the team or keep them private. There’s no limit on the number of tools you connect.
• Built on Composio – Rube uses Composio’s infrastructure for authentication, security and integration management. Composio handles OAuth 2.1 flows, end‑to‑end encryption and SOC 2 compliant practices.

Prerequisites

1. An AI client that supports the MCP protocol – Rube provides instructions for Cursor, Claude Desktop, VS Code, Claude Code and any generic MCP client.
2. Composio or client account – Rube uses Composio’s authentication and you may need to sign in during setup.
3. API/credential access to the apps you want to automate – many integrations use OAuth; others require an API key. Rube can handle both.

Installing Rube

Cursor

1. In Cursor, click Add MCP Server (e.g. from the “MCP Tools” sidebar).
2. In the “Install MCP server?” dialog choose Rube with the following details:

• Name – rube
• Type – streamableHttp
• URL – https://rube.composio.dev/?agent=cursor .

3. Confirm the installation. Rube will show as “Needs login”; click this to authenticate.
4. Follow the sign‑in flow in your browser and authorise the apps you wish to use. When the connection shows as authenticated you can start using natural‑language commands in Cursor chat.

Claude Desktop

1. Copy the Rube MCP URL (https://rube.app/mcp – you can click Copy in the installation modal).
2. Open Claude Desktop → Settings → Connectors. Choose Add custom connector.
3. Enter a name (e.g. Rube), paste the MCP URL, and click Add. You may need to confirm that you trust the connector.
4. Click Connect next to the new connector and complete the web‑based authentication. After connecting, you can start using Rube inside Claude Desktop to access hundreds of apps.

VS Code (ChatGPT or Claude Extensions)

1. Open a terminal and run the setup command:

npx @composio/mcp@latest setup "https://rube.app/mcp" "rube" --client vscode

This installs the Rube MCP server into VS Code. 2. Restart VS Code after the command completes. The configuration will add Rube to the list of MCP servers. 3. Open VS Code settings (search for Chat > MCP) and ensure the following are enabled:

• Chat > MCP: Autostart – automatically starts MCP servers for new chats.
• Chat > MCP: Discovery – enables discovery o
