Summary
If you're building ChatGPT Apps and want to use MCP servers instead of OpenAI's native approach, this lets you deploy tools and interactive widgets on Cloudflare Workers. It's basically a bridge between ChatGPT and the Model Context Protocol using JSON-RPC 2.0, with support for rendering HTML/JS UIs in iframes. Production ready as of January 2026, though worth noting it's aimed at ChatGPT Business/Enterprise/Edu users since that's where Apps are available. The repo has solid traction with 800+ stars and passes most security audits. Useful if you're already invested in MCP tooling and want to extend it to ChatGPT without rewriting everything for their API.
