Prompt:
Build a minimal TypeScript ChatGPT App: use @modelcontextprotocol/sdk with Express to expose a topMovers tool that hits Alpha Vantage’s TOP_GAINERS_LOSERS endpoint, that, on load, calls window.openai.callTool(‘topMovers’, { limit }), and renders responsive tables for the results inline in the widget. Have it run through a local server and ngrok. Please read through all the documentation here: https://developers.openai.com/apps-sdk/build/mcp-server
