Nexus - One Gateway, All Your MCP Servers

Why Claude Desktop + Nexus?

Claude Desktop is Anthropic's standalone app that brings Claude AI to your desktop without needing a browser. Combined with Nexus MCP orchestration, it becomes a powerful command center for your entire development workflow.

What You'll Build

Natural language interface to all your dev tools
Deploy to Vercel with "deploy my app to production"
Manage Stripe subscriptions conversationally
Query and update Supabase database

Step-by-Step Setup

1. Install Claude Desktop

Download Claude Desktop from claude.ai/download. Available for macOS, Windows, and Linux.

2. Get Nexus API Token

3. Configure Claude Desktop MCP

Open Claude Desktop settings and add Nexus to your MCP configuration:

~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "nexus": {
      "command": "npx",
      "args": ["-y", "@nexus-mcp/client"],
      "env": {
        "NEXUS_API_TOKEN": "your_api_token_here",
        "NEXUS_API_URL": "https://nexus-worker.nandawinartha1.workers.dev"
      }
    }
  }
}

4. Add Service Credentials

Navigate to Nexus Dashboard → Credentials and add:

Stripe:Secret Key from dashboard
Supabase:URL + Service Role Key
Vercel:Personal Access Token
GitHub:Personal Access Token (for repos)

5. Restart Claude Desktop

Completely quit and restart Claude Desktop. You should see "Nexus MCP Connected" in the bottom toolbar.

Real-World Examples

Example 1: Deploy to Vercel

"Deploy my Next.js app to Vercel production using the main branch"

Claude Desktop → Nexus → GitHub (fetch code) → Vercel (deploy) → Response in seconds

Example 2: Stripe Subscription Management

"Show me all active subscriptions and refund the one for customer cus_ABC123"

Nexus lists subscriptions, confirms refund intent, processes via Stripe API

Example 3: Database Query

"Get all users from Supabase who signed up in the last 7 days"

Nexus translates to SQL, queries Supabase, returns formatted results

Advanced Orchestration

The real power comes from chaining multiple services in one command:

Complex Command Example

"Create a new customer in Stripe for john@example.com, add them to the 'users' table in Supabase, and send them a welcome email via SendGrid"

Nexus orchestrates: Stripe → Supabase → SendGrid in sequence, handling errors and dependencies automatically.

Troubleshooting

Issue: "Nexus MCP not connected"

→ Verify API token in config, restart Claude Desktop completely

Issue: "Service credentials invalid"

→ Check dashboard, re-save credentials, verify API permissions

Issue: "Quota exceeded"

→ Upgrade to Standard ($20/year for 2,000 plans)

Conclusion

Claude Desktop + Nexus transforms how you interact with development tools. No more switching between dashboards, CLI tools, and APIs - just natural language commands that orchestrate everything seamlessly.
