mcp-for-next.js
Next.js App Router project where app/mcp/route.ts hosts a stateless MCP server through mcp-handler 2 and the MCP TypeScript SDK v2, serving the 2026-07-28 protocol natively with a compatibility layer for 2025-era Streamable HTTP clients. Includes a sample client script that lists tools and calls echo. For teams adding an MCP endpoint to an existing Next.js app on Vercel; no auth is wired.
Who it is for: Next.js teams exposing tools to MCP clients
Strengths
- Stateless Streamable HTTP; no Redis or session store required
- Current 2026-07-28 protocol plus 2025 Streamable HTTP compatibility
- Sample client script for smoke-testing the endpoint
Weaknesses
- No auth; remote MCP clients will need OAuth added
- Deprecated HTTP+SSE transport is not supported
- Only an echo tool; the README is a few lines
- No tests or Docker
- JavaScript, MCP TypeScript SDK v2, mcp-handler 2
openai-apps-sdk-examples
pnpm workspace with React widget sources, a Vite build that emits hashed HTML/JS/CSS bundles served on port 4444, and paired MCP servers in Node and Python (Pizzaz, kitchen-sink-lite, solar system, shopping cart, an OAuth-gated example). Widgets use the window.openai host API and _meta.ui.resourceUri to render inside ChatGPT. For developers building ChatGPT apps; test via developer mode and an ngrok tunnel.
Who it is for: Developers building ChatGPT apps with MCP and widgets
Strengths
- Node and Python MCP servers for the same widgets
- kitchen-sink-lite covers the full window.openai host API surface
- Shopping-cart example shows widgetSessionId state across tool calls
- Authenticated server demonstrates OAuth-gated tools
Weaknesses
- Examples only; no persistence or deploy config beyond BASE_URL
- Requires ChatGPT developer mode and a public tunnel to test
- Chrome 142+ needs a flag change to render widgets locally
- Maintainers may not review all PRs
- TypeScript, OpenAI Apps SDK, MCP TypeScript SDK, MCP Python SDK
- Needs ChatGPT developer mode, ngrok or a public host for testing
