ChatGPT dots (tested on ChatGPT Pro), Custom MCP server relay on your own Cloudflare account

Overview

Hitesh Patel (@deadbeef101010) built a desk gadget for the creator's ChatGPT dot. The dot can set it to READY, BUSY or ALERT, so you can see when your agent is working or needs you. It runs CircuitPython on a LilyGo T-Display S3 and reaches ChatGPT through a relay on your own Cloudflare account, designed to fit the free plan. The MIT-licensed repo is labelled a preview: tested on ChatGPT Pro, with claiming and pairing tested on iPhone; running it on battery is untested.

How it works

You deploy the relay to Cloudflare with Wrangler (npm run setup), claim it with a passkey and save the recovery codes, then add the board from your relay in Chrome, Edge or Chromium on the computer it is plugged into. Pairing is a button press plus a QR scan approved on your phone. In the ChatGPT desktop app you add the relay as a custom MCP server with OAuth and approve the Dot Gadget it can control. Then say “Set my Dot Gadget to BUSY”, or add a standing instruction to set it to ALERT whenever it needs your attention.

Hardware

  • LilyGo T-Display S3
  • USB-C data cable
