Connect ChatGPT (web)

This page is for ChatGPT in the browser (chatgpt.com) and regular chat in the ChatGPT desktop app. Codex – including Codex CLI and the Codex tab in the ChatGPT desktop application – uses a different setup. See Connect ChatGPT / Codex.

Chartbuddy Hub MCP is not available here yet

Chartbuddy Hub connects over local stdio MCP. ChatGPT in the browser and regular desktop chat cannot reach a local Chartbuddy Hub process, and we do not ship a remote MCP endpoint yet – so regular ChatGPT cannot connect to Chartbuddy Hub MCP today.

What you can use instead

Option	Best for
ChatGPT / Codex	Full Chartbuddy Hub MCP in Codex CLI or the desktop Codex tab
Embed docs	Charts inside ChatGPT conversations via HTML artifacts and the @chartbuddy.io/embed widget

For Embed, start with llms.txt, then Getting started and Visual QA in the Embed docs.
