ChatGPT App Starter Kit (MCP + SSE + Vercel)

Body

I open-sourced a minimal starter kit for building ChatGPT Apps backed by an MCP server
(Streamable HTTP + SSE) deployed to Vercel.

This exists because I kept running into the same MCP / SSE / CORS issues and wanted a
small, auditable reference instead of a large framework.

Free repo (MIT):

There’s also an optional Pro package with additional examples and practical templates
for people who want monetization scaffolding and a submission checklist:

No hype, no guarantees — just a working reference implementation.
Feedback welcome.

hey @shuddha2021, Nice work this is actually a useful contribution
It might help to add a short “common pitfalls” section in the README (timeouts, headers, edge vs serverless differences), since those are the things people usually hit first
