FAQ from Neon Auth MCP OAuth

What is this project?

It is a proof of concept (PoC) for a custom MCP OAuth flow using Next.js, Neon, Upstash Redis, and Neon Auth.

What are the dependencies and runtime requirements?

You need to set up a Neon database and Neon Auth, deploy to Vercel, and configure Upstash Redis via the Vercel Upstash Integration. Environment variables are required (see ./lib/config.ts).

How do I reset auth state if I run into issues?

Run rm -rf ~/.mcp-auth to clear stored authentication data from the mcp-remote package. MCP auth is noted as still flaky.

Can I run this locally?

Yes, clone the repository, set up the environment, and run npm run dev. Use npm run playground to start the MCP Inspector for debugging.

What transports or authentication does it use?

It uses a custom OAuth flow over HTTP/HTTPS (the MCP server endpoint is /api/v1/mcp). Authentication is handled via Neon Auth and OAuth tokens.
