MCP Server Tester 🔌

Node.js Express Glassmorphism

Technical Approach 🛠️

1. Minimalist Architecture

  • Single endpoint (/test-mcp) with layered validation
  • Client-server separation (public/ vs server.js)
  • Stateless operation (no database)

2. Validation Pipeline

Frontend → Sanitize Input → Validate URL → Test Connection → Return Diagnostics

  • Removes backslashes/whitespace
  • Verifies URL structure
  • Tests actual connection with 5s timeout

3. Key Features

  • Instant visual feedback (success/error states)
  • Hardware-accelerated CSS animations
  • Responsive glassmorphism design
  • Detailed HTTP status reporting

Quick Start 🚀

git clone https://github.com/harshaagrawal20/MCP-server-tester.git cd MCP-server-tester npm install express cors body-parser axios node server.js

Access: http://localhost:5000
