Clone the repository, install dependencies (npm install express cors body-parser axios), and run node server.js. The server listens on port 5000 by default. Use the web UI at http://localhost:5000 or send a POST /test-mcp request with a JSON body containing {"serverConfig": {"url": "https://example.com"}}.

Frequently asked questions
What are the runtime dependencies?
Node.js 14+ and the packages: express, cors, body-parser, and axios. No database is required.
How do I change the timeout or port?
Edit the constants in the server code: `const PORT = 5000;` and `const TIMEOUT = 5000;` (timeout in milliseconds).
Where does my data go?
The tool is stateless β no data is stored. Each request is validated, tested, and the result is returned immediately without logging or persistence.
What transport or authentication methods are supported?
The server itself uses HTTP and the API accepts POST requests with JSON. It tests any valid URL, but does not implement any authentication or custom transport layers.
