MCP Server Tester

MCP Server Tester 🚀 A web application that allows users to test the connectivity and functionality of an MCP server by providing its URL or installation code. 🔹 Features ✅ Accepts an MCP server URL or installation code ✅ Verifies connectivity and fetches response ✅ Displays results clearly ✅ Handles errors gracefully ✅ Deployed on Netlify (Frontend) and Render (Backend) 🔹 Tech Stack Frontend: HTML, CSS, JavaScript

Backend: Node.js, Express.js

Hosting: Netlify (Frontend), Render (Backend)

📌 Live Demo & Repository 🔗 Live App: creative-torte-69268c.netlify.app 🔗 GitHub Repository: https://github.com/kothagundlabhavitha/mcp-server-tester 🚀 How to Run the Project Locally 1️⃣ Clone the Repository bash Copy Edit git clone https://github.com/your-username/mcp-server-tester.git cd mcp-server-tester 2️⃣ Install Dependencies bash Copy Edit npm install 3️⃣ Start the Backend bash Copy Edit node server.js The backend will start on http://localhost:3000

4️⃣ Open the Frontend Open index.html in a browser

Or use Live Server extension in VS Code

📌 How It Works 1️⃣ Enter a valid MCP Server URL (e.g., from Smithery) 2️⃣ Click "Test MCP Server" 3️⃣ The app sends a request to the backend (Node.js on Render) 4️⃣ The backend checks the MCP server and returns the response 5️⃣ The result is displayed on the webpage ⚠️ Troubleshooting If you see "Cannot GET /", ensure the backend has a / route:

js Copy Edit app.get("/", (req, res) => res.send("MCP Server Tester Backend is running!")); If the frontend shows "Unexpected token '<'", your backend might be down. Check the Render logs for errors.

If "Failed to fetch", ensure the backend URL is correct in script.js:

js Copy Edit const backendUrl = "https://mcp-server-tester-e4xf.onrender.com"; 📌 Deployment Details Frontend: ✅ Netlify → creative-torte-69268c.netlify.app
