Don’t blame the author for the chrome only demo, blame Apple, and this bug from 2014! https://bugs.webkit.org/show_bug.cgi?id=127102

Show HN: I built an AI Chess Coach w/o4-mini and Stockfish

seanobannon — Tue, 15 Jul 2025 14:56:19 +0000

I built a simple chess bot that pairs o4-mini w/reasoning grounded in Stockfish’s engine analysis. It explains moves clearly, suggests tactics, and helps you understand why moves are good (or bad).

Try it out here: https://www.chesscoachgpt.com/

Would love feedback.

New comment by seanobannon in "Ask HN: Has anyone managed to implement OAuth on an MCP server?"

seanobannon — Thu, 26 Jun 2025 22:26:30 +0000

Yep, I ran into a few issues wiring up OAuth over the last few weeks building a ChatGPT connector so built this library to help folks get up and running quickly.

Let me know if you have any questions on it

Show HN: Self-Hosted OAuth Authentication Library for MCP Servers

seanobannon — Thu, 26 Jun 2025 16:31:11 +0000

Hey HN,

The latest MCP spec (https://modelcontextprotocol.io/specification/2025-06-18/bas...) requires MCP Servers implement OAuth for authenticating users and authorizing access to tools and resources. I spent way too long wiring up OAuth to build a ChatGPT connector and decided to wrap the pain into a library: @mcpauth/auth.

What it is:

- Self-hosted OAuth server, built for Model-Context-Protocol

- Single authenticateUser() hook, so you plug in whatever session logic you already have (NextAuth, Auth.js, plain cookies, JWT, you name it)

- Adapters: Next.js and Express; stores: Drizzle or Prisma

- ISC licensed, no calls home

Quick start is ~5 min: npm i @mcpauth/auth, add two route handlers, set three env vars.

Live demo: https://mcpauth-nextjs.vercel.app/

If you’re building an MCP server or any internal AI tool that needs proper OAuth, I’d love feedback — especially on edge cases or new functionality.

seanobannon — Wed, 25 Jun 2025 19:04:51 +0000

Completely agree - and yet auth is still surprisingly difficult to set up, so I built a library to simplify the setup. In this repo, there is:

- a Typescript library to set up ChatGPT-MCP compatible auth

- Source code for an Express & NextJS project implementing the library

- a URL for the demo of the deployed NextJS app that logs ChatGPT tool calls

Should be helpful for folks trying to set up and distribute custom connectors.

I couldn’t find any great examples of MCP auth, so made this demonstrate an oauth flow recently - https://github.com/OBannon37/chatgpt-deep-research-connector...

Show HN: Custom OAuth Connector Example for ChatGPT Deep Research

seanobannon — Mon, 09 Jun 2025 21:19:32 +0000

I subscribe to a ton of newsletters and always wanted to include them as sources with ChatGPT Deep Research. With the launch of Custom Connectors last week, this is finally possible. This repo is a minimal working example of a Deep Research connector with OAuth, built to hook up your custom data sources.

The official docs for custom MCP connectors are sparse, and there wasn't a complete example at launch. I figured sharing this Next.js demo (built using Auth.js and node-oauth2-server) could help others get started quicker.

Security hasn't been thoroughly vetted, so definitely proceed with caution.

Hope it helps folks hacking on MCP integrations!

Show HN: Clau-Perator – Computer Use Demo with Claude 3.7

seanobannon — Wed, 05 Mar 2025 19:57:11 +0000

I built Clauperator (No affiliation with Anthropic/OpenAI) as a demo to explore how Anthropic’s Claude 3.7 model can handle browser based tasks. For example, data entry, web research, or other workflows that typically require manual toil. It’s free to try, still definitely a demo, and I’d love feedback from the HN community.

It can persist cookies from logins (and we don't store passwords!), which is really interesting to try out how Claude works with your current business tools like HubSpot, Google Sheets, etc. but be cautious with entering real credentials (monitor it and make sure you don't send it down websites where it can get prompt injected!)

Behind the scenes, this uses K8s as orchestration w/Websockets for realtime messaging, and [Browserbase](https://www.browserbase.com/) for hosting a Chromium instance.

If you’re curious, or have ideas for improvement, I’d be grateful to hear your thoughts.

Depending on interest, I'm open to open-sourcing this or consulting with folks that need more domain/business-specific browser-based agents. There's a lot of infrastructure behind the scenes that goes in to making something like this work! I might do a write-up on that next week.
