🌐 HTTP Stream Integration
When running in HTTP mode, the server provides Server-Sent Events (SSE) at /sse:
# Start HTTP server
npx @ryancardin/noaa-tides-currents-mcp-server --http --port 3000
# Test the endpoint
curl -N http://localhost:3000/sse
# Or integrate with web applications
fetch('http://localhost:3000/sse')
.then(response => response.body.getReader())
.then(reader => {
// Handle streaming MCP responses
});
Use Cases for HTTP Mode:
- 🌐 Web Applications - Integrate with React, Vue, Angular apps
- 📱 Mobile Apps - REST-like access from mobile applications
- 🔗 API Gateways - Proxy through load balancers or API gateways
- 🧪 Testing - Easy curl-based testing and debugging
