MCP Server Implementation: What We Built and How We Monitor It

The Model Context Protocol (MCP) is the new standard for AI agents to interact with tools and data. Here's what we implemented on MyZubster Gateway.

🧠 What is an MCP Server?

An MCP Server exposes:

• Tools: Executable functions (e.g., /api/robot/assign)
• Resources: Accessible data (e.g., /api/tokens/balance/:userId)
• Prompts: Interaction templates for AI agents

Our gateway acts as a fully functional MCP server, serving both human users and AI agents.

🛠️ What We Implemented

1. Core Infrastructure

Component	Implementation
Server	Node.js + Express
Process Manager	PM2 with auto-restart
Reverse Proxy	NGINX + SSL (Let's Encrypt)
Domain	api.myzubster.com
Monitoring	Sentry for errors and performance

2. Tools (Endpoints)

Tool	Method	Description
/api/health	GET	Gateway health check
/api/robot/assign	GET	Assign robots to tasks
/api/tokens/balance/:userId	GET	Get token balances
/api/notifications	GET	Get user notifications
/api/messages	GET	Get user messages
/api/test-error	GET	Test Sentry error tracking

3. Monitoring with Sentry

We integrated Sentry for comprehensive monitoring:

javascript
const Sentry = require('@sentry/node');

Sentry.init({
  dsn: process.env.SENTRY_DSN,
  environment: process.env.NODE_ENV,
  tracesSampleRate: 0.1, // 10% in production
});

// Every request is traced
app.use(Sentry.Handlers.requestHandler());

// Every route has error capture
app.get("/api/robot/assign", (req, res) => {
  try {
    // Business logic
  } catch (error) {
    Sentry.captureException(error);
    res.status(500).json({ error: error.message });
  }
});

// Error handler
app.use(Sentry.Handlers.errorHandler());

What we monitor:

    Client tracking: Who calls which tools

    Performance: Response times per endpoint

    Errors: Even silent JSON-RPC errors

    Usage: Tool popularity and patterns

🔍 Why MCP Matters
Before MCP

    ❌ No standard protocol for AI agents

    ❌ Every integration was custom

    ❌ Hard to monitor usage

    ❌ Difficult to debug errors

After MCP

    ✅ Standardized AI-agent communication

    ✅ Consistent tool exposure

    ✅ Built-in monitoring

    ✅ Better debugging with context

💡 Lessons Learned

    Start with monitoring — You can't fix what you can't see

    Silent errors are dangerous — Capture everything

    Performance matters — Slow tools hurt AI agents

    Documentation is key — Both for humans and AI
