Node.js
Node.js is a runtime environment that lets JavaScript code run outside a browser, directly on your machine. Originally, JavaScript lived only inside web pages; with Node.js, it’s also used to write servers and command-line tools. The TradingView MCP server is itself a Node.js program: without Node installed on your PC, it can’t start. Installing it (via winget, for instance) also brings along npm, the package manager that will download its dependencies.
