Summary

Build production-ready MCP servers with the mcp-use framework and automatic widget registration.

  • Bootstrap with npx create-mcp-use-app and choose from three templates: starter (full-featured), mcp-apps (ChatGPT-optimized), or blank (minimal)
  • Define tools, resources, and prompts using Zod schemas with automatic validation and clear parameter descriptions
  • Automatically register React widgets from the resources/ folder as MCP Tools and Resources with dual-protocol support for MCP Apps and ChatGPT
  • Test locally with hot reload, use the Inspector UI at http://localhost:3000/inspector, and tunnel to ChatGPT before deploying with mcp-use start --tunnel
  • Deploy to mcp-use Cloud with yarn deploy for auto-scaled, HTTPS-enabled hosting with zero-downtime updates
