Complete Guide to MCP Orchestration with Cursor IDE

What is Cursor IDE?

Cursor IDE is an AI-first code editor built for productivity. It features Claude AI integration, smart autocomplete, and now supports Model Context Protocol (MCP) for connecting external services. Combined with Nexus, Cursor becomes a powerhouse for building SaaS applications.

Why Use Nexus with Cursor?

Instead of configuring 5-10 individual MCP servers in Cursor, Nexus acts as a single gateway that orchestrates all your services:

• One Connection: Configure Nexus once instead of multiple MCP servers
• Intelligent Routing: Nexus automatically determines which services to call
• Credential Management: Securely store API keys in one place
• Natural Language: Ask Claude to "deploy to Vercel" and Nexus handles the rest

Step-by-Step Setup Guide

1. Install Nexus MCP Client

npm install -g @nexus-mcp/client

2. Get Your Nexus API Token

Sign up at Nexus and generate an API token from your dashboard. Free tier gives you 3 orchestration calls/year to test.

3. Configure Cursor

Open Cursor settings (Cmd/Ctrl + ,) and add to your MCP configuration:

{
  "mcpServers": {
    "nexus": {
      "command": "nexus-mcp",
      "args": ["--token", "YOUR_API_TOKEN"],
      "env": {
        "NEXUS_API_URL": "https://nexus-worker.nandawinartha1.workers.dev"
      }
    }
  }
}

4. Configure MCP Server Credentials

Add credentials for services you want to use (Stripe, Supabase, GitHub, Vercel, Google Cloud Run) at Nexus Dashboard → Credentials.

5. Test the Integration

Restart Cursor and open Claude (Cmd/Ctrl + L). Try:

"Create a Next.js SaaS app with Stripe subscription payments and Supabase authentication, then deploy to Vercel"

Watch as Nexus orchestrates multiple MCP servers to complete the task!

Real-World Use Cases

E-commerce SaaS

"Build an e-commerce dashboard with Stripe payments, product management in Supabase, and automated Vercel deployment"

Mobile Backend

"Set up a REST API with Google Cloud Run, connect to Supabase database, and configure GitHub Actions for CI/CD"

Analytics Platform

"Create analytics pipeline with data stored in Supabase and visualizations deployed to Vercel"

Comparison: Cursor with vs without Nexus

Advanced Tips

• Use Specific Commands: "Deploy to Vercel using production branch" is more precise than "deploy"
• Check Quota: Monitor your plan usage in the Nexus dashboard
• Enable Caching: Nexus caches execution plans to save tokens
• Combine Services: Nexus shines when orchestrating 3+ services in one task

Troubleshooting

Issue: Cursor doesn't recognize Nexus commands

Solution: Restart Cursor completely and verify the MCP config path is correct

Issue: "Quota exceeded" error

Solution: Upgrade to Standard tier ($20/year for 2,000 plans)

Issue: Service credentials not working

Solution: Verify credentials in dashboard and ensure they have proper permissions

Conclusion

Nexus transforms Cursor IDE from a powerful editor into an intelligent orchestration platform. By abstracting away MCP server complexity, you can focus on building features instead of managing integrations.
