Overview

This guide covers installation, authentication flows, and troubleshooting for MCP tools in Cursor.

Installation

1. Check Node.js Installation

   • Make sure Node.js is installed on your system by running:

     node -v
     

   • If Node.js is not installed, download it from nodejs.org.

   • Note: For best results, use Node.js 10 or higher. We don’t suppport earlier versions.

2. Install MCP Tools

   • Paste the npx command generated by mcp.composio.dev into your terminal:

     # Example:
     Your generated code
     

   • This command installs the MCP tools and configures them for use in Cursor.

3. Verify Installation
   • Open Cursor settings and navigate to MCP to confirm the MCP servers are installed.
   • If everything looks correct, you can start using MCP features directly in Cursor.
